Guillermo Heredia, Starting Center Fielder

With Jarrod Dyson set to be a free agent, and Leonys Martin both ineffective and DFA’d twice, there has been some uncertainty among Seattle Mariners fans regarding who will patrol center field for the team in 2018. Luckily for Mariners fans, they have an internal option who is potentially an above-average player already playing for their favorite team: Guillermo Heredia.

At 26, Heredia is a bit old to just be emerging. Though unlike other players his age, his late arrival to the major leagues has nothing to do with his ability. Heredia defected from Cuba in January of 2015, just a few weeks before his 24th birthday. Before defecting, Baseball America ranked Heredia as the 11th best prospect in Cuba. He was signed by the Mariners in February 2016, after sitting out the entire 2015 season.

Heredia, considered by most to be a glove-first prospect, started the year hot with the bat in AA Jackson, hitting .293/.405/.376 in 260 plate appearances while living up to his defensive reputation. Heredia walked more times (36) than he struck out (32) and earned a promotion to AAA Tacoma after just 58 games. Heredia’s 35 AAA games—where he hit .312/.378/.414—were split by a cup of coffee when the major league club. In AAA, Heredia improved his strikeout rate to 9.6%, while his walk rate fell to 7.5%, but his combination of solid on-base skills and great defense earned him a call up to the majors for good on August 22nd.

Heredia made the most of his cup of coffee, hitting a solid .250/.349/.315, drawing 12 walks against just 15 strikeouts in a small sample of 107 plate appearances. Thanks to his strong on-base skills, and stellar defense, Heredia managed 0.4 WAR in just 45 games — with most of his playing time coming as a late-inning defensive replacement.

Despite his stellar defensive reputation, Heredia was relegated to corner outfield for all but one game of 2016 due to Leonys Martin’s stellar defense in center. Still, Heredia managed to make an impression. Heredia passed the eye test, and scored positively in both UZR/150 (+7.2) and DRS (+3). But what stood out most was his throwing arm. This throw made me a believer that among his many pretty good skills, he had at least one that was elite:

Petit out after challenge

He made an equally impressive throw this season to get George Springer trying to go from first to third, an out that proved pivotal in the Mariners securing a series win against the Astros:

Heredia nabs Springer at third

In just 705 innings in the outfield this season, Heredia has four outfield assists and +2.3 rating in the ARM component of UZR. His arm is an asset, and potentially one of the better throwing arms in the league.

Heredia’s scores in the range component of UZR were positive in 2016, and have been negative in 2017, for a total of -2.9 in 705 innings across three outfield positions. DRS is more favorable, giving him a +7 score across all three outfield positions, and exactly even at -1 in 251 innings in center. There’s no doubt he has the speed to play there, though his route efficiency is in question. Still, Heredia has nabbed 19 out-of-zone plays in center this season, and can outrun plenty of his poor jumps. Across all three outfield positions, he has scored +0.0 UZR, and +0.3 UZR/150. Even the most pessimistic evaluation of his defense would likely call him slightly below average in center.

If you’re someone that does hold the pessimistic outlook on his defense, then his bat would have to justify his playing time. The good news is Heredia now has a little more than two-thirds of a full season’s worth of plate appearances, and has steadily improved.

Heredia is hitting .271/.344/.368 (97 wRC+) in 450 career plate appearances, with a solid 14.5% strikeout rate, and decent 6.1% walk rate. He’s not riding an unsustainably high BABIP, either — his BABIP sits at .310, perfectly reasonable for someone with well above-average speed like Heredia.

In 34 games in the second half of 2017, Heredia has found a little more power: his first half ISO was just .091; it currently sits at .137 in the second half. Nine of his extra-base hits came in 208 plate appearances before the break, while 12 (11 doubles, 1 home run) have come after.

Even more encouraging is the fact that Heredia isn’t just a pull, or slap, hitter. Heredia’s career numbers split by where the ball is hit show that he can be effective hitting to any part of the field.

(Since walks aren’t put into play, this split is just AVG/SLG)

Pull: .333/.571
Center: .308/.342
Opposite: .323/.376

Essentially, Heredia only has power on his pull side, but can get on base hitting the ball in any direction.

There is one elephant in the room, though: despite his outstanding speed, Heredia just can’t steal bases. Perhaps he can learn how to get better jumps as he gains experience. It’s important to note that he missed his entire age-24 season trying to become eligible to sign with a team. But so far, Heredia has shown that he’s probably best utilizing his speed once the ball is put in play, rather than trying to advance via the steal. Between the minors and majors, Heredia has seven steals and has been caught 11 times.

Heredia can be an effective baserunner outside of when the ball is being pitched, though. He’s turned numerous singles into doubles by hustling out of the box, and shown that he can take two bases on a wild pitch If the catcher is lollygagging, as he did against Boston earlier this year:

Gamel scores on a wild pitch, ties the game

What the Mariners have in Heredia is a raw, speedy athlete with an absolute cannon for an arm, above-average on-base skills, and below-average, but developing, power. Heredia might never hit more than 10 home runs in a season. He might never steal more than 10 bases, either. But he’s amassed 1.2 WAR and posted a .344 OBP while playing at the very minimum passable defense in center field, with the upside for better.

He’s not Jarrod Dyson with the glove. He’s not Andrew McCutchen at the plate. What he is, though, is a competent offensive and defensive player with untapped potential. Even if he never improves, he looks capable of giving Seattle a 2-win center fielder going forward. Even a slight improvement could turn him into an above-average player, and one who is under team control for five more years.


MLB Dream Team: Active Players Bound for the Hall of Fame, Part II

In a continuation of my article from yesterday, here is part two of the MLB Dream Team. This article will showcase spots six through nine in the batting order as well as the starting pitcher.

Enjoy!

Batting sixth and playing second base…

Robinson Cano

64.4 career WAR / 50.3 7yr-peak WAR / 57.4 JAWS

Average HOF 2B:

69.4 career WAR / 44.5 7yr-peak WAR / 56.9 JAWS

9th in JAWS out of 20 Hall of Fame Second basemen

Accolades: 8x All-Star, 2x Gold Glove, 5x Silver Slugger, World Series Champion (2009)

For many years, Robinson Cano has been in the conversation as the best second baseman in baseball.

He was an integral part of the New York Yankees 2009 championship squad, and he parlayed his five All-Star appearances with the Bronx Bombers into a 10-year, $240-million contract with the Mariners in 2014. Cano hasn’t lost his luster since leaving New York for Seattle, and he has made three All-Star Games (so far) with the Mariners.

Cano had to beat out Chase Utley and Dustin Pedroia — two likely Hall of Famers in their own right — to earn his position at the keystone sack in this lineup. Ultimately, Cano received the nod because of his sustained excellence. He has played at least 156 games every year since 2007, a level of health that neither Pedroia nor Utley can match.

Cano has also redefined the second-base position because of his ability to hit for average and power. Among Hall of Fame second basemen, Cano’s average of 25 home runs per season ranks second and his 296 career home runs ranks third. In a few years Cano should hold the record for career long balls by a second baseman, and he should be known as the greatest power hitting second baseman of all time.

Batting seventh and playing center field…

Carlos Beltran

70.3 career WAR / 44.3 7yr-peak WAR / 57.3 JAWS

Average HOF CF:

71.2 career WAR / 44.6 7yr-peak WAR / 57.9 JAWS

8th in JAWS out of 19 Hall of Fame Center Fielders

Accolades: Rookie of the Year (1999), 9x All-Star, 3x Gold Glove, 2x Silver Slugger

Carlos Beltran, always a reliable asset, is now in his 20th season. Beltran has been every archetype an athlete can be: young star (Royals); decisive deadline acquisition (Astros); hero (Mets); scapegoat (Mets again); veteran contributor (Giants, Cardinals, Yankees, Rangers); and experienced old-timer (Astros again). Beltran was the fifth-youngest in the majors when he debuted in 1998, and now he’s the third-oldest player in the league.

Beltran came into the majors as a 21-year-old kid for the Kansas City Royals, and immediately showcased his skills by taking home Rookie of the Year honors.

After seven years in Kansas City, Beltran signed with the New York Mets in 2005. It was in New York that Beltran would spend the prime of his career, making five All-Star appearances and taking home three Gold Gloves. Beltran proved to be one of the best players in the Major Leagues from 2006 to 2008, crushing 37 homers, driving in 124 runs, and scoring 123 (per 162 games).

Beltran has aged well, making All-Star teams as members of the Giants, Cardinals, and Yankees since leaving the Mets in 2011. However, the 40-year-old has shown signs of decline this year, and he may decide to hang up his spikes in the near future. Beltran left a lasting impression on the game of baseball, and his 20 years of service deserve a place in Cooperstown.

Batting eighth and catching…

Joe Mauer

51.4 career WAR / 38.5 7yr-peak WAR / 45.0 JAWS

Average HOF C:

53.4 career WAR / 34.4 7yr-peak WAR / 43.9 JAWS

8th in JAWS out of 15 Hall of Fame Catchers

Accolades: MVP (2009), 6x All-Star, 3x Gold Glove, 5x Silver Slugger

Even though Joe Mauer has not caught a game since 2013, he spent 10 seasons and 920 games behind the dish.

Mauer was truly one of the finest offensive backstops ever, and in 2009 he became only the second catcher since 1980 to win MVP (Ivan Rodriguez was the first in 1999). In Mauer’s MVP season, he led the majors in batting average (.365) and on-base percentage (.444), both of which were records for catchers. He also led the AL in slugging (.587), OPS (1.031) and Offensive WAR (7.6). In addition to his MVP, Mauer was the first AL catcher to win the batting title and he holds the record for most batting titles by a catcher, with three.

As well as being one of the league’s finest hitters, Mauer was a force to be reckoned with behind the plate. His great instincts and fielding prowess earned him three straight Gold Gloves from 2008 to 2010, and his 99.51% career fielding percentage ranks seventh all-time among catchers.

Although Mauer’s body has declined over the years, he has performed well since being moved to first base in 2014, and has not made an error this year in 69 games.

Mauer will leave a legacy as one of the greatest hitting catchers ever, and he has earned his place in the Hall of Fame.

Batting ninth at shortstop…

Troy Tulowitzki

44.0 career WAR / 40.0 7yr-peak WAR / 42.0 JAWS

Average HOF SS:

66.7 career WAR / 42.8 7yr-peak WAR / 54.8 JAWS

26th in JAWS out of 21 Hall of Fame Shortstops

Accolades: 5x All-Star, 2x Gold Glove, 2x Silver Slugger

This is the hardest decision on the roster, because in my opinion there aren’t any Hall-of-Fame-worthy shortstops in the majors right now. Alex Rodriguez and Derek Jeter, the two best shortstops of this generation, have retired in the past two years.

I ended up choosing Troy Tulowitzki because he has the best chance of any shortstop in the majors to make it to the Hall.

There were a few ways I could have gone with this pick. At first I considered moving Chase Utley to short, and then I looked at the plethora of up-and-coming shortstops (Carlos Correa, Corey Seager, Francisco Lindor; to name a few).

Ultimately, I chose Tulowitzki — but this would have been a much easier decision if Tulo had stayed healthy during his career. During his prime years with the Rockies between 2007 and 2014, Tulowitzki averaged a respectable 4.8 WAR per season. However, he missed an average of 45 games per year (!) during that period. If you extrapolate his numbers to 154 games (meaning he would miss 8 games per year), he would have recorded 6.7 WAR per season, boosting his JAWS from 42.0 to 50.0.

Although Tulowitzki didn’t stay healthy most of the time, his impact while he was on the field was undoubted, and he deserves Hall of Fame consideration.

And your starting pitcher for tonight…

Clayton Kershaw

58.8 career WAR / 48.7 7yr-peak WAR / 53.8 JAWS

Average HOF P:

73.9 career WAR / 50.3 7yr-peak WAR / 62.1 JAWS

60th in JAWS out of 62 Hall of Fame Pitchers

Accolades: Pitching Triple Crown (2011), MVP (2014), 3x Cy Young (2011, 2013, 2014), 7x All-Star, 1x Gold Glove

Clayton Kershaw, in my opinion, is the best pitcher in the game right now. He has been terrorizing opposing hitters since coming up as a 20-year-old with the Dodgers in 2008.

Kershaw achieved the Pitching Triple Crown in 2011, when he led the league in ERA, wins, and strikeouts. In 2014, Kershaw joined Roger Clemens and Sandy Koufax as just the third player in baseball history to win three Cy Young awards and an MVP.

Kershaw has finished as an All-Star and a top-five Cy Young award finisher in each of the past six seasons, a nearly unparalleled run of dominance, and he has already attained a career’s worth of honors at just 29 years old.

Supposing Kershaw retires at age 37, he has eight years remaining in his career. If we extrapolate his season average of 5.7 WAR to seven more years, then his current WAR of 57.0 jumps to 102.6, which places him as the ninth best pitcher of all time, a very fair assessment.

Kershaw has the lowest career ERA of any starter since 1920* (2.35), and he deserves a plaque in Cooperstown.

*Baseball-Reference defines a starting pitcher as a player whose starts make up 60% of their appearances. Minimum of 50 Innings Pitched.

MLB Dream Team: Active Players Bound for the Hall of Fame, Part I

Sports always allow us to ask, what if? What if a baseball lineup — complete with all nine positions and a designated hitter — was composed of all-time greats in their best seasons.

I have composed a lineup filled with the very best active players who I think will make the Hall of Fame.

These players will not be judged on their performance this year; they will be chosen based on how well they performed during their primes.

I have designated a player’s “prime” as the best seven years of their career — not necessarily consecutive — and these selections are based on the player’s likelihood to make the Hall of Fame. Some members of the team will be inducted on the first ballot, and some will take years to make it to the Hall, but ultimately I think that every player on this list has a great shot at being immortalized in Cooperstown.

This article is part one of a two-part set in which I show my Dream Team. Part two will be released tomorrow.

Metrics Explained

Wins Above Replacement, or WAR, is the most commonly used advanced metric in baseball. It is a measure of how many wins a team gained by playing a specific player instead of a replacement player, who would have a WAR of 0. If a player records 2 WAR in a season, he is considered starting material, 4 or 5 WAR is acknowledged to be All-Star value, and 8 WAR is MVP-level production.

The Jaffe WAR score system, or JAWS, is simply the average of a player’s seven-year peak WAR and career WAR. For example, if a player had 100 career WAR and 50 seven-year peak WAR, his JAWS would be 75. This metric gives us perspective on how likely it is for a player to make the Hall of Fame compared to those who played their position.

Fielding Percentage is a measure off how often a player commits an error. For example, a fielding percentage of 97% means the player committed an error on 3% of the plays he made.

Note: This list favors older players because:

  • They have more career WAR
  • They have more years from which to choose their seven-year peak WAR
  • They are closer to entering the Hall of Fame than younger players.

Batting leadoff and playing right field…

Ichiro Suzuki

59.4 career WAR / 43.6 7yr-peak WAR / 51.5 JAWS

Average HOF RF:

73.2 career WAR / 43.0 7yr-peak WAR / 58.1 JAWS

17th in JAWS out of 24 Hall of Fame Right Fielders

Accolades: MVP (2001), Rookie of the Year (2001), 10x All-Star, 10x Gold glove, 3x Silver Slugger

Ichiro was one of the easiest selections for this Hall of Fame Dream Team. He was a trendsetter — the first Asian position player to debut in the Major Leagues.

In his rookie season, Ichiro set the baseball world ablaze, winning MVP and Rookie of the Year, and leading the league in hits, stolen bases, and batting average.

Ichiro was a revelation in the big leagues, and his game was predicated on speed not power, completely opposite to the direction baseball was trending. According to FanGraphs, Ichiro occupies the first seven spots on the list of highest single-season infield hit totals.

Ichiro was the hit king. He holds the records for most hits in a season (262) and most consecutive 200-hit seasons (10). He also tied the record for most 200-hit seasons (10), and led the league in hits seven times.

Recently, Ichiro reached the 3,000 hit plateau, and if you count his hits from his time in Japan, he broke Pete Rose’s record for most hits across all of baseball’s professional leagues.

In his prime, Ichiro was one of the best players in the world. Only Albert Pujols and Alex Rodriguez accumulated more WAR than Ichiro from 2001 to 2010. On top of being one of the greatest to ever play in the outfield, Ichiro was a cultural icon, and many of the recent advances that Asian players have made are attributable to him.

Batting second and playing left field…

Mike Trout

52.0 career WAR / 52.0 7yr-peak WAR / 52.0 JAWS

Average HOF CF (out of 19):

71.2 career WAR / 44.6 7yr-peak WAR / 57.9 JAWS

14th out of 19 Hall of Fame Center Fielders

Accolades: 2x MVP (2014, 2016), Rookie of the Year (2012), 6x All-Star, 5x Silver Slugger

Trout usually plays center field, but I had to move him over to left in order to accommodate him in the lineup.

Mike Trout is hands-down the best player in baseball right now, and is surely destined for Cooperstown.

Trout has only played five full seasons, but his numbers stack up well next to other center fielders who are enshrined in the Hall. And at just 25 years old, Trout is only entering his prime, meaning that his best years are ahead of him.

Now that’s a stunning thought.

Trout also has the sixth-best seven-year peak WAR out of the 24 center fielders in Cooperstown, in only five seasons!

Here I am talking about how Trout is a generational talent, and I haven’t even mentioned the countless honors that he has collected. Trout has made the All-Star team (for which he has won MVP twice), taken home a Silver Slugger, and been either MVP winner (twice) or runner-up (three times) in every season of his career.

That level of dominance is mind-boggling and completely unprecedented.

Batting third as the designated hitter…

Miguel Cabrera

70.0 career WAR / 44.6 7yr-peak WAR / 57.3 JAWS

Average HOF 1B:

66.4 career WAR / 42.7 7yr-peak WAR / 54.6 JAWS

10th in JAWS out of 20 Hall of Fame First Basemen

Accolades: Triple Crown (2013), 2x MVP (2012, 2013), 11x All-Star, 7x Silver Slugger, World Series Champion (2003)

Miguel Cabrera, still one of the best players in baseball, is a generational talent and already a surefire Hall of Famer. The Venezuelan has been tearing up the big leagues ever since debuting in 2003, and has brought a cheerful smile and a love of the game to wherever he plays.

In the beginning of his career, Cabrera was a young star on the Florida Marlins, one of the youngest teams in baseball. He experienced success early on when the Marlins won the World Series in his rookie year. Then, after a blockbuster trade to the Detroit Tigers in 2007, he continued to amaze in the American League.

From 2011 to 2015, Cabrera was the most feared hitter in all of baseball. During that time, he won four batting titles, took home two MVPs, and racked up five All-Star selections. In 2013, Cabrera captured the Triple Crown (leading the league in batting average, home runs, and RBIs), a feat that had not been accomplished since 1967.

Cabrera already has 2,598 hits and 458 home runs as of July 22nd, so he has a good chance to join Hank Aaron, Willie Mays, and Alex Rodriguez as the fourth member of the 3,000 hit and 600 home run club. Cabrera’s near-incomparable match of hitting for both power and average have vaulted him into the conversation as one of the best hitters of all time.

Batting cleanup and playing first base…

Albert Pujols

100.1 career WAR / 61.6 7yr-peak WAR / 80.8 JAWS

Average HOF 1B:

66.4 career WAR / 42.7 7yr-peak WAR / 54.6 JAWS

2nd in JAWS out of 20 Hall of Fame First Basemen

Accolades: 3x MVP (2005, 2008, 2009), Rookie of the Year (2001), 10x All-Star, 2x Gold Glove, 6x Silver Slugger,  World Series Champion (2006, 2011)

The easiest choice on the roster, Albert Pujols should make the Hall of Fame on the first ballot. Much like Pujols’ overflowing trophy cabinet, I don’t have room enough to praise Pujols, truly one of the greatest players ever.

Pujols has faded since he signed with the Angels on a 10-year, $240-million contract in 2012, but don’t let his struggles of late affect your judgement on his case for the Hall of Fame. He trails only Lou Gehrig in career WAR among first basemen, and is one of only 21 position players to record 100 career WAR.

Pujols’ nickname “The Machine” was an apt description of his time as a Cardinal. His 162-game average stats for his 11 years in St. Louis were: .328/.420/.617 with 127 RBIs, 123 runs, and 43 home runs. Pujols finished in the top 10 of the MVP voting all 11 years, ending up in the top five in ten seasons, and winning the award three times. But Pujols isn’t just a slugging first basemen, he is a very capable defender and has won two Gold Gloves.

Pujols became the ninth member of the 600 home run club earlier this year, and next year he should join the 3,000 hit club (as of July 22nd he has 2,908 hits). Pujols leaves a legacy as one of the best ever, and he deserves to be enshrined in Cooperstown.

Batting fifth and manning the hot corner…

Adrian Beltre

91.5 career WAR / 49.7 7yr-peak WAR / 70.6 JAWS

Average HOF 3B:

67.5 career WAR / 42.8 7yr-peak WAR / 55.2 JAWS

5th in JAWS out of 13 Hall of Fame Third Basemen

Accolades: 4x All-Star, 5x Gold Glove, 4x Silver Slugger

Adrian Beltre, still chugging along at the ripe age of 38, has graced baseball with his presence for 20 seasons. From hitting home runs off one knee, to his aversion of people touching his head, Beltre is one of the true characters of the game.

Beltre is third all-time in WAR among third basemen, trailing only Mike Schmidt and Eddie Mathews. He also figures to be the next member of the 3,000 hit club, needing only 15 more hits as of July 22nd. And if he decides to come back and play next year, he has a great chance of overtaking Brooks Robinson for most games played at third base.

Those are just some of the records that Beltre is approaching, and he does not seem to be slowing down.

There is just no debate on Beltre’s Hall of Fame candidacy. Among all third basemen, he ranks in the top five in games played, hits, doubles, home runs, RBIs, and WAR.

Beltre’s legacy will be as one of the best defensive third basemen of all time, and he trails only Brooks Robinson in Defensive WAR among players who have manned the hot corner. His highlight reel of diving stabs, barehanded picks, and throws from all the way across the diamond make him one of the best ever to play third base.

Special thanks to baseball-reference.com for all of these helpful stats. I could not have written this article without them.

Thanks for reading Part I. Part II will be released at a later date and it will include spots 6-9 in the batting order as well as the starting pitcher.

To be continued…


Exploring Uncharted Territory with Leonys Martin

Edit: Since this piece was submitted (May 23), several developments in the Martin narrative have arisen, notably some more astute analyses than mine (namely Jeff Sullivan’s great piece on Martin’s batted-ball profile & an extremely in-depth look at his swing mechanics by Jason Churchill over at ProspectInsider, do go check him out) as well as this walk-off dinger against the Oakland A’s. 

 

A lot has gone right for the Seattle Mariners in new GM Jerry Dipoto’s first season. At time of writing, they sit in first place in the AL West with the third-best record in the American League and the best road record in baseball. One potential factor in Seattle’s success that has, until recently, taken a backseat to Robinson Canó‘s resurgence and Dae-Ho Lee’s power-hitting heroics is the sudden onset of what could turn out to be an offensive breakthrough for outfielder Leonys Martin.

The Mariners’ acquisition of Martin and Anthony Bass in exchange for Tom Wilhelmsen, James Jones, and a PTBNL (Patrick Kivlehan) is one of several moves last offseason that seem to follow a common guiding principle: bring in players who’ve struggled in recent seasons but demonstrated real value in seasons past. This category includes the likes of Steve Cishek and Chris Iannetta, both of whom seem to have (thus far) rebounded from uninspiring 2015 campaigns.

Meanwhile, Leonys Martin is having the best season of his life. This is mostly remarkable due to the fact that his hitting isn’t, and has never really been, the source of his value. He’s never topped 89 wRC+ in any season, and his career high for home runs in a year is eight. He’s also been historically abysmal against left-handed pitching. From 2012-15, Martin slashed .233/.274/.298 with 53 wRC+ against southpaws; no outfielder in baseball posted fewer wRC+ in that same span (min. 300 PAs). His poor performance in the second half of 2015 (.190/.260/.190 with 22 wRC+ after the All-Star break) earned him a demotion in early August. That lackluster second half, coupled with the emergence of Delino Deshields Jr. as a capable replacement, made it a lot easier for the Rangers to part with him in the offseason (incidentally, DeShields was demoted in early May and Wilhelmsen has been the worst reliever in the majors this year by fWAR, so that’s something).

Going into this season, Steamer projected him for around 492 PA with a .241/.292/.350 slash line and 79 wRC+, in addition to eight homers and 22 stolen bases, putting him on course for 1.2 fWAR. While not exceptional, this likely would have been an adequate season for Jerry Dipoto given the cost, especially at Martin’s $4,150,000 salary, but Martin’s already managed to match that mark, posting 1.4 fWAR as of May 23rd, and he’s providing a great deal of that value with his bat.

Martin seems to have shook off a bit of whatever seemed to be plaguing him at the tail end of 2015. He’s slashing .252/.331/.467, which would, over a full season, leave him with a career-best OPS of .798 and 124 wRC+. He still hasn’t been able to hit lefties, but that’s what platooning is for. But by far the most eye-popping aspect of Martin’s game this year is what looks like a sudden influx of power. Martin’s mark of .215 ISO is easily the best of his career — his eight home runs have already matched his career-best single-season total — and it’s not even June yet. With no context, one could look at Martin’s line thus far and notice that he might be on pace to post a 30 HR/30 SB season, if not for the slight inconvenience called “At No Point In His Career Has Martin Demonstrated That He Might Even Touch 30/30”. And yet this is baseball, and this is 2016, the Year of the Bartolo Colón Home Run. Anything is possible.

So — what’s changed for Martin? And perhaps more importantly, where the heck did all these home runs come from?

We turn first to Martin’s batted-ball profile. For the last two-and-some seasons, Martin’s fly-ball percentage has actually increased. His 2015 mark of 33% was actually a career-best at the time, especially considering it was brought down by his abysmal second half. He’s picked it back up in 2016, with a gaudy 45% fly-ball rate. Of course, the sustainability of this figure is questionable (one might also point out Martin’s likely inflated HR/FB rate of 20.5% — opposed to a current league average of 12.1%), but at no point in his career has Martin hit fly balls with such consistency:

Other indicators of improved power add credence to this positive trend. Martin’s quality of contact also seems to have improved this year, as his hard-hit ball rate of 34.4% is vastly superior to his pre-2016 range of about 23 – 25%. It’s also true that home/road splits affect the narrative somewhat, as only one of his eight home runs occurred at Safeco Field. But I suspect that there may be more to Martin’s offensive resurgence than just hitting balls harder.

One of the feel-good narratives of this season is the positive influence that new hitting coach Edgar Martínez has introduced to the Mariners offense, which currently ranks 2nd in the AL in runs scored. Martinez was brought in to replace Howard Johnson in June 2015, hoping to fix an anemic Mariners offense that struggled early and often. To date, that new appointment has been received with praise from Seattle media and fans, but more importantly from the players themselves. Could it perhaps be the case that Edgar’s tutelage, along with Jerry Dipoto’s promise to mold the 2016 Mariners to fit his “Control the Zone” philosophy, has brought about a positive change in the way Leonys Martin approaches hitting?

Overall, Martin’s plate discipline metrics show that his approach at the plate hasn’t changed too drastically from last season. If anything, his 70.4% contact rate is his lowest since 2012. One other thing sticks out here, namely that Martin seems to be more patient on pitches out of the zone and more aggressive on pitches in the zone. Compare the percentage of pitches he swings at in 2015 (left) to 2016 (right), courtesy of BrooksBaseball.net:

There is a relatively noticeable difference here, especially on high and outside pitches. According to PITCHf/x, his O-Swing% of 27.9 is easily the lowest of his career. Likewise, his Z-Swing% of 67.0 is his highest since 2012. These are generally good indicators that Martin is seeing the ball better or, at least, cut down on his tendency to chase pitches out of the zone.

And then there’s the matter of his batting stance.

Take a look at his stance for this home run on May 27, 2015, facing off against Scott Atchison:

Now check out his stance almost a year later, on May 22, 2016 in this at-bat against John Lamb.

An important thing to note about these stills is that I picked them mostly because of their similar camera angles. Martin’s foot position in other highlights is often obscured by the pitcher, or the pitcher is already in the middle of his wind-up, giving Martin time to square up before the pitcher’s delivery (as is slightly apparent in the at-bat against Lamb). But the vast majority of video evidence from this season is consistent with the idea that Martin has generally closed off his stance and now begins pretty much every at-bat with his feet squared to the pitcher. Now, I am aware that the batting stance is a rather fluid component of any baseball player’s oeuvre and can change for a number of reasons, not all of them being deliberately engineered to improve performance. I can’t seem to find anything about Martin having changed his stance online, aside from this ESPN piece from February of this year — but the focus of that article is on a legal issue Martin dealt with over the offseason, and the only comments offered on Martin’s approach seem to indicate that his stance hadn’t actually changed:

Martin also worked with a hitting instructor during the offseason in Miami. He altered his approach at the plate — his stance remains the same, he said — and he was pleased with the results when he faced pitchers in winter ball.

The most significant changes I’ve noticed as a result of comparing film from 2015 to film from 2016 are the aforementioned foot positioning and the fact that his hands are a little bit closer to his body this year. Generally speaking, though, it’s hard to really quantify the connection between a player’s stance and his performance. If this change in stance is deliberate, we can only really speculate as to the reasoning behind it. There are certainly good reasons to make the adjustments Martin has made. Bringing the hands closer to the body is often a nice starting point for a player who wants to make his swing a little more compact and less erratic. As for the foot positioning, there are a few benefits to batting with an open stance, especially for a left-handed hitter. One is that it enables left-handed hitters to see the ball better, especially when facing a left-handed pitcher. Another is that it eliminates the problem of the front foot stepping away from the plate on the swing, as batting from an open stance requires you to bring your front foot towards the plate in order to square up to hit the ball. It’s hard to say if Martin has previously had this issue in the past, but the fact that he’s changed from an open stance to a square stance likely indicates to me that whatever advantage he gained from an open stance may no longer be necessary. We don’t know if Martin has made these adjustments for the reasons listed above or if he has made them for any real reason at all, but he’s still made them all the same, and as it happens, they’ve been working out quite nicely for him.

That said, let’s not go overboard about a quarter-season of statistics just yet. Though Martin is posting career bests in almost any meaningful batting metric, there is still reason to believe he might still turn out to be an average or below-average hitter for the rest of the season. His on-base record is rather inflated by recent performances, he strikes out too much, and he continues to sport uninspiring numbers against left-handed pitching. All the same, his eight home runs this season aren’t going away, even if his fly-ball rate might. It’s unlikely, barring injury, that he’s not going to hit any more home runs for the rest of the year, so 2016 will most likely be a career year for him in the power department, and if his BABIP mark of .302 this year can regress back to his 2013-14 average of .326 rather than his poor 2015 mark of .270, 2016 may turn out to be a career year for him across the board. Martin’s offensive production has certainly been a pleasant surprise for the Mariners, and it would be interesting to know if altering his batting stance was a deliberate factor in producing an improved approach at the plate. If the Leonys Martin we’ve seen so far this year is anything like the Leonys Martin we’re going to see for the rest of the year, Jerry Dipoto may have stumbled upon a surprisingly high return on what was initially a low principal investment.


The Mariners are Finally Using Safeco Field Correctly

It’s no trade secret that playing to the strengths of your ballpark helps your chances to succeed. To gain an advantage, franchises can exploit, and even sometimes manipulate their home ballpark. If you run the Astros or Reds, who play baseball in a lunchbox, you can succeed by employing otherwise-flawed home-run hitters with little regard for who gets on base ahead of them. When you play half your games in an airplane hangar, however, stubbornly attempting to put the ball over 900 foot fences is foolish. A foolish strategy common of recent Mariners teams. A foolish strategy that wasn’t working.

The Mariners wrote the Greatest Hits on failing to get on base and, not surprisingly, struggled to win games during those seasons. For years and years, the Mariners tried succeeding with players like Logan Morrison, Michael Morse, and Mark Trumbo, desperately clinging to the home run as the heralded harbinger of scoring runs. Whether this was evidence of a failing regime by general manager Jack Zduriencik remains up for debate, but the front office had seen enough. Around the same time, a wayward GM separated cleanly from the Mariners division rival Angels was seeking asylum, armed with his own vision of building a team.

Strategy 1: Get on Base

Jerry Dipoto, presumably having read Moneyball, understood the value of getting baserunners, and how to get players on base.

“Command the Strike zone” Dipoto told Justin Myers and Gee Scott on their ESPN 710 Seattle radio segment. “From the top of the lineup to the bottom, we will command the strike zone”.

Dipoto began addressing the team’s glaring need for baserunners by signing catcher Chris Iannetta, who had played for Dipoto in Anaheim, and had posted OBP numbers over .350 in 2011, 2013 and 2014. Dipoto found further help by trading for Adam Lind (.350 OBP in 2015) and  signing free agent Norichika Aoki (.353 OBP in 2015, 6.4 K%).

None of these moves were meant to be earth-shattering, but each undoubtedly made the Mariners lineup better. With a solid core of Robinson Cano, Nelson Cruz, and Kyle Seager, Dipoto’s goal was to fill the remaining slots with valuable role players, each of whom is more than capable of getting on base.

Here is a table of several key Mariners offseason additions, with 2015 statistics, and 2016 ZIPS projections courtesy of Dan Szymborski. Note that season projections are often more conservative estimates, as they account for a certain level of player regression.

OBP (2015, 2016) wOBA (2015, 2016) BB% (2015, 2016) K% (2015, 2016)
Chris Iannetta .293 .281 12.9 26.2
.329 .306 14.0 25.8
Adam Lind .360 .351 11.5 17.5
.334 .315 10.1 19.5
Nori Aoki .353 .326 7.7 6.4
.332 .313 7.0 7.8

Strategy 2: Prevent runs, Create runs

Dipoto, addressing the fallbacks of that revolutionary A’s season, also understood the value of defense and speed. “We see ourselves as a run-prevention club. You can create a lot of advantage playing good defense. We also see our overall team defense as our biggest area in need of improvement.”

Dipoto went primarily after well-rounded players, but several moves in particular focused on defense and speed. In November, Dipoto traded closer Tom Wilhelmsen to Texas in exchange for Leonys Martin, a light-hitting center fielder with blazing speed. Martin didn’t quite play enough innings (334) in 2015 to qualify for the CF leaderboard, but his 15.4 Ultimate Zone Rating/150 would have ranked him 5th best among MLB center fielders, just above Lorenzo Cain. Martin, by the FanGraphs arm strength statistic, also had the strongest arm of any center fielder in baseball.

In terms of speed, Martin is as fast as they come. He’s been consistently valuable on the basepaths, posting a 4.3 and 4.2 BRR in 2014 and 2013 respectively (BRR is Baseball Prospectus’s baserunning statistic, where 0 represents an average baserunner). Martin posted a lower total BRR in 2015 (1.5), mostly because his on-base percentage dropped 61 points from 2014, and he appeared at the plate 273 fewer times (generally it’s harder to be a valuable baserunner if you don’t get on base as often).

The second move was to acquire Boog Powell, young center field prospect, from Tampa Bay. Powell was part of a larger trade, wherein Seattle received starting pitcher Nate Karns and Powell, and sent Logan Morrison and shortstop Brad Miller to the Rays. We’ll talk about Karns in the last section, but Powell further embodies Dipoto’s vision of commanding the strike zone, getting on base, and playing defense.

Powell’s defensive statistics are less clear than Martin’s, since Powell has never stepped foot in the major leagues, but he’s consistently graded out in the minor leagues as a plus defender. Powell is 22, and serves as outfield depth should Martin fall down a well in center field.

It’s clear that Dipoto aggressively wanted to improve the outfield defense. In his wild spree of moves, he also made his infield defense better. In trading for Lind, he incrementally made first base a more well-defended position (Lind posted a 3.8 UZR in 2015, compared to Logan Morrison’s -2.9). Brad Miller was a plus defensive shortstop (1.1 UZR, 4.6 dWAR), but with the emergence of talented, young Ketel Marte (1.2 UZR, 2.8 dWAR in 310 fewer innings at SS), Dipoto knew he could afford to trade Miller.

If one looks around at the Mariners in the field, Robinson Cano and Nelson Cruz are currently the only remaining defensive liabilities, and Cruz might not see much right-field time this year. Kyle Seager is a plus defender, Aoki is capable in left, and Seth Smith improved his defense dramatically last season. The team re-signed Franklin Guitierrez (3.4 UZR, 1.9 dWAR) to split Right Field with Smith and Cruz. At the catcher position, both Iannetta and Mike Zunino are among the 10 best pitch framers in baseball, saving an aggregate 26.8 runs in 2015.

The Mariners were the 5th worst defensive team in 2015, but that looks likely to improve in 2016.

Strategy 3: Taking advantage of Dinger-hitting tendencies

When you play baseball in an extreme pitcher-friendly park, in a sea-level city whose summer nights are cool and humid, home runs are a rare commodity. The Mariners understand they won’t win by hitting home runs, but they also understand that the same difficulty exists for opposing teams. Thus, the Mariners can fill their starting rotation with pitchers with higher than average fly-ball rates. Here are the totals from Mariners starters in 2015. WARP is Baseball Prospectus’s cumulative wins above replacement player statistic.

IP FB % GB% BABIP WARP
Felix Hernandez 201.2 26.9 56.2 .288 3.3
Taijuan Walker 169.2 39.0 38.6 .291 1.8
Hisashi Iwakuma 129.2 31.1 50.3 .271 2.5
James Paxton 67.0 34.4 48.3 .289 0.0
Roenis Elias 115.1 36.4 44.2 .280 0.9

Normally we’d expect a higher GB rate to correlate with a higher BABIP, since it’s more likely for ground balls to find holes and become hits than it is for fly balls. Felix has the highest GB rate of that table, and still maintained a better-than-average BABIP. That’s because he’s Felix Hernandez, and he’s better than you. Iwakuma, 34, also posted a ground-ball rate of 50%, and he’s never posted a BABIP above .287. After 2000 balls in play, a pitchers BABIP will normalize, and Iwakuma is quickly approaching that. Walker has the highest FB rate, so it’s probably good that he pitches where he does.

Before you even get beyond the innings pitched column, however, it’s clear the Mariners were thin on reliable starting pitching depth in 2015. Out of the players above, only Hernandez and Walker eclipsed 130 innings, only those two and Iwakuma provided any sort of positive contribution, and Roenis Elias is now on the Red Sox.  So the offseason began, and Dipoto got to work.

Earlier we mentioned Boog Powell becoming a Mariner, but he came over as secondary piece that landed the team starting pitcher Nate Karns from Tampa Bay. Karns had a quasi-breakout season in 2015, posting a 3.67 ERA and 3.90 xFIP in 147.2 innings pitched (xFIP is a Fielding Independent Pitching statistic that takes fly-ball rate into account). This was the first full season for the 27-year-old Karns, who also had a 36.5% fly-ball rate in 2015. Of those fly balls, 12.5% went for home runs, an above-average rate for a starting pitcher. While Tropicana Field is not an especially friendly ballpark for hitters, every other park in the AL East dramatically favors home runs, and Karns’s HR rate was likely hurt by pitching frequently at parks like Yankee Stadium and Camden Yards.

Karns should be aided by the expansive parks of the American League West, where more fly balls will become outs. If Karns matches, or even exceeds his peripherals in 2016, while maintaining his high fly-ball rate (fly-ball rate normalizes after 70 fly balls, a total Karns exceeded long ago), he should lower his home-run rate, and his BABIP. Karns also has room for regression, as HR/FB doesn’t normalize until after about 500 IP.

There is a question of Karns’s durability, having only one major-league season with over 100 innings pitched, but no such question exists with Dipoto’s next trade target. A month after grabbing Karns, Dipoto traded Elias and closer Carson Smith to Boston for Wade Miley, one of the most consistently durable left-handed starters in the game. Smith was a bright spot in a bad Mariners bullpen, so Dipoto had to give up some value to acquire Miley, but the GM took that risk to bolster a shaky rotation. Miley has pitched more than 190 innings in four consecutive seasons: 2015 in Boston, and the previous three in Arizona. All of those years have featured FIPs below 4, and improvements across many categories in 2015, lowering his home run/9 rate by .24 despite pitching in the AL East. It’s no stretch of the imagination for Miley to improve even further in 2016, playing in front of an overhauled Mariners defense.

Miley and Karns, 2015 Statistics
Name            IP          FB%          GB%        BABIP        WARP
Nate Karns           147         36.5          41.9          .285            1.6
Wade Miley          193.2         30.5          48.8          .307            2.5

You start to see how exploiting these park advantages becomes mutually beneficial. A speedy outfield defense will turn more of Nate Karns’ fly balls into outs, and a more solid infield defense will help turn Miley’s ground-ball hits into outs as well. On the offensive side, players who don’t strike out will put the ball in play more often, and the increased speed of the lineup will turn more of those balls in play into hits, increasing the number of baserunners. If, with all of these improvements, we still believe in Nelson Cruz’s power, Kyle Seager’s upward trajectory, and continued King Felix domination, we believe in Mariners success.


The Mariners Need to Help Robinson Cano Help Himself

The struggles of Robinson Cano in 2015 have been talked about frequently, especially as the Mariners’ struggles continue. Recently, Mariners hitting coach Howard Johnson suggested that Cano is pressing at the plate. Cano disagreed with the assessment, but the numbers back up Johnson.

The good news is that when Robinson Cano is making contact, it’s been pretty good. Cano is hitting the ball harder than he has over his career. His hard hit percentage is 35.2%, compared to his career 32.9% mark.  The 24.4% of line drives on batted balls would be the third highest mark of his career, exceeding his 21.4% career average.

The bad news is where Cano is hitting the ball.  Cano is hitting out of character. In particular, Cano has had some difficulty, or aversion, to hitting the ball to the opposite field. The chart below shows Cano’s 2015 batted-ball locations and his career batted-ball locations.

Contact Location Pull% Cent% Oppo%
2015 38.6% 42.0% 19.3%
Career 37.5% 35.7% 26.8%

This is a big issue because he is muting his best hitting ability. Cano is a .369 hitter when hitting the ball to the opposite field. Last year he hit .417 when going the opposite way; in 2013 he hit .455. This year he is hitting .303, but he is not giving himself the opportunities to take advantage of the success that has been consistent throughout his career and stellar in his most recent seasons.

The impact of this shift can be displayed by taking Cano’s 174 plate appearances in which he has not walked or struck out, and allocating the results of where the ball is hit by his career average Pull%, Center%, and Oppo%. I then applied his career batting averages for the batted ball location to those figures.

Batted Ball Location Career Batted Ball Location Averages Batted Ball  Location At Bats Ending in Batted Ball Loaction Career Batting Average in Batted Ball Location Projected Hits in Batted Ball Location
Pull 37.5% Pull 65 .327 21
Center 35.7% Center 62 .370 23
Opposite 26.8% Opposite 47 .369 17

The following would be the resulting average on batted balls, batting average, and on-base percentage based upon Cano’s 40 strikeouts and 12 walks:

Average on Batted Balls 0.354
Batting Average 0.290
On Base Percentage 0.327

These numbers are good, but they are still not remarkable, and they don’t look like the numbers we would expect from Cano.

This leads to Cano’s second issue: increased strikeouts. Cano’s 17.5% strikeout rate is well above his career average of 11.2%.

The Baseball Info Solutions Plate Discipline data shows two figures that stand out. (1) Cano’s Contact% is down 3.9% from his career average and (2) Cano is seeing 5.4% more first-pitch strikes than he has over his career.

Contact% F-Strike%
2015 82.7% 65.9%
Career 86.8% 60.5%

Lets start with the second figure. This is nothing Cano has control over and the cause is almost certain to be the presence of Nelson Cruz behind him in the lineup. But how can Cano adjust to this? He’s a batter that’s used to being pitched carefully, particularly last year, when he was a hitting oasis in the desert that was the Mariners’ lineup.

The first figure, Cano’s drop in Contact%, may be tied back to where this article started and the point mentioned above: hitting approach and batting count. Cano has performed pitifully when facing sliders and changeups this year, two pitches he has handled well over his career (see the chart below displaying Baseball Info Solution’s runs above average/100 pitches for each pitch type Cano has faced). This makes sense if he is seeing pitches behind in the count, and if he is aggressively seeking to pull the ball, for additional power; to be worth $24 million a year, or whatever reason that may be causing the change in hitting approach.

wFB/C wSL/C wCT/C wCB/C wCH/C wSF/C wKN/C
2015 -0.44 -1.71 -1.46 1.92 -4.07 3.67 -4.66
Career 0.65 1.58 -0.3 1.65 1.65 1.65 0.66

Howard Johnson is probably right. Robinson Cano is pressing. Cano needs to approach at-bats like he has his whole career and he’ll see a return to what we would expect from Robinson Cano. However, the Mariners can make it easier on him by changing up the order. Maybe Cano isn’t a hitter that thrives on being pitched to. It may benefit the Mariners to swap Cruz and Cano in the order. While Cruz has been great, the Mariners and Cano have been the opposite. A change couldn’t hurt.

But first, Robinson Cano needs to accept the hitter he is, because that hitter is very good.
