The Boston Red Sox almost romantic approach to the plate has been one of the major themes on their journey to be the first team with 60 wins. Last night’s expose of producing home runs and precise batting behind Chris Sale’s robotic approach to pitching gave the Red Sox a 10-5 victory over Kansas City Royals for their 60^th victory; another notch in a long-chain of accomplishments. More impressively, however, is the Red Sox micro approach to each game. They have not only revolutionized the average statistics played out through the tenure of a season but have revolutionized how they approach the plate inning-by-inning. The romantic plate approach is more than good batting – it is the beginning to a methodical introspection into opposing pitchers for an evolution in innings five and six.

In an interview with 710 ESPN Seattle’s Danny, Dave, and Moore, Seattle Mariners pitcher Marco Gonzales casually remarked of his struggles against the Red Sox on June 24 that they were “taking swings we haven’t seen before.” Gonzales lasted only six innings against the Red Sox, allowing seven hits and five runs on six strikeouts. The fifth inning was the instant the game changed in the Red Sox favor as they scored three.

Naturally, this observation may have been a microcosm dependent on Gonzales’ pitching, not so much the Red Sox. Yet, the observation was enticing enough to warrant investigation. The results were incredible, explaining why the Red Sox meta of plate patience is about more than being disciplined – they pedantically study batters through the first few innings, leading to innings five and six which are destructive.

Before delving into the data, two notations must be established. First, the Red Sox are, on average, destructive regardless of the inning. Their jump in innings five and six are not why they are good, but why the are atop the MLB this year. Second, analytic rise in statistics in innings five and six is a trend across the league; it might be easy to pass on the Red Sox rise as the best batters popping off on ‘third-time through the rotation’ deterioration. Again, however, the Red Sox are using the seemingly inevitable deterioration of pitchers throughout the game and exacerbating on that analytic.

Within innings one through three, the Red Sox hold a .270 batting average with a 20.5 percent strikeout rate, an 8.4 percent walk rate, a .467 SLG, and a 117 wRC+ – all rates which make the Red Sox a top MLB team intrinsically. Stopping here, the Red Sox would be a good team alone. However, as mentioned, the Red Sox jump to great in inning five and six. They post a .292 batting average, only 15.7 percent strikeouts, 7.9 percent walks, a .538 SLG (.240 ISO!), and a wRC+ of 139.

On a micro-level, the functional output has benefited Mitch Moreland and Mookie Betts the most; Moreland has a .808 SLG and Betts has a 234 wRC+. Even Rafeal Devers has a sharp increase in effectiveness in these innings, raising his egregious .198 average from innings one through three to a .304 average in innings five and six.

Mechanically, the Red Sox, as a team, change the type of pitches they attack. Produced from Baseball Savant, here is a graphic of the pitch movement attacked in innings one through three; here is the comparative graphic for innings five and six. The graphic shows most of the pitches they take at the beginning of the game have little horizontal movement and trend with more vertical movement – hence, pitches which are easier to see. As the game goes on, they dramatically increase their SLG by attacking pitches with sharp horizontal movement, even hitting low.

In application, it might be said the Red Sox study through the first few innings, waiting to see how pitchers will attack under the guise of movement. Their contact is more studied through this span, evidenced by J.D. Martinez’s expected SLG of .936, Bett’s of .843, and Andrew Benintendi’s of .757. Even Devers sees an increase from an xSLG of .389 to .545.

The Red Sox plate discipline is purposed, thoughtful, and intended for the length of a game and season. They literally improve the quality of swings and contact throughout the game; the maxim of why analytical discipline is important to success.

The Red Sox’s third-base problem was not solved by a veteran rental. No, it was solved by a sweet-hitting 20-year-old Dominican named Rafael Devers.

But before I explain Devers’ spectacular rise, I must set the stage for his entrance.

~~July 24th~~

It’s July 24th and the Red Sox have ground to a halt. Baseball’s non-waiver trade deadline is just eight days away and nearly the entire baseball community expects the Sox to trade for Todd Frazier.

Frazier, the third baseman for the White Sox, is in the midst of the worst season of his career. He’s hitting just .210 and his contract expires at the end of the year.

The Red Sox haven’t been able to gain traction since the All-Star break, going just 5-6. The Yankees, their ever-present rivals, are creeping up on them in the standings and have swooped in on a trade for Todd Frazier, even though many executives and analysts were sure the slugger would join the Red Sox.

Third base has been a huge issue for Boston, who has used eight (!) different players there. Collectively, Red Sox third basemen are slashing .227/.280/.320, marks that rank 27th, 29th, and 30th in the league, respectively. They have not only been terrible hitters, but they also lead the league in errors.

Dave Dombrowski decides to rectify the Red Sox’ third base issue by promoting top prospect Rafael Devers to the big leagues.

~~A Rafael Devers Profile~~

Rafael Devers was born on October 24th, 1996 in Sanchez, an aging port city in the Dominican Republic. He first started playing baseball at the age of five, inspired by his father, who played amateur ball. Devers grew up with baseball all around him and quickly showed immense talent.

In 2013, Devers signed with the Red Sox at just 17 years old. He was ranked as the number three international prospect in his class, and he signed with the Red Sox, his childhood favorite team, for $1.5 million. Devers entered the Red Sox organization as their 20th ranked prospect in a deep farm system.

Upon joining the Red Sox, Devers was placed in the Dominican Summer League (DSL), a place where new international signings go to work on their skills. Devers took the DSL by storm, batting .337/.445/.538 with three home runs in 28 games. He impressed everyone, by his ability to hit for both average and power, and also by his great batting eye — Devers walked more times than he struck out.

After tearing up the Dominican League, Devers was sent to the States, where he played in the Gulf Coast League. The Gulf Coast League, or GCL, is where first-year minor-league players are sent after being drafted or signed by their teams. Most of the players in the GCL have been drafted out of college or have just finished high school, meaning that at age 17, Devers was one of the youngest players in the league. Devers carved up the GCL, batting .312 with 11 doubles and four homers in 42 games.

After Devers’ wildly successful first year, he was rated as the Red Sox’ sixth-best prospect, and baseball’s 99th-best, all at just 18 years old. This was an incredible accomplishment, as Devers was the youngest player on Baseball America’s top-100 list that year.

In 2015, Devers was promoted to the Red Sox’ Low-A affiliate, the Greenville Drive, where he experienced full-season ball for the first time. There, he was matched up against much older opponents, being one of just seven position players under the age of 19 in the South Atlantic League. Devers played well in Greenville too, batting .288 with 38 doubles and 11 home runs in 115 games. During the 2015 season, Devers was selected to the Futures Game, an event during All-Star weekend that showcases baseball’s best young talent. After a season in Low-A, Devers was ranked as Boston’s second-best prospect, and baseball’s 18th-best. Devers jumped 81 spots on Baseball America’s top-100 in just one year, a remarkable achievement.

In 2016, Devers was promoted to the Red Sox’ High-A affiliate, the Salem Red Sox, at the age of 19. However, Devers hit a bump in the road in Salem. Among players much older than him, it appeared that Devers had finally met his match. In the first half of the season, he scuffled to a .233/.300/.305 line with just four home runs in 63 games.

However, Devers bounced back brilliantly after the All-Star break. He slashed an incredible .326/.367/.539, with seven home runs and 11 steals in 64 games. After this second-half breakout, Devers has not looked back in his meteoric rise to the majors.

In 2016, Devers’ defense finally started to catch up with his offense. Early on in his career, scouts considered moving him to first base, because of his heavy build. But Devers has worked hard on his defense, and has stayed at the hot corner. In High-A, Devers led all Carolina league third basemen in fielding percentage (.960), putouts (104), and assists (258).

After his outstanding second half in High-A, Devers earned a non-roster invitation to 2017 spring training with the Red Sox. This was a big step up for the 20-year-old Devers, but he wasn’t ready for it, batting 3 for 22 against big-league competition. Nevertheless, he earned a promotion to Double-A Portland, where he played for most of this year.

Devers was the Portland Red Sox’ standout player this year, socking 18 homers in addition to achieving an excellent .296/.366/.571 slash line. In 77 games, Devers jumped to number six in Baseball America’s most recent prospect rankings. He was also selected to participate in the MLB Futures Game for the second time.

Devers was promoted to Triple-A on July 14th, and continued to hit for both average and power while in Pawtucket. Devers became the third-youngest player ever to be promoted by the Red Sox to Triple-A, yet another reminder that he was playing extremely well for his age. The Dominican lefty hit an astounding .400 for the Pawtucket Red Sox, and he earned a promotion to the big leagues after just nine games in Triple-A.

When Devers debuted on July 25th, he was the youngest player in the major leagues, but you’d never know it. His first major-league hit was a home run (!), and during his 16 career major-league games, Devers has surprised everyone.

Scouting report

Devers has a very promising future, thanks to his ability to hit for both average and power. He has incredible raw power, and can spray the ball to all fields. His opposite-field power is unsurpassed among players his age. For example, when Devers hit two homers against the Indians on August 14th; one was a laser into the Green Monster seats in left field, and the other was a high drive into the Red Sox bullpen in right field.

Devers also has great bat speed, and he is able to hit pitches very far, and to any part of the field. On August 13th, Devers hit a 102.8 mph pitch into the Yankees bullpen, the fastest pitch ever hit for a home run in the pitch-tracking era.

Devers is not as polished as other recent Red Sox prospects like Andrew Benintendi, but he has a higher ceiling. I project that in his prime years he will hit around .285 with 30 home runs, 40 doubles, and five to ten stolen bases.

He has improved his defensive skills, but don’t expect him to be a Gold Glove-winning third baseman. I believe he will stay at the hot corner, as he is becoming more reliable and is improving his range. Overall, Devers projects to be an All-Star with a dependable glove and a reliable, middle-of-the-order bat.

Conclusion

As of August 15th, Devers is hitting .339 with six home runs, incredible statistics that show his ability is way beyond his years. I don’t mean to read too closely into Devers’ 62 career at-bats, but he has a very promising future.

Pairing Devers with other young Red Sox stars like Mookie Betts, Jackie Bradley jr. and Xander Bogaerts should help Boston stay at the top of the AL East for years. Devers gives Boston an entirely homegrown lineup, the dream of every major-league team.

With less than one month to go, the American League MVP race is very close. While usually nothing is set on stone in early September, during the last few years the AL MVP has been a two-man race (Mike Trout with either Josh Donaldson or Miguel Cabrera). This year, however, features five remarkable candidates: Mookie Betts, David Ortiz, Jose Altuve, Mike Trout and Josh Donaldson. Yes, I expect a few other to grab a few top-five votes (e.g. Cano, Cabrera, Lindor and Machado) but I don’t anticipate the award to fall outside those five players.

Let’s look at the classic, old-school numbers first, which not only are sometimes referenced in casual conversations at local bars and pubs but also frequently (and occasionally unfortunately) followed by voters. I’ve plotted R, RBI, HR, OBP, SLG and SB as percentiles of the entire population. Let’s take a quick look.

If you like well-rounded players, probably this year you’re excited with Altuve, Trout and Betts, who dominate across the board. In an era where stolen bases keep declining, 20+ SB will get you to the 90th percentile. On the other hand, if you’re into true sluggers, then the show Ortiz has put this season should be one to remember. However, then again, these metrics paint only part of the picture — they don’t take into account when or where each event happened nor they include defense or base running on its most complete form.

Let’s take a deeper look at WAR and a quick indicator for each batting, fielding and base-running performance.

Obviously when we move away from batting, David Ortiz loses ground — he only contributes in one aspect of the game, and while he has been outstanding in the batter’s box, likely it will not be enough for him to win. When we adjust by park and league, we realize the Trout – Betts race for the best OF is not as close as I initially thought. Trout has quietly put a(nother) great season on an awful team (again) — he’s already at 8.1 WAR and a 175 wRC+, with both easily leading the league. His defense is slightly below average at best but he compensates by running extremely well. Altuve and Donaldson have had similar seasons offensively. However, Altuve is having a down season in both defense and base-running (remarkably low on Ultimate Base Running (UBR), which measures how frequently and effectively a runner takes an extra base via running). Betts drives his value largely from his defense, where he’s settled in nicely as one of the best OF this year.

One of the metrics I tend to assess when I look at awards is how performance was spread the entire season. I want an MVP to be someone that I rely throughout the year, not only during a hot stretch. Additionally, having a big month can really uplift the numbers and build up a misleading argument in favor of someone. Let’s understand how wRC+ is split by month.

This picture to me is interesting for a couple of reasons. First, part of the argument on Betts’ candidacy is that he’s getting better, and delivering when it matters the most — in the middle of a pennant race. After a below-average March/April, Betts has been a beast since July, when Ortiz cooled off a bit. Now, then again, Mike Trout has also followed an upward-trending curve — peaking at 206 in August — and his lowest point is at 144, which is the highest of all lowest points in the sample. From my perspective, if everything else is equal, I’d rather have a Trout-esque curve than Donaldson’s one, who has the highest single-month wRC+ (213 in June) but also with the largest swing (118 difference between May and June). And then you have remarkably constant Altuve — with the narrowest gap between highest and lowest points throughout the season and at least 140 wRC+ in any given month.

Now, most of what we have shown up to now is context-neutral. An argument could be made that every single game is worth the same, regardless of whether it’s in April or July — what’s really important is to deliver in key, high-leverage situations. There is where true MVPs show their full potential to influence a team and define its fate. As they say, a home run against a non-contender team when you are losing by five runs is not as valuable as a game-winning double against our wild-card-rival’s closer in the 9th inning. I’ll admit neither OPS in high-leverage situation or Win Probability Added (WPA) is the perfect metric to evaluate this, but they provide a very good proxy to how well they have fared in tough, game-changing situations. If you are not familiar with WPA, please click here.

Again we see the usual suspect — Mike ‘King’ Trout — leading not only this graph but the MLB with his 5.66 WPA, closely followed by Josh Donaldson, and they’re the only two players from this sample to have a higher OPS in high-leverage situations than in low-leverage ones. Interestingly, Boston’s Betts and Ortiz’s OPS go down 9% and 15% respectively when the stakes are high. I definitely don’t want to say that Altuve’s 0.841 OPS in high leverage is bad, but I certainly want to recognize Donaldson’s and Trout’s clutchier performance.

Another way of looking at the MVP is to ask yourself: Where would that team be if that player wouldn’t have been part of it? While in essence it is impossible to know for sure the answer, a nice proxy is to measure what percentage of position-player WAR is that player responsible for, i.e. what percentage share does this player represent.

Well, this is another way to see Mike Trout’s leadership on the field. Almost half of the Angels’ WAR have Trout’s name attached to it, which is amazing. (For reference, the leaders in this table are Khris Davis and Marcus Semien with 122% (2.2 WAR each out of 1.6 Athletics total WAR). Now, Donaldson and Altuve have, too, a remarkable 33% and 35% of their total, but probably Betts falls short again with his 23%.

At the end, when all is said and done, it looks like numbers indicate it should go down to a Donaldson vs. Trout race, just as it was in 2015. Ortiz has had an amazing season but his base-running and defense (or lack thereof) limit his overall impact on his team. Betts is definitely an exciting, five-tool player, but his performance hasn’t been as good as Donaldson’s or as consistent as Trout’s. Additionally, Boston’s talent-loaded team reduces his value (this is the opposite of the Trout-Angels argument – how valuable can you be when your team would perform well, even if you’re not there?). His future is extremely bright though. Finally you have Altuve, who may have a legitimate case but falls (a bit) short on overall performance to Donaldson and Trout. Houston has under-performed and arguably that’s a worse outcome than Trout’s, because we knew the Angels were going to be bad, but we thought the Astros would be better.

Last year, Donaldson built his case with a magnificent August, when he posted a 1.132 OPS and Toronto got to first place in the AL East. This year it was Trout who had a torrid August, but the Angels are not in the wild card race. It surely seems to me as if we are measuring the MVP as a team award. Though I understand the rationale of having an MVP on a winning team, there is more to it. If I had a vote, and still being a few games away from the end of the season, I’d support Trout in his quest for his second MVP (as of today), but it looks like momentum and narrative are gaining traction around Donaldson — who has posted much better numbers than in his MVP season — Altuve — who brings new blood to the MVP discussion and might get an extra push if Houston makes it to the playoffs — and Betts — who is clearly the face of Boston’s extremely talented young generation. They, though, despite great Septembers, will post worse numbers than Trout. Yes, the Angels are a bad team — but to what extend is that Trout’s fault? What else could he have done? When did ‘valuable’ translate into ‘winning by himself beyond reasonable expectations’? When did we change this award to ‘best player on the best team’? In 2012 it was Cabrera’s Triple Crown and in 2015 it was Donaldson’s ‘ability’ to get Toronto to the postseason for the first time in many years. In 2016, Trout has been comprehensively better, avoided any deep slumps during the season, and performed very well under pressure and shown that you can put counting stats up on a bad team. We are running out of excuses this year.
