Brandon Nimmo broke out for the New York Mets in 2018, emerging as one of their core hitters. He featured an excellent combination of power and plate discipline that led him to a .263/.404/.483 slash line and a 149 wRC+, a mark that ranked among the best in all of baseball. In getting to that point, Nimmo developed a more pull-heavy approach at the plate, which led to more hard contact and ultimately more power. Nimmo also featured a high .351 BABIP in 2018, which most would expect to come back down to a more reasonable number because of his tendency to pull ground balls into a shifted infield.

Very few, however, would have expected Nimmo to struggle like he has to start the 2019 season. To this point, Nimmo has put up a .200/.344/.323 slash line, good for a 93 wRC+ in 161 plate appearances, and injury concerns continue to linger. Nimmo’s struggles are playing a big part in the overall difficulties of the Mets lineup, and coaches have offered suggestions to Nimmo that might snap him out of it:

Nimmo disagrees with Callaway, and so do I. Nimmo is one of the more patient hitters in the game, and he likes to wait for a pitch he can do damage with. The problem has been that he isn’t doing damage on those pitches like last year, so I wanted to find out what it is about Nimmo’s profile that could potentially be causing such a slow start.

Are we finally seeing the Lucas Giolito performance that we waited so long for? Once pegged as a “top-of-the-rotation demigod,” Giolito has struggled to find any consistency in the majors. Through the month of May, he’s got the highest K% of his career at 29.2% and the largest K% increase in MLB from 2018 to 2019 with a 13.1% jump. He’s got an average fastball velocity of 93.4 mph, up exactly one tick from last season, and has also added 148 rpm to his heater. Giolito has been more aggressive in terms of overall zone percentage, with the third-largest MLB increase from 2018 to 2019 at 6.8%. Even while down in a hitter’s count, he’s found ways to battle back in the zone, something he was below league average in last season:

Batters are having a tougher time squaring him up and he’s even added some vertical break on his fastball and curveball: Read the rest of this entry »

Aaron Judge and Jose Altuve seem like they shouldn’t coexist in Major League Baseball, but their mutual success reveals an amazing fact about different paths to pitcher dominance.

Here’s a line of reasoning using the transitive property about short hitters and small strike zones:

• If a player is shorter, then his shoulders are closer to his knees.
• If his shoulders are closer to his knees, his strike zone should be smaller.
• If his strike zone is smaller, then it should be harder for the pitcher to throw strikes.
• If it is harder to throw strikes, he should get on base more.
• Shorter players should have higher on-base percentages.

But this isn’t how it actually works. Why not?

Aaron Judge is tall and Jose Altuve is short. That’s analysis. They both are very productive at the plate. That’s deeper analysis. However, Judge gives pitchers a 25% larger strike zone to target due to his 6-foot-7 height, so he must be doing something different and better than Altuve to offset the larger area he gifts to pitchers with every pitch.

It feels somewhat disingenuous to focus a second straight post on a member of the Texas Rangers because I have admittedly not spent much time watching them play baseball in recent years, and by recent years I mean my entire 23-year life. With that said, what little I have watched I can mostly attribute to my enjoyment of two of their current players: Rougned Odor and Mike Minor.

Drafted seventh overall in 2009 by the Atlanta Braves, Minor was a starting pitcher for parts of five seasons with the big league club, four of which were unremarkable but one (2013) which was actually quite good. In that 2013 campaign, he logged 204.2 innings, 181 strikeouts, a 3.21 ERA, and a 3.64 xFIP en route to a solid 3.3 fWAR. Soon afterwards, career-threatening shoulder issues emerged and caused him to miss the entirety of 2015 and most of 2016 before the Kansas City Royals signed him to a minor league deal. In 2017, he pitched 77.2 quality innings out of the bullpen at the major league level, quality enough that the Rangers decided to make him a member of their starting rotation in the following season, which some who were unaware of his pre-Kansas City history probably considered a bit puzzling.

The early returns on what was a somewhat risky and potentially costly investment yielded strong results, especially for a man who had not started a major league game in close to four years. He ranked 37th in fWAR among starters with at least 150 innings pitched, which put him in pretty decent company:

When accounting for the fact that Minor’s career-best 2013 slotted him just four spots higher despite pitching 47.2 more innings, the case can be made that even his micromanaged 2018 workload may have been even more impressive. The risk of the contract has almost evaporated entirely as well. After signing a three-year deal for $28 million, he has already delivered $24 million of value with just a season and change under his belt. A combination of his encouraging 2018 and the Rangers’ relative lack of pitching depth helped the 31-year-old Minor earn the starting nod for 2019’s Opening Day, which, no matter how extreme the dearth of talent may be, is quite meaningful. To be able to say that you had been the ace of a Major League Baseball team when all is said and done (which, barring an injury to a teammate, is usually implied by that honor) puts you in the company of very few people, and it is probably a pretty neat thing to have on a resume.

Over the course of his career, Marcus Semien has been nothing if not consistent. It’s quite remarkable, really — the 28-year-old shortstop has posted between a 95 and 98 wRC+ in each of his three full seasons (and one half season) since being traded to the Oakland Athletics by the Chicago White Sox in 2014. He has long provided a modest blend of power and speed, and his well-documented defensive improvements last year boosted him to a career-high 3.7 WAR and placed him squarely in the tier of not-great-but-pretty-darn-good shortstops in a league flush with some pretty darn good ones.

It may seem a bit strange, then, to suggest that such a player could be on the verge of a breakout, having already “broken out” last year and being on the wrong side of baseball’s aging curve. And yet, in the early weeks of the 2019 season, Semien appears to be suggesting that he is ready to do just that.

A bit of context: Semien has really flashed all the various facets of his potential at one time or another as he’s settled into a regular at shortstop for the A’s, but he hasn’t quite managed to put together a season that has wrapped it all up. He knocked 27 home runs in 2016 (although there was little in his batted ball profile to suggest any sort of adjustment), has consistently stolen around a dozen bags a year, and takes walks at a rate a tick or two above league average (8.2% across his career) — plus the aforementioned improvements on defense.

But, I ask you, what if he made a little more contact? Contact is good for hitters! It’s generally something you strive for. Allow me to present you with an incredibly simple graph:

That is what we in the industry (which one? Not sure) like to call “trending in the right direction.” A career-best 11.2 K% plus a stellar 10.3 BB% have helped Semien hit the ground running in 2019, posting a line of .311/.379/.505 over 116 plate appearances. Am I suggesting that Semien is going to hit .310 for the rest of the year? I am not (yet). Am I suggesting that an early display of improved plate discipline from him could foreshadow a step forward for him this year? We’re getting warmer! Read the rest of this entry »

Before we begin, here is the link to app being discussed: https://cargocultsabermetrics.shinyapps.io/Pitch_Design_Tool/

Two months ago, I wrote a blog post arguing José Berrios should learn a cutter. My argument hinged on the striking similarities between Berrios and Corey Kluber and the fact that Kluber has a good cutter and Berrios does not. Since then, I’ve developed a more objective way to evaluate a pitcher’s current pitches and make recommendations to guide the pitch design process. Pitch design is the process of a pitcher making changes to existing pitches or adding new ones, often using high-speed video and devices such as Rapsodo or TrackMan to get the spin axis of the pitch just right to create desired movement. The app I’ve built creates targets for pitchers and details ideal pitch characteristics to give objective, quantitative direction to the pitch design process.

My plan is to turn the tool into a service for college teams to use for their pitchers in pitch design, but I’ve also created a version which uses Statcast data to create pitch design plans for big leaguers that I’ve released for free. I figured this would be a good place to share the Statcast data version and give a brief explanation of how it works (if you’re interested in a more detailed explanation of the tool, check out this post on my blog).

Trevor Bauer is a walking headline. Whether he is turning himself into some kind of pitching robot in a lab or calling out his peers for using a foreign substance to enhance their spin rate, Bauer tends to attract plenty of attention away from the field. However, Bauer’s most noteworthy accomplishments lately have occurred on the field. Last season, Bauer had more fWAR than Blake Snell, winner of the American League Cy Young Award, despite pitching fewer innings and landing on the injured list for over a month. Bauer, unsatisfied with last year’s performance, developed his previously sparingly used changeup in the offseason to complement his already ample repertoire. Taking a look at Bauer’s pitch usage this year shows a clear difference in the way he attacks righties as opposed to lefties.

Here is his pitch mix vs. righties this season:

And his usage vs. lefties:

Of course, the small sample size caveat applies at this point of the season, but Bauer has been featuring a changeup against lefties at a much higher rate than last season.

Here’s Bauer’s 2018 pitch usage against lefties:

Bauer now throws his changeup twice as often as last season against lefties, and so far the results have been good. The pitch has produced a 75% ground-ball rate when put in play, and opposing batters have only recorded a single hit off of it.

While Bauer has certainly adjusted his method of attacking lefties, an early breakdown of how he has attacked righties is even more intriguing. Here’s his 2018 pitch usage vs. right-handed batters:

Comparing Bauer’s 2018 and 2019 pitch breakdown against righties reveals a few monumental adjustments. Bauer has evidently abandoned his signature knuckle curve and replaced it with a sharp increase in the usage of a cutter. In my opinion, these adjustments were made in the name of tunneling. Sliders and cutters both have primarily sideways movement, which makes it more difficult for the batter to differentiate between them. Curveballs and changeups both tend to break downwards, causing the same confusion for batters. By pairing these pitches against righties and lefties respectively, Bauer decreases the chance that a batter can read the pitch correctly out of his hand.

Up until this point, Bauer has been sharp, using his new changeup and dedication to tunneling to strike out a third of the batters he has faced and firing seven no-hit innings on April 4th against the Blue Jays. Through five starts, Bauer has struck out 32.6% of batters and at least seven in each outing. As Bauer continues to tweak his approach, perhaps he could benefit even further by lowering his fastball usage, mimicking the strategy of many pitchers before him, in order to combat hitters who sit on the pitch ready to unleash uppercut swings. By lowering his fastball usage and further utilizing his tunneling ability, Bauer will be even more unpredictable to hitters.

Time will tell if Bauer’s new strategy will be successful all year, but based on his dedication to both analytics and his craft, he seems to be on pace for another Cy Young caliber season.

As the 2019 season begins, Las Vegas determines the annual over/under win totals for all 30 major league teams and gives us a chance to examine intriguing over/under win lines for the upcoming season. Not surprisingly, the Miami Marlins found a spot right at the bottom of the list at over/under 63.5 wins. Will the Miami Marlins, under the ownership of Derek Jeter and the tutelage of Michael Hill, elude the worst record in baseball? Call me crazy, but there are a number of reasons why Vegas’ determination of 63.5 wins is undervaluing the Marlins.

J.T. Realmuto, a 2018 All-Star and arguably the last star on the Marlins roster, was acquired by the Philadelphia Phillies for Jorge Alfaro, Sixto Sanchez, and Will Stewart this past offseason. While Sanchez is a potential budding ace pitcher and Stewart has a real future as a middle-of-the-rotation starter, Alfaro is the most interesting addition for the 2019 season. He rates as a guy with incredible raw power when he puts the bat on the ball, with the only issue thus far in his career being that his contact percentage is quite low:

The K% is good for 245th out of 247 players (min. 350 PAs) and the BB% ranks in the 8th percentile among those same 247. By looking at his O-Swing%, it’s good for second-to-last and 16% above the 2018 league average of 30.9%, and clearly he’s not making enough contact at 61%. However, when Alfaro does manage to put bat on ball, the results are quite impressive:

How about a video of the swing in action? This ball, at 115 mph off the bat of Alfaro, was absolutely crushed, and I think Junichi Tazawa’s reaction says it all…

With more patience and a better approach at the plate, the Marlins could have something special in Alfaro. It’s evident that this improved approach could be on it’s way by analyzing his second-half statistics from July 2018 to September 2018:

Alfaro managed to cut his K% and increase his BB%, while performing as an above-average hitter according to wRC+. He made strides at the plate by lowering his whiff percentage outside of the zone from 28% in the first half to 25% in the second half, and his batted ball quality improved against breaking pitches, which he had struggled with mightily in the first half, as his xwOBA increased from 0.246 to 0.338 in the second half and his whiff percentage on breaking balls decreased from 34.68% in the first half to 26.52% in the second half.

As far as breakout years are concerned, Rougned Odor did a bang-up job in 2016. His 33 home runs as a 22-year-old regular gave his baseball card a hefty amount of pop, but not as much as he gave Jose Bautista during their infamous run-in at second base.

I am not generally a fan of fisticuffs on the field, but this incident was and remains a touchstone for the 2016 season. However, in becoming so it may have, to the casual fan at least, reduced what was a solid season for one of the league’s youngest players to no more than a single moment. But Odor has, in fact, done more baseball things since that fateful afternoon, and the past couple of seasons paint a fascinating picture of a player who may not have improved overall, but one who has changed a whole lot and could very well have his best years ahead of him.
Over the past five years, he’s become a fixture at second base for the Texas Rangers, never appearing in less than 114 games during that span and accumulating a total of 7.2 fWAR. Save for his abominable 2017 campaign, which resulted in -1.2 fWAR, his career, despite no shortage of deep slumps and hot streaks, has been shockingly consistent: he’s totaled exactly 2.5 fWAR in three of the past four seasons. His career has played out much more interestingly than those identical numbers suggest, however, namely in that each campaign has played out quite differently (part of the fun of WAR!). The most pronounced changes, however, have occurred since that breakout 2016.

Though he posted identical fWAR totals in 2015 and 2016, the latter year was his first with at least 600 plate appearances, which helped him make quick work of his career-highs in the fan-favorite counting stats, namely home runs (33), RBIs (88), and stolen bases (14). A healthy-yet-not-unsustainable .297 batting average on balls in play (BABIP) anchored a solid .271 batting average, and 70 extra-base hits made for an impressive .502 slugging percentage. A paltry 3% walk rate kept his on-base percentage below .300 (.296), which limited his overall offensive production and kept his wRC+ at 103 (the league average is set at 100.) The 6.1 offensive runs above average remain a career high, but despite being 2.5 runs better than average on defense in the year prior, his -3.5 mark in 2016 remain a career low.

Yoan Moncada has frustrated talent evaluators over the past two years. He’s about as physically talented as a baseball player can be; while still a prospect, the team here at FanGraphs thought he merited future grades of 60 hit, 60 power, 70 speed, 50 field, and 70 throw, with an OFP of 70 good for No. 1 overall prospect status. Prospects don’t get evaluated much better than that; in fact, a 70 OVR on a position player is as good as it gets. He was the kind of prospect that could headline a trade for a top-five starting pitcher, a bonafide ace, in his prime on a team-friendly contract with three years left.

Flash forward two years, about a year and a half into Moncada’s major league career, and he hasn’t performed quite as billed. Instead, in 901 career plate appearances before Opening Day 2019, he posted a 97 career wRC+ and 3.1 total fWAR, almost exactly league-average or slightly below. His defense at second base has not impressed, and so he’s being moved to the hot corner in the wake of 1) the White Sox whiffing on Manny Machado, and 2) the White Sox drafting “future Gold Glove second sacker” Nick Madrigal with the 4th overall pick in 2018. If nothing changes, he’s be in danger of becoming a utilityman.

Moncada’s offensive struggles are a little unusual. He has two traits required to be an offensive monster — power and patience — in abundance. Last year, his average exit velo of 90.6 mph was in the 86th percentile, while his 4.12 pitches seen per PA was in the 81st percentile. However, those positive traits were offset by the modern game’s bugaboo — strikeouts. Moncada struck out in an ugly 33.4% of his PAs last year, behind only Chris Davis and Joey Gallo, and his career K rate sat at 33.6% this offseason. This is very concerning, as contact issues are a flaw that are difficult to resolve.

The profile above seems to describe a three-true-outcomes hitter like the aforementioned Gallo. Dig a little deeper, though, and you’ll find that how Moncada struck out that often is not normal, and in a sense he doesn’t actually have contact issues, at least not 33.4% bad. He didn’t chase many pitches out of the zone last year — only 23.3% — sitting in the 87th percentile of qualified hitters. Neither does his whiff rate of 12.2% (league average in 2018 was 10.7%) jibe with that huge strikeout rate. Taken together, we can conclude that while Moncada’s contact ability may be somewhat below-average, he limits how much he swings-and-misses by rarely chasing pitches out of the zone. So if Moncada doesn’t chase much, and doesn’t swing and miss that much, how is he striking out so much? Read the rest of this entry »
