Evaluating Trevor Bauer’s Pitch Usage

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.

Why There May Just Be Hope for the Miami Marlins in 2019

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.

Rougned Odor Has Changed, but Can He Improve?

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.

Is Yoan Moncada’s Breakout Coming?

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 »


Getting Joe Musgrove to the Next Level

Joe Musgrove was a pretty ordinary pitcher in 2018, with a 103 ERA- and an 89 FIP- according to FanGraphs. He once again battled through injuries on the way to a career-high 115.1 innings, and he had more woes to deal with in the offseason by undergoing abdomen surgery. He doesn’t particularly stand out in Pittsburgh’s rotation, as he doesn’t have the track record or high transaction cost of Chris Archer, he doesn’t have the easy-to-root-for, feel-good story of cancer survivor Jameson Taillon, and he doesn’t have the intriguing out-of-nowhere 2018 performance of Trevor Williams. He is rather ordinary among starting pitchers. Even when I ran a query of starters with similar 2018 statistics, I got back a list of some good-but-perhaps-underwhelming hurlers. Look here:

musgrove comps 1

Nothing against these pitchers (especially Miles Mikolas, who had a good but perhaps unsustainable 2018 when looking at xFIP and SIERA, which he at least parlayed into a big contract extension), but these aren’t names that come to mind first when you think of the top pitchers in the league, and Garrett Richards isn’t usually on the mound to move up into that category in the first place.

This isn’t a great endorsement for Musgrove, so why am I interested in him? I drafted Musgrove in both of my fantasy baseball drafts earlier this month, prioritizing him over the other names in the above table. I did this based on the work of Nick Pollack, founder of the great website Pitcher List and contributor to FanGraphs, who has talked up Musgrove for awhile now. On the now- famous Top 100 Starting Pitcher Rankings featured on Pitcher List, Musgrove ranks 44th, ahead of the previously mentioned Archer (54), Alex Wood (69), Marco Gonzales (77), and other notable pitchers such as Cole Hamels (47), Jon Lester (48), and Dallas Keuchel (73). There must be an explanation for this. Read the rest of this entry »


The New-Look Phillies Lineup Plans on Stealing All Your Strikes

You’ve probably heard of how pitchers and catchers can steal strikes via expert control and framing. Some guys are just so good at painting the edges that they get those calls, plus the benefit of the doubt on the ones that push a little further outside. Think Zack Greinke, Aaron Nola, or Kyle Hendricks for pitchers. On the catching side, the names are less heralded, but think Yasmani Grandal, Jeff Mathis, or Max Stassi. They all deliver or receive the ball with such veracity that it’s almost magical to witness as a viewer, and probably infuriating as a hitter.

But all’s fair in love and baseball. If pitchers and catchers can aid themselves in stealing strikes that help them get outs, logic follows that hitters can do the same to prolong at-bats, even if we don’t necessarily talk about it under the same terms. Certain guys are just better than their peers at knowing when to swing and when not to, whether the ball is in the zone or not. And maybe, just maybe, that’s part of why the Phillies went out and acquired Andrew McCutchen and Bryce Harper this winter: they know when they can afford to not swing, even if the ball ends up on the edges or in the zone. In addition to Rhys Hoskins and Cesar Hernandez, the team now has three of last year’s top five hitters in baseball (and four of the top 30) at getting pitches in those spots to be called balls.

phils strike stealers

There’s a lot to unpack here. In each of the past three seasons, only about 220 hitters have qualified to be a strike thief each year by having seen at least 1,500 pitches. While hypothetically that works out on average to about seven guys per team, it’s certainly not how the talent is actually distributed. Just seven teams accounted for half of the top 30 alone in 2018. In many respects, what one team has is what another inherently can’t. Read the rest of this entry »


2019 Free Agents Got 91.5% of What We Expected

(…or “Fun With FanGraphs’ Free Agent Tracker and Excel”)

The 2019 offseason was an interesting and surprising one. It continued the recent trends of free agents signing later and of several prominent free agents getting less than expected. There was debate here at FanGraphs and elsewhere on whether free agency is broken, no longer working as intended, and if it could lead to a labor shutdown. Others see the big money earned by Harper and Machado as evidence that all is fine. I wanted to take a closer look, informed by data and some quick-and-dirty analysis.

On March 3, 2019, I went to FanGraphs’ free-agent tracker and selected the first 60 free agents listed in descending order of total value of newly signed FA contract. I removed the 13 players who were not featured in reader contract crowdsourcing, leaving 47 players, ranging from Bryce Harper ($330M) to Lonnie Chisenhall ($2.8M). I then compared the total years and total dollar values from crowdsourcing to the actual signed contracts. Here’s what I found. Read the rest of this entry »


Mike Trout and The 1% Club

Like many other followers of FanGraphs, I never seem to get enough articles about Mike Trout — the general theme being: “another way Mike Trout is so great” — so I want to share one of my own. Contrary to popular belief, Trout did not invent WAR; even more shocking, the metric wasn’t developed for the primary purpose of showcasing how valuable he is. But that of course is what it does do. Many readers may know that beginning with his first full season, at age 20, and continuing up to his most recent, age 26, Kid Fish has had the most WAR through every season but one — his age-25 season, when he missed nearly fifty games with an injury — than any other player in history. So it shouldn’t be surprising that he is one of just 20 members of what I call The 1% Club: players who have equaled or exceeded 0.010 WAR per PA for their entire careers.

In fact, he’s currently second only to Babe Ruth:

Career War/PA Of 0.010 Or Greater
Player fWAR/PA (career) fWAR/PA (age 26)
Babe Ruth 0.0159 0.0172
Mike Trout 0.0138 0.0138
Rogers Hornsby 0.0138 0.0134
Ted Williams 0.0133 0.0139
Barry Bonds 0.0130 0.0107
Lou Gehrig 0.0120 0.0121
Willie Mays 0.0120 0.0120
Honus Wagner 0.0118 0.0080
Ty Cobb 0.0114 0.0131
Mickey Mantle 0.0113 0.0129
Tris Speaker 0.0109 0.0123
Joe DiMaggio 0.0108 0.0123
Joe Jackson 0.0106 0.0109
Mike Schmidt 0.0106 0.0109
Jackie Robinson 0.0106* —
Jimmy Foxx 0.0105 0.0122
Dan Brouthers 0.0104 0.0118
Nap LaJoie 0.0103* 0.0095
Eddie Collins 0.0100 0.0125
Stan Musial 0.0100 0.0116
*rWAR

This list is based mostly on FanGraphs’s fWAR, and is for players with a minimum of 50 career WAR. However, two players, Nap LaJoie and Jackie Robinson, don’t quite qualify by fWAR, but they do if we use Baseball Reference’s rWAR (all the others on the list qualify using either metric). Trout is the only active player on the list, though if we lower the bar to 30 career fWAR, three more players appear, including Mookie Betts, who is at 0.0104. Even lowering the criterion to just 10 fWAR adds just one more active player, Aaron Judge (0.0103). Read the rest of this entry »


How Blake Treinen Dropped 3.15 from His ERA

Blake Treinen had an outstanding year. You know that, I know that, he knows that, and his 9-2 record, 0.78 ERA, 38 saves, and 100 strikeouts says that. But how exactly did a run-of-the-mill reliever drop more than three runs from his ERA to have one of the best reliever seasons in history? I don’t know about you, but I think that’s what this article is all about.

Let’s start with some comparable seasons. First up, we go to Hall of Famer Dennis Eckersley. He only had one season in his 24-year career that compares to the brilliance of this Treinen’s 2018 campaign. That was 1990, when Eckersley was 35 years old and compiled a 0.61 ERA in 73.1 innings pitched with, coincidentally, 73 strikeouts, as well as 48 saves in 50 opportunities.

Secondly, Zack Britton’s 2016. I’m sure you remember Britton’s amazing season: 0.54 ERA, 47 saves, 67 IP, 74 strikeouts, and zero blown saves. That season was exceptional, and I must say, better than Treinen’s.

Finally, Jonathan Papelbon’s 2006: 0.92 ERA, 35 saves, 86.1 IP, and 75 strikeouts.

And that’s it. After searching both Baseball-Reference and FanGraphs, these three seasons are the ones I can find similar to Treinen’s. None of Mariano Rivera, Lee Smith, Trevor Hoffman, or Aroldis Chapman had a season like this.

Enough with those numbers, let’s move on to other numbers. Read the rest of this entry »


A Closer Look at Luke Voit

When PECOTA projections were released at Baseball Prospectus in February, I’m sure that I wasn’t the only one who was surprised to see Luke Voit projected to be a top-25 hitter in the entire sport this season. We all know what Voit did in the final month or so of the 2018 campaign, and when you look back on it, there were always going to be questions of whether it was repeatable or whether he was going to go down the same path as famed Yankee flash-in-the-pan Shane Spencer.

I think there can be a comfortable medium between one-hit wonder and top-25 hitter in baseball, so I decided to do a deep dive into Voit’s batted ball profile. I then compared him to his peers based on both his profile as well as his walk and strikeout rates to find some comparable hitters and try to answer whether a top-25 projection for Voit is realistic, too high, or too low.

To do this, I took the batted ball leaderboards from FanGraphs and imported them into R. I then looked at Voit’s batted ball profile from the minor leagues, considered by Yankees officials to be part of the reason why they wanted to acquire him. I calculated his minor league averages in Ground Ball%, Line Drive%, Fly Ball%, Pull%, Center%, and Opposite%, which can be found in the table below:

voit_minors

Note: I only looked at minor league seasons in which he had more than 100 plate appearances. Read the rest of this entry »
