Locke St. John and the Lateral Movers

Benny Sieu-USA TODAY Sports

Last week, I wrote about the handful of pitchers who drop their release points significantly when facing same-sided batters. Today I’m going to highlight a few who change their release points by a different method. Before we get to them, I’d like to talk a bit about why anybody would risk messing with their release point in the first place. This is an article about the potentially transformative power of scooching over.

I started thinking about arm angles with a very blunt test. For the last seven years, I pulled every pitcher’s average release point and their wOBA against lefties and righties, then calculated the correlation between them. I also pulled average velocity as a control variable of sorts. The correlation coefficients are small, but they line up with what we’d expect:

Correlation Between Release Point and wOBA
Handedness Velocity Horizontal Release Point Vertical Release Point
Same Side -.15 -.11 .15
Opposite Side -.22 .13 -.01
Minimum 800 pitches against relevant side.

Unsurprisingly, it’s always good to throw the ball hard. Against same-sided batters, pitchers who release the ball lower and wider fare better. Against opposite batters, a wide release point is associated with poor results. Read the rest of this entry »


Ralph Garza Jr. and the Sometimes Sidearmers

Akash Pamarthy / USA TODAY NETWORK

Back in November, left-hander Tyler Anderson signed with the Angels, and Ben Clemens wrote a super interesting piece about the deal. How did Ben make his article so interesting? By cheating. He was already writing a cool article about Anderson, so rather than start from scratch, he just folded the existing article into one about the signing. It was unfair to the rest of us who struggle to keep up with Ben even when he’s not juicing.

What Ben noted is that in 2020, Anderson started throwing his sinker from a lower arm slot against lefties. More recently, he started doing the same with some of his cutters. Dropping down some for his cutters meant that hitters could no longer assume that a low release point meant a sinker was coming, and it also improved the cutter’s performance. In 2022, lefties had a wOBA of .268 and an exit velocity of 79.5 mph against Anderson’s regular cutter. The drop-down cutter was at .124 and 76.3.

Inspired by Anderson’s novel approach, I went looking for pitchers who do the same thing. We’re not just looking for players who drop down some to throw certain pitches; there are too many of those to list. We’re specifically looking for players who dramatically change their arm angle depending on the handedness of the batters they’re facing. Once you weed out position players, who understandably have very inconsistent release points, there are only a few players who fit those parameters. Just six pitchers had a difference of more than three inches between their vertical release points against righties and lefties:

Vertical Release Splits (Feet) – 2022
Player vs. LHB vs. RHB Difference
Ralph Garza Jr. 5.59 4.02 1.57
Rich Hill 4.82 5.71 .89
Humberto Castellanos 5.37 4.97 .40
Yennier Cano 5.65 5.28 .37
Tyler Anderson 5.73 6.07 .34
Joe Smith 3.30 3.00 .30

As It Was Foretold, Nathaniel Lowe Has Broken Out

Kiyoshi Mio-USA TODAY Sports

Just under a year ago, Jake Mailhot identified Texas first baseman Nathaniel Lowe as a player with breakout potential. In fact, he wrote a whole article called, “Nathaniel Lowe Has Breakout Potential.” Then the 2022 season happened, and — you guessed it — Nathaniel Lowe officially broke out. He hit 27 home runs and raised his wRC+ from 114 to 143. Good for Nathaniel Lowe! He’s a slugger. Good for Jake Mailhot! He’s a clairvoyant.

The thing is, Lowe didn’t exactly follow the script laid out for him. Jake noted that for the last month and a half of the 2021 season, Lowe added some “responsible aggression,” lowering his strikeout rate despite swinging more often. He did that by making a ton of contact in the zone. Jake broke Lowe’s 2021 plate discipline stats down in a table, using August 16 as the dividing line. I’ve gone ahead and added 2022 to that table:

Nathaniel Lowe, Plate Discipline (Reprise)
Date PA BB% K% O-Swing Z-Swing Z-Contact
Pre-8/16/21 471 12.7% 27.0% 22.8% 62.6% 83.5%
Post-8/16/21 171 11.7% 20.5% 24.0% 64.9% 90.4%
2022 645 7.4% 22.8% 34.9% 75.0% 86.7%

Dominic Smith Secures a Position With the Nationals

Brad Penner-USA TODAY Sports

The Nationals have found the left-handed bat that they were looking for. Yesterday, Bob Nightengale reported that Dominic Smith has signed a one-year deal that will send him down I-95 to Washington. Robert Murray of FanSided reported that the deal was for $2 million, with performance bonuses worth up to another $2 million. According to Joel Sherman of the New York Post, those bonuses relate to the number of plate appearances Smith makes. The Nationals 40-man roster is full, so they will need to make a move in order to clear space for Smith.

After snagging Jeimer Candelario on a one-year deal in November, the Nationals have now filled both corner infield spots with free agent bounce-back candidates. In Washington, Smith might finally get the one thing he’s always needed: time. After six big league seasons, the 27-year-old Smith has never had a regular position, and has topped 200 plate appearances just once.

Nightengale also reported what might be the most important part of this story: that Smith will be playing first base for the Nationals. Although the team non-tendered Luke Voit earlier in the offseason, that was not necessarily seen as a certainty. Manager Dave Martinez said during the Winter Meetings that he hoped first base would be the primary position of 2022 rookie sensation Joey Meneses. Over the course of his career, Smith has spent more innings in the outfield than he has at first. It’s at least reasonable to imagine that playing every day at his preferred position could make a real difference to a player who’s never had the luxury of stability. Read the rest of this entry »


Amed Rosario Can’t Stop Running

Amed Rosario
Kevin Jairaj-USA TODAY Sports

I don’t know if you’ve heard, but here at FanGraphs we enjoy the occasional number. Even our logo has its own bar graph. Today our topic is competitive runs, a statistic that rarely gets the love and appreciation it deserves, due to the fact that it’s mostly made up. Competitive runs is a classification created for Statcast. In order to measure average sprint speed, you need a pool of plays when players will presumably be running their hardest:

Competitive runs are essentially just the sample size. When you go to Baseball Savant’s leaderboard, the players are always sorted from fastest to slowest. However, you can also sort by competitive runs, and I can never resist. All season long, one player was absolutely trouncing the field:

2022 Competitive Runs Leaders
Player Competitive Runs Sprint Speed
Amed Rosario 342 29.5
Brandon Nimmo 282 28.7
Vladimir Guerrero Jr. 279 26.6
Trea Turner 276 30.3
Steven Kwan 272 28.4
SOURCE: Baseball Savant

Amed Rosario is the grand champion of competitive runs. The difference between Rosario in first place and Brandon Nimmo in second place is the same as the difference between Nimmo and Jeff McNeil in 34th place. I’m sure Nimmo takes some solace in knowing that he’s the undisputed leader of the non-competitive run. Whether it’s a walk or a hit by pitch, the dude straight up loves scampering to first base for his own particular reasons:

Turning our attention back to Rosario: It’s not as if he’s just racking up competitive runs as a counting stat. He also leads the league on a rate basis, no matter which rate you choose:

2022 Competitive Runs Leaders
Rank Player Per Plate Appearance Rank Player Per Ball in Play
1 Amed Rosario 51.0% 1 Amed Rosario 64.5%
2 Isiah Kiner-Falefa 48.2% 2 Isiah Kiner-Falefa 60.9%
3 Starling Marte 44.2% 3 Starling Marte 60.4%
4 Luis Rengifo 43.4% 4 Brandon Nimmo 60.0%
5 Steven Kwan 42.8% 5 Juan Soto 59.6%

I don’t know about you, but I think this is incredibly fun. Competitive runs is an incidental statistic. It’s just scaffolding for another stat, but there’s one person who plays baseball like competitive runs is his own personal pinball machine. The other reason I love it is that even though competitive runs exists only to serve a higher master, it’s still a descriptive stat in its own right. A player’s competitive runs total tells you plenty about the way they play the game. Read the rest of this entry »


Orioles Continue Playing Small Ball, Sign Mychal Givens

Mychal Givens
Vincent Carchietta-USA TODAY Sports

Right-handed reliever Mychal Givens is returning to the Orioles. The deal is for one year and $3 million, with a mutual option for 2024 worth $6 million. If he declines the 2024 option, he receives a $1 million buyout. If he accepts and the Orioles decline their end, he receives a $2 million buyout. Baltimore’s 40-man roster is full, so the team will need to make a move to clear space for him.

Coming off a 2022 season in which he posted a 3.38 ERA and a 3.96 FIP over 61.1 innings, Givens provides some experience to a young Baltimore bullpen that features standouts like Dillon Tate, Cionel Pérez, and closer Félix Bautista. Baltimore’s relief corps was ninth in the league with a 3.49 ERA in 2022, with a 3.72 FIP and 3.53 SIERA that ranked seventh and 13th, respectively.

The Orioles selected Givens out of high school in the second round of the 2009 draft. Originally a shortstop, he missed a couple of seasons after injuring his thumb sliding into first, strengthening the arguments of baseball curmudgeons the world over. He converted to pitching in 2013, reached the majors two years later, and made an immediate impact, posting a 1.80 ERA and 0.9 WAR in just 22 appearances. Over his first four big league seasons, his 5.1 WAR was 15th among all relievers. Read the rest of this entry »


Steven Kwan, Geraldo Perdomo, and the Victor Robles Problem

© Sam Navarro-USA TODAY Sports

Sorry, but this is going to be kind of a bummer. Our topic today is the crushing weight of statistical determinism. In researching this article, I learned something that increased my knowledge but also decreased my sense of the possible, and it made me a little bit sad. I would now like to share my sadness with you. We’re going to be studying the Victor Robles Problem.

You might not remember the days when Victor Robles was a star prospect. After short, impressive stints in 2017 and ’18, he had a breakout season in 2019, putting up a 92 wRC+ and 3.5 WAR, and finishing sixth in NL Rookie of the Year voting. ZiPS projected him for 3.3 WAR in 2020. If he could take the next step offensively, he’d be a star; if his offense remained just a bit below average, he’d still be a very productive center fielder. Instead, he turned in three straight seasons with a wRC+ under 70. Here are the Statcast gearboxes for his rookie season and 2022:

There’s a whole lot of blue in the top two rows. Plate discipline was the concern when Robles was first called up, and that was certainly an issue, but the lack of power stands out much more. Although his max exit velocity indicates that he has the capacity to hit the ball hard, Robles’ average exit velocity has been in the first percentile in each of his big league seasons, and his hard-hit rate has never been better than fifth percentile. The Victor Robles Problem is a question: Can a player who didn’t hit the ball hard as a rookie ever turn into a good hitter? Read the rest of this entry »


Nationals Find Their Veteran Starter in Trevor Williams

Trevor Williams
Vincent Carchietta-USA TODAY Sports

A week ago at the Winter Meetings, Nationals manager Dave Martinez told reporters that the team was looking to add a veteran starting pitcher. On Friday, MASN’s Mark Zuckerman reported that Washington did just that, making its biggest move of the offseason by signing free agent Trevor Williams. The two-year, $13 million commitment, per The Athletic’s Stephen J. Nesbitt, represents the team’s third-biggest contractual commitment, behind the long-term deals of Stephen Strasburg and Patrick Corbin.

Williams played a significant role with the Mets in 2022, starting nine games while Jacob deGrom and Max Scherzer were on the IL earlier in the season and making 21 relief appearances. Given New York’s glut of solid right-handed relief arms, he didn’t make the roster for the Wild Card Series against the Padres. Had he been on the Nationals in 2022, his 0.6 WAR would have been third on the staff, and his 3.21 ERA and 3.88 FIP would have been fourth (among pitchers who threw at least 25 innings).

Williams will immediately become the most reliable arm in Washington’s starting rotation. At Federal Baseball, Patrick Reddington noted that he had a 1.80 ERA against the Nationals in 2022, so if nothing else, they’ve co-opted a former tormenter. Read the rest of this entry »


Mets Bolster Starting Rotation With Two-Year Deal for José Quintana

Jeff Curry-USA TODAY Sports

The Mets have done it. They’ve finally landed a superstar starter to replace Jacob deGrom. Wait, sorry, I’m being told that someone already wrote about the Justin Verlander signing. Instead, I’m here to talk about José Quintana, who signed a two-year, $26 million contract, according to The Athletic’s Ken Rosenthal and Will Sammon.

Just to be clear, Quintana was a very good pitcher in his own right this year. Despite his 6–7 record (I’d like to see you try starting a game for Pirates and being credited as the winning pitcher), he posted 4.0 WAR, a 2.99 FIP, and a career-best 2.93 ERA, pacing the Cardinals down the stretch after a deadline trade.

The 34-year-old will no doubt enjoy his new role as the precocious youngster of the Mets’ starting staff, next to wizened aces Verlander and Max Scherzer. In fact, as the rotation stands now, the 27-year-old David Peterson is the only starter younger than Quintana. The Mets will be expecting a whole lot of innings from pitchers who are just a few years away from having an entire bookshelf devoted to biographies of Winston Churchill.

The 2022 Reds Broke Records and Battered Batters

Nick Lodolo
Michael McLoone-USA TODAY Sports

You might have heard that the Mets got hit by a record 112 pitches in 2022, but New York wasn’t the only record breaker in that particular category. Cincinnati’s pitching staff breezed by the 2021 Cubs’ modern era record of 98 HBPs with weeks left in the season, and they kept right on plunking. In the last game of the year, Graham Ashcraft sailed a sinker into both the triceps of Patrick Wisdom and the record books, giving the Reds 110 hit batters for the season. That number edged them past the 1899 Cleveland Spiders as the most contact-oriented team of all-time.

Those bloodthirsty Spiders hit 109 batters and lost 134 games, then folded just before the invention of the zeppelin. Eleven of those HBPs and losses were credited to Harry Colliflower, a former carpenter who won his first start, then lost 11 straight decisions and his spot in the big leagues. That’s the company the 2022 Reds kept. Read the rest of this entry »
