Matt Wisler has thrown his slider 89.2% of the time this year, the highest percentage of any pitcher in either league. He’s done so over 32-and-two-thirds innings, the last 12-and-a-third of them with the Tampa Bay Rays, who acquired the 28-year-old right-hander from the San Francisco Giants on June 11 in exchange for minor league southpaw Michael Plassmeyer. Since coming to his new club, Wisler has made a dozen appearances and allowed just one earned run.

Wisler told the story behind his signature pitch over the phone earlier this month.

———

Matt Wisler: “I’d say I learned [a slider] in high school. I’d always thrown a curveball growing up — from when I was 11 or 12 — and then around sophomore year I started throwing a slider. It was honestly more like a different variation of a curveball, though. It was just a little bit different spin.

“The slider I have now, I learned in Low-A way. My pitching coach was Willie Blair, and we were trying to get more separation between my curveball and my slider. We went through a bunch of different grips. Finally, the second time I tried his grip, it kind of clicked for me. That was in 2012. I’ve kept that one ever since, and have obviously started throwing it more and more over the last couple of years.

“My original slider was more like a slurve — it was probably high-70s, low-80s — and we were trying to find a pitch that I could get into the low- to mid-80s with a little bit different break. There are still times where it will get a little slurvy and be in the high-70s, and a little bigger and rounder. Read the rest of this entry »

Baseball just wrapped up All-Star week, or better put, baseball just wrapped up Shohei Ohtani week. What more can be said? He hit six 500-foot home runs in the Home Run Derby on Monday night, then served as both the American League’s starting pitcher and leadoff hitter in the All-Star Game on Tuesday. On the mound, he threw an even 100 mph and earned the win after his one spotless inning of work.

All that put Ohtani front and center, as it should have. He is baseball’s home run leader, with 33. He’s slugged nearly .700, and among qualified hitters, his 180 wRC+ is beat only by Vladimir Guerrero Jr.’s 189. He has also made 13 starts on the mound, pitching to a 3.49 ERA; his 30.7% strikeout rate ranks seventh in the AL among those with at least 50 innings. We are so lucky to have borne witness to a first half that has been uniquely and historically great.

Part of the reason Ohtani has been such a marvel this season is his sheer volume of play. When he first entered the majors in 2018, the Angels sat him on the days both before and after his pitching appearances. This season, though, things are different, as he appeared in 87 of the team’s 89 first-half games. What’s more, he has also taken at-bats in 10 of his 13 starts on the mound. The Angels said during spring training that they wanted to maximize Ohtani’s usage this season, and they certainly have. That’s just one of the many ways in which he has impressed; he’s a two-way player who’s playing just about every single day. Read the rest of this entry »

As we’ve passed both the literal midpoint of the season (1,215 games) and the philosophical one (the All-Star Game), it’s time to look back at the sample-size-fueled joy and sadness of the best and worst individual player projections for the first half. Projecting this season was particularly tricky for the obvious reason that the 2020 season was only 60 games and there was no minor league season at all. There’s not really much you can do to compensate for the lack of data; in the end, you’re likely to be less accurate no matter your approach. This isn’t as big a deal when it comes to the team projections, where there are enough players that you just hope the mistakes aren’t all in the same direction, but it can matter when you’re talking about a single player. (In hindsight, it makes me happy I never needed to project the 1995 season using replacement players, if that had actually happened.)

Let’s start with the hitters. Given the volatility of defensive measures, this is a comparison of the offensive numbers, not WAR as a whole. I’m setting 200 plate appearances as the minimum. Here are the position players ZiPS most underrated:

A story recently emerged that captured the hearts of even the stoniest baseball fans. On June 19, a little girl named Abigail attended her first major league game in Cincinnati and was over the moon to get to see her hero, Joey Votto, in action. But as fate would have it, Votto was ejected in the first inning, leaving young Abigail devastated; a photo of her forlorn face, eyes brimming with tears, made the rounds on Twitter. Soon enough, though, she had a signed ball in her hands, and later that same week, she returned to the park and got to meet Votto in person. A photo of her beaming expression might best summarize the whole experience:

Today was AMAZING!!! ???? Thank you, from the bottom of our hearts, to Joey Votto & the @Reds for the wonderful tickets to today’s game & for taking the time to meet with Abigail. She is absolutely thrilled & couldn’t have had a better weekend! Thank you for making it so special! pic.twitter.com/n0JL8YAUIJ

The entire story, from Abigail’s excitement to the perfectly-timed misfortune of Votto’s ejection to the entirety of baseball Twitter rallying around this one little girl, felt like the plot of a movie, with our hero, in this case, a fan ready to cheer for her favorite player.

Abigail’s story is not a movie, of course. It will become a fun memory to look back on later in her life and probably helped solidify her as a Reds fan. Not every fan can have the kind of direct experience she did; not every child can meet their hero. But what makes Abigail’s story special is that it’s centered on her and not Votto. He was a just a peripheral part of what made this tale unique, and that is what made it so touching and engaging for others to follow.

Joey Gallo didn’t win in his long-anticipated Home Run Derby debut — he didn’t even make it out of the first round or hit a single 500-foot drive at Coors Field on Monday night — but he earned his trip to Denver’s All-Star festivities nonetheless. After an injury-marred 2019 and a dismal follow-up in the pandemic-shortened season, the 27-year-old slugger is putting together his best and most complete campaign.

Gallo’s second All-Star appearance was less eventful than his first. He replaced starter Aaron Judge in the bottom of the fifth inning of Tuesday night’s game, but didn’t get to bat until the eighth, when he drew a walk against Mark Melancon in his only plate appearance. In his All-Star debut two years ago, he had entered in the sixth inning, and swatted a solo homer off Will Smith in his lone plate appearance in the seventh. That run, which at the time extended the American League’s lead to 4-1, proved to be the difference-maker in the Junior Circuit’s 4-3 win.

In between those two appearances, Gallo’s had more downs than ups, but he’s worked hard to earn his way back. Having slugged 81 homers while batting a lopsided but respectable .208/.322/.516 (113 wRC+) in 2017-18, he was in the midst of a breakout campaign when the ’19 All-Star game rolled around, hitting an eye-opening .275/.417/.643 (162 wRC+) with 20 home runs in 61 first-half games. An oblique strain that sidelined him for over three weeks in June left him 19 plate appearances shy of qualifying for the batting title, but at that point, his slugging percentage and wRC+ trailed only Mike Trout (by three points and 20 points, respectively). Alas, Gallo played just 10 games in the second half before being diagnosed with a fractured hamate in his right hand. He underwent surgery, and while he expected to be out only about four weeks, continued pain while swinging prevented him from returning at all. Read the rest of this entry »

Chosen in the ninth round of the 2018 draft, Tarik Skubal had a meteoric rise in prospect pedigree, tearing through the minor leagues in just 145 innings. He allowed just one earned run in 22.1 innings in 2018, then compiled a 2.58 ERA in high A and a 2.13 ERA in Double-A, but what caught the eye of analysts and prospect hounds alike were the strikeout and walk rates. He punched out about 40% of the batters in 2018 versus a walk rate of about 5% and posted strikeout rates of 30.3% and 48.2% in high A and Double-A, respectively, against walk rates of 5.9% and 10.6% in ’19.

Those numbers earned Skubal a place on our 2019 Tigers list before the start of that season, with Eric Longenhagen and Kiley McDaniel noting that he “dominated in pro ball after signing by throwing about 80% fastballs. He’s a ground-up rebuild who had third-round stuff at his best in college.” After he continued to dominate in 2019, Skubal climbed the 2020 version of the list, placing fourth behind three excellent prospects in their own right.

Skubal missed the entirety of the July summer camp last year but showed enough at the alternate site to earn a call-up, making his major league debut on August 18. It didn’t go to plan, though: He struck out a healthy 27.9% of batters with an 8.2% walk rate but also allowed a 72.3% fly ball rate with a 20% HR/FB ratio. That led to an ugly 2.53 HR/9 and a 5.63 ERA over 32 innings.

Unsatisfied with his 2020, Skubal made the pilgrimage to Driveline Baseball over the offseason. There, he first tried to make improvements to his existing changeup, but nixed that in favor of working on a splitter after immediately feeling comfortable with the offering used by his highly-touted teammate, Casey Mize.

Despite the new offspeed pitch, Skubal surrendered a 6.14 ERA in April despite allowing a miniscule .242 BABIP. His walk rate increased from 2020, and he was allowing even more contact in the air. And the splitter was not doing him any favors, with a pedestrian 10.2% SwStr% (the average for a left-handed pitcher’s splitter is 24.5%). He also had no control over the pitch, posting a 33.9% zone rate. Those two factors led to a .539 wOBA allowed on it.

About midway through the month, manager A.J. Hinch mentioned in a postgame press conference that Skubal would throw more breaking pitches going forward at the expense of his new splitter. That wasn’t all; he made a substantial change in terms of fastball usage after his start on the last day of April.

Baseball is cracking down on pitch-movement-enhancing substances such as, though not limited to, Spider Tack. I asked Pittsburgh Pirates GM Ben Cherington if that was a concern for his scouting staff going into this week’s amateur draft.

“We did what I think probably every team did, which was to try to learn as much as we could about whether guys were using anything, what it was, and what adjustments they were making,” replied Cherington. “We’re not naive to think that the sticky stuff was only inside professional baseball. We did some analysis on data we have from amateur pitchers in terms of spin-rate changes over time, to see if we could glean anything from that.

“Whether or not a pitcher has used anything to get a better grip on the ball is a piece of information,” continued Cherington. “But in no way does that mean… if they had to stop using something, that they can’t adjust and still be really good. These are the most talented pitchers in the world and they have a way of adjusting and finding new ways to compete and be better. So I think that it was a small piece of information that we tried to get at, but not a major driver in any decisions.”

Following up, I asked the GM about the level of pitch-analysis data they were able to get for high school draftees, including fourth-round pick Owen Kellington out of small-town Plainfield, Vermont. Read the rest of this entry »

If you’re a baseball nerd like me, you’ve likely seen this graph (or a variation of it) before:

wOBA by Launch Angle

The focus should be on launch angles between 0 and 36, or better at 8-32 degrees.

Once you get below 0 or above 36, it's hard to be productive. Again, we don't care about "average" launch angle, but the frequency you can get into the "sweet spot". pic.twitter.com/7JYOPGAd4c

Yep, it’s an illustration of how launch angle affects wOBA. And Tango’s iteration, like many others, is told through the hitter’s perspective. That makes sense – we seldom think about launch angle with respect to pitchers, since it’s trickier for them to control the contact they allow. We do know in a broad sense that there are groundball pitchers and fly ball ones, hence why metrics like xFIP and SIERA remain relevant.

But specific launch angles can also be useful in assessing pitchers. About a week ago, I shared this graph with my Twitter followers:

Here, I should clarify that what’s being measured is the year-to-year correlation of the percentage of batted balls within select launch angle ranges. What can we take away from this? It turns out that pitchers are much better at controlling the amount of extreme contact they allow. Going down the list, line drives are a capricious bunch. What we regard as standard groundballs and fly balls are a bit more manageable. When it comes to slap hits or pop-ups, though, pitchers surprisingly account for about half the variance. Go pitchers!

On Sunday, the Red Sox announced that they had extended righty reliever Matt Barnes on a two-year contract. The deal, which starts next season, will pay him a $1.75 million signing bonus along with salaries of $7.25 million in 2022 and $7.5 million in ’23. It also includes a club option for the 2024 season, valued at $8 million with a $2.25 million buyout. All told, Barnes is guaranteed $18.75 million over the term of the contract, but could earn as much as $24 million if he hits all the escalators and Boston exercises the option.

In short summary of his career, Barnes has been an effective arm since his 2014 debut. Since ’14 and through last season, Barnes was solid though not otherworldly, pitching to a 4.08 ERA, 29.9% strikeout rate, and 10.9% walk rate over 337.1 innings pitched. As with most relievers, he had his personal volatility. His best season was in 2018, when he posted a 2.71 FIP in 61.2 frames, as well as a 1.04 ERA in 10 postseason appearances en route to the Red Sox’s World Series title. On the flip side of that coin, Barnes had a comparatively tough year in 2020. He still posted good strikeout numbers but faced a bit of unluckiness with the longball, as his 1.57 HR/9 and 23.5% home run-per-fly ball rate were both career-worsts, making last season was the first time since 2015 that Barnes found himself on the wrong side of replacement level.

The Learning and Developing a Pitch series returned last month after being on hiatus due to the pandemic. Each week, we’ll hear from three pitchers on a notable weapon in their arsenal. Today’s installment features three right-handers — Scott Barlow, Aaron Nola, and Nick Sandlin — talking about their curveballs and sliders.

———

Scott Barlow, Kansas City Royals

“I have both a slider and a curveball. I’ve started to integrate the curve a lot more, whereas in the past it was a lot of sliders. It still kind of is. But they kind of work hand-in-hand, and because I’ve thrown the slider so much in the past, my curveball is probably the better story. It’s been a big learning curve as far as when to throw it.

“I messed around with a curveball a lot when I was a starter, but then as a reliever… it was kind of weird, because a lot of relievers typically have two pitches, maybe three. Coming out of the bullpen it was kind of ‘When should I throw that third pitch?’ I think the more opportunities you get, and the more hitters you face, the more you understand when to throw that pitch.

“I threw a lot of sliders and curveballs in high school, but the breaks were a lot different because the arm speed was different. But with the curveball, I had an idea of the grip I liked and I stuck with it. It just really came down to committing to it, rather than having it being ‘poppy,’ having the same arm speed as the fastball, and then kind of adjusting. When you first learn to throw it hard, you tend to spike it a lot, throw in the dirt. You kind of understand how to adjust your sight lines — where to start that fastball arm action point — so you can get it in the right location. Read the rest of this entry »
