If you aren’t a Detroit Tigers fan — and maybe even if you are — you probably couldn’t name the pitcher with the lowest ERA among those who have thrown at least 150 major league innings since the start of last season. That’s understandable. The hurler in question works primarily out of the bullpen and has just six saves to go with an 8-3 record over 111 appearances during that span. He also doesn’t light up radar guns or overpower hitters. Currently ranking in the 19th percentile for fastball velocity at 91.9 mph, he has a modest 21.8% strikeout rate (as well as a minuscule 5.1% walk rate) since first taking the mound in a Tigers uniform on April 15 of last year.

The pitcher is Tyler Holton, and what he does is record outs on a consistent basis. Pitching in a variety of roles — including having been used as an opener on seven occasions — and featuring a six-pitch mix, the 28-year-old left-hander has a 2.24 ERA over 161 innings during his Tigers tenure. Making his performance even more impressive is how he ended up wearing the Olde English D. Cast aside by the Arizona Diamondbacks, the 2018 ninth-round pick out Florida State University was claimed off of waivers in February of last year.

Holton discussed his M.O. on the mound prior to a recent game at Wrigley Field.

David Laurila: Based on what I’ve seen and heard, you know how to “pitch.” Is that an accurate way to describe how you get outs?

Tyler Holton: “Yeah. That’s the simple answer. I go out there and throw strikes with multiple pitches. That’s probably the best way to put it.” Read the rest of this entry »

If you’re not a Mariners fan, you maybe haven’t noticed how good of a season Collin Snider is having. While most of the attention — at least pitching-wise — has gone to Seattle’s stellar starting rotation, the 28-year-old right-hander has quietly logged a 1.01 ERA and a 2.07 FIP over 27 relief appearances comprising 26 2/3 innings. Moreover, he has fanned 30 batters while issuing just six free passes and allowing 22 hits, only one of which has left the yard.

Snider was cut loose twice over the offseason, first by the Kansas City Royals, with whom he’d spent parts of two mostly nondescript seasons, and then by the Arizona Diamondbacks, who had claimed him off waivers. The Mariners signed him off the scrap heap in early February, and they’re certainly glad they did. The sample size is admittedly small — again, he’s made just 27 appearances — but the results have nonetheless been noteworthy. To little fanfare, Snider has been superb.

———

David Laurila: You’ve obviously taken a huge step forward this year. Did changing organizations play a role in that?

Collin Snider: “I think changing orgs had a big role in it. I had a meeting in spring training with the pitching staff here, and they showed me the difference in my numbers pitching ahead in the count and pitching behind in the count. There was a substantial difference in good results versus bad results. From that point on it was more of just, ‘Get your stuff over the plate early and often.’ My stuff plays well enough that I didn’t have to really try to do anything else after that.” Read the rest of this entry »

Tayler Scott is having a career-best season, and the primary reason is equal parts straightforward and confounding. Thirteen years after being drafted by the Chicago Cubs out of a Scottsdale, Arizona high school, and five years after making his major league debut with the Seattle Mariners, the 32-year-old native of Johannesburg, South Africa is finally featuring his best pitch. Now with the Houston Astros — his 10th big league organization — Scott has put his two-seamer in his back pocket and is throwing a heavy dose of four-seamers.

The numbers speak for themselves. Coming into the current campaign, the right-hander had made 39 big league appearances and logged a 9.00 ERA over 46 innings. This year, Scott has come out of the Astros bullpen 53 times and boasts a 1.86 ERA over 58 innings. Moreover, he has allowed just 32 hits and has a 26% strikeout rate. His seven relief wins are a team high.

Again, the four-seamer — a pitch he’d thrown sparingly in the past — has played a huge role in his success. Per Statcast, he’s throwing the pitch 47.4% of the time to the tune of a .120 BAA and a .265 SLG. Augmenting the offering is a new-ish splitter that has yielded a .122 BAA and a 184 SLG, as well as a slider (.220 BA,.339 SLG) he views as his third option.

Scott shared the story behind his fastball changeover, including why his four-seamer is so effective despite ranking in the 29th percentile for velocity, when the Astros visited Fenway Park earlier this month.

———

David Laurila: You began featuring a four-seamer this year and are having by far the best season of your career. Given that your 92.6 mph velocity is well below the big league average, what makes it so effective?

Tayler Scott: “I learned about vertical approach angle, which is guys with lower slots throwing four-seams up in the zone and creating a flatter angle for the four-seams coming to the plate. They’ve discovered that gets a lot of swings and misses. That’s when I started to throw four-seams. Over the last couple years, it was a pitch that I kind of only used late in counts to strike guys out; I would never really throw it at other times. One reason is that I tended to have a hard time locating it in the strike zone. Read the rest of this entry »

Eleven seasons after making his big league debut, David Peralta might best be described as a professional hitter. As clichéd (and definitionally daft) as that label is, it’s pretty much what the 37-year-old San Diego Padres outfielder is at this stage of his career. A reliable left-handed bat now with his fourth team — the bulk of his time has come with the Arizona Diamondbacks — Peralta is slashing .268/.327/.439 with six home runs and a 118 wRC+ in the current campaign. His career numbers are actually somewhat similar. Over 1,200 games and 4,492 plate appearances, the Valencia, Venezuela native has a .279/.334/.449 slash line to go with 123 home runs and a 109 wRC+.

Peralta talked hitting when the Padres visited Fenway Park earlier this season.

———

David Laurila: How different a hitter are you now compared to when you reached the big leagues?

David Peralta: “I’m different now, because every year, every day, you learn something to get better, how to approach the game, how to approach pitching. That’s especially true now. When I first got called up, in 2014, you didn’t see that many guys throwing 99-100 mph. Now that’s normal. So, it’s a different approach that you have to have.”

Laurila: Have there been any notable changes over the years?

Peralta: “I’ve always been more simple and short, but I tried one time in my career to change my mechanics. It worked for a little bit and then stopped working.”

Laurila: This was when?

Peralta: “In 2022, in the offseason, I started doing something different with Michael Brantley. I started hitting the way he does. Again, it worked for a little bit, but then for some reason I came off of that and couldn’t find myself again. I ended up going back to my mechanics. You have to know what type of player you are, what type of hitter you are. I know that I’m not a home run hitter. I’m a line drive hitter, so I have to work on things that way.”

Laurila: Brantley hasn’t been a home run hitter either. What was he doing that you were trying to emulate? Read the rest of this entry »

Bryce Miller has improved on his 2023 rookie season with the Seattle Mariners. Especially notable are his ERA (3.46 versus last year’s 4.32), FIP (3.70 versus 3.98), and OPS against opposite-handed hitters (.685 OPS versus .917). At the same time, many of his numbers have been strikingly similar. When I spoke to the 25-year-old right-hander at the end of July — he’s since made two starts — his win-loss record and average fastball velocity were identical to last year’s marks, as were his FB% and HR/FB%. His strikeout rate differed by just a few percentage points.

I cited those similarities to the righty, then proceeded to ask him what differentiates this season’s version of Bryce Miller from last year’s.

———

Bryce Miller: “I think that type of stuff is very similar, but the lefty-righty splits are quite a bit different. Last year, lefties batted over .300 against me. This year, it’s around .215. I think the addition of the splitter has been big, and I’ve also been locating better. If you look at the heat maps from last year, a lot of the fastballs were in the middle of the plate. This year, I’ve gotten them [elevated] a little better for the most part. So getting the heaters up and the splitters down has helped me out a lot with the lefties. That’s really been the main thing.”

David Laurila: Why is the splitter so much better than the changeup you were throwing? Read the rest of this entry »

In early April, an article titled “Astros Pitching Prospect Spencer Arrighetti Is All in With Analytics” ran here at FanGraphs, and given what the 24-year-old right-hander had to say, the headline was wholly accurate. In a conversation that took place during spring training, Arrighetti displayed nuanced knowledge of his pitch metrics while comfortably addressing topics like seam-shifted wake and vertical approach angle. He presented as a bona fide pitching nerd.

Four months into his rookie season — he made his major league debut with Houston on April 10 — Arrighetti is a nerd with an altered approach. The evolution of his M.O. has taken place over the course of an up-and-down campaign that currently has him on a high. Over his last two starts, the 2021 sixth-round pick out of the University of Louisiana at Lafayette has allowed just three runs while fanning 25 batters in 13 innings. On the year, he has a 5.14 ERA, a 4.18 FIP, and a 27.9% strikeout rate in 105 innings.

Arrighetti explained how and why his approach has changed when we sat down to chat at Fenway Park this past weekend. My first question elicited an expansive, five-minute response, after which we shared a handful of additional exchanges.

———

David Laurila: What’s changed since we talked in spring training?

Spencer Arrighetti: “I have a much better perspective now. When we talked in Lakeland, I was speaking with three big league spring training games under my belt. This is a very different game than I thought at that time. The conversation we had, as great as it was, left out a really big piece of what successful pitching is in the modern era. Obviously, shapes and velocity are really important. Arsenal design is really important. There are people who believe those are primary, but after my time up here, I’m not convinced that chasing shapes is the way to go. Read the rest of this entry »

When Dan Szymborski published his 2024 ZiPS Projections prior to Opening Day, the Kansas City Royals were penciled in for a 73-89 record and a fourth place finish in the American League Central. Coming off of a cellar-dweller season where they lost 106 games — no previous Royals team had lost more — that would have represented a clear step in the right direction.

The predicted step has materialized into a sizable stride. With two months left in the regular season, the Matt Quatraro-managed club is not only currently projected to finish with 86 wins, their postseason odds are hovering around a promising 59%, up from 13.2% at the start of the campaign. Dan hinted at that possibility in his March 27 piece. My colleague wrote that “a Royals playoff appearance would be unlikely but not unreasonably so.”

How have the Royals managed to exceed expectations? I sat down with Quatraro on the eve of the All-Star break — his team has since won nine of 13, and added Lucas Erceg, Paul DeJong, and Michael Lorenzen prior to Tuesday’s trade deadline — to get his perspective.

———

David Laurila: Your team has been better than expected. Why?

Matt Quatraro: “Pitching is the name of the game. Our starting pitching has been tremendous. [Seth] Lugo, [Cole] Ragans, [Michael] Wacha, [Brady] Singer. [Alec] Marsh, as well. They’ve taken the ball. They’ve been durable. They’ve kept us in a million games. All in all, the bullpen has been pretty solid, too. There have been some ups and downs, but they’ve weathered some storms. Read the rest of this entry »

When I first wrote about him in 2017, JP Sears was a recently drafted prospect in the Seattle Mariners system who was racking up prodigious strikeout totals in the low minors. When I wrote about him for a second time four years later, he was pitching for the New York Yankees Double-A affiliate and again punching out more than his fair share of batters. Fast forward to this season, and Sears is firmly established as a member of the Oakland A’s starting rotation. The 28-year-old southpaw came to the A’s in 2022 as part of the six-player trade deadline deal that sent Frankie Montas and Lou Trivino to the Bronx, a swap that worked out better for the woebegone West Coast club than many were expecting at the time.

Sears no longer puts up sexy numbers in the K category — his strikeout rate this season is a humble 18.1% — but the overall output has been solid. His 119 1/3 innings pitched this season are the most on the team — ditto his eight wins — and his 6.5% walk rate is indicative of a strike-thrower. The 4.53 ERA and 4.60 FIP aren’t anything to write home about, but Sears is nonetheless the best starting pitcher on the A’s.

Sears, who threw seven shutout innings on Monday against the San Francisco Giants, sat down to talk about his evolution as a pitcher when the A’s visited Boston in mid-July.

———

David Laurila: When we last talked, you were pitching in Double-A. Are you basically the same pitcher now, just three years later?

JP Sears: “Good question. I would say that I’m a lot different pitcher. I still use what kind of helped me get through the minor leagues, that being my fastball and the ability to locate it. But my arsenal has definitely gotten bigger. I’ve started throwing a sweeper a lot more — I really just learned that about two years ago — and I’ve also introduced the changeup as more of a pitch. In the minor leagues, I kind of just used it as a bait type of pitch, a show-me pitch, and now it’s more of an executed pitch that I can throw whenever. My average velo has increased a little bit, but the biggest thing would be adding to my arsenal.” Read the rest of this entry »

On July 27, 2018, a piece titled A Conversation With Oakland Pitching Coach Scott Emerson was published here at FanGraphs. Notable about the piece is that a question I’d asked about a particular pitcher, Daniel Mengden, ended up segueing into a variety of related topics. As I noted at the time, Emerson loves discussing his craft.

Six years later, that hasn’t changed. A few days before the All-Star break, I once again sat down with Emerson at Fenway Park. I wanted to ask him about pitch counts — the night before, A’s starter JP Sears threw 114 pitches across 5 2/3 innings in Oakland’s 5-2 win over the Red Sox — and expected our chit-chat would last roughly five minutes. Not surprisingly, we talked a good bit longer. Moreover — again not a surprise — we ended up discussing not just what I’d intended, but other aspects of the art and science of pitching as well.

———

David Laurila: JP Sears threw 114 pitches last night. “What is your philosophy on starters going deep into games in terms of pitch count?

Scott Emerson: “For us last night, he had an extra day of rest, and we’re also going into the break, so he’s going to have some rest there. We wanted him to get through the sixth so we could get to [Austin] Adams, [Lucas] Erceg, and [Mason] Miller. We thought that was our best chance through their lineup.

“As for me, I like starters to go as long as they can and as hard as they can. I don’t think 114 is necessarily that high of a pitch count. I thought he was throwing the ball fine. [Mark Kotsay] and I talked about it, and [Sears] felt good about himself, so we tried to get him through [Rafael] Devers. That was the goal.”

Laurila: Generally speaking, how does a pitcher’s arm action and pitching style factor into it? Read the rest of this entry »

The Toronto Blue Jays’ Matt Hague is earning a reputation as one of the best young hitting coaches in the game. Promoted to the big league staff this year after a pair of seasons spent working at Double-A, followed by a year in Triple-A, the 38-year-old former first baseman is one of the team’s two assistant hitting coaches. (Hunter Mense, who was featured in our Talks Hitting series in July 2022, is the other, while Guillermo Martinez is the lead hitting coach and Don Mattingly serves as the team’s offensive coordinator.)

Hague’s playing career included several strong seasons in the minors, but only a smattering of opportunities in the majors. The Bellevue, Washington native logged just 91 big league plate appearances, 74 with the Pittsburgh Pirates and 17 with the Blue Jays. And while what he experienced over 11 professional campaigns influences the approach he brings to his current role, what he’s learned since is every bit as important. Like most coaches who excel at their jobs, Hague is not only an effective communicator, he embraces modern training methods.

Hague sat down to talk hitting when the Blue Jays visited Fenway Park in late June.

———

David Laurila: You last played professionally in 2018. What do you know now that you didn’t know then?

Matt Hague: “Oh, man. That’s a really good question. I think the how. As a coach you’re kind of forced to unfold things that you thought as a player, but didn’t necessarily go really deep into, or didn’t have the chance to go as deep into. The importance of certain things shift on what you want to emphasize. That’s because you’re looking out for a whole group, even though it’s an individual plan, or an individual mover — a certain trait that an individual person needs to develop and continue to get better at.

“There are a lot of different pathways on how to bring out certain stuff, and the more you evolve as a coach, your perspective shifts. You try to find understandings on the mentality side, the game-planning side, the technical part of it. So yeah, I think it’s that you’re just forced to find out more. You’re forced to have a broader perspective than you had as a player.” Read the rest of this entry »
