Colton Cowser is a leading contender for American League Rookie of the Year honors, and his power numbers are among the reasons why. The 24-year-old Baltimore Orioles outfielder has 20 home runs to go with a .240/.321/.431 slash line and a 115 wRC+. San Diego’s Jackson Merrill (23) is the only rookie in either league to have left the yard more times.

That Cowser is clearing fences with some regularity is in many ways unsurprising. At a listed 6-foot-2, 220 pounds, his build is that of a basher. That said, his profile going forward wasn’t entirely clear when he was first featured here at FanGraphs in February 2022. Drafted fifth overall the previous summer out of Sam Houston State University, Cowser had propelled just a pair of baseballs over outfield barriers in 149 low-level plate appearances. Moreover, as I related to him in our offseason conversation, Baseball America had recently cited his “impressive walk-to-strikeout ratio,” adding that his swing path is “presently more geared toward contact versus power.”

The numbers suggest that Cowser is no longer the same style of hitter. After having more free passes than Ks in college and in his first taste of professional action, the left-handed-swinging slugger has fanned a team-worst 157 times this season with a 30.5% strikeout rate and a 9.5% walk rate. He’s also hitting more balls in the air, as evidenced by his 38.2 FB%. That number was just 26.9 in his two-plus years down on the farm.

Cowser’s thoughts on making less contact as he settles in to what promises to be a productive MLB career? Read the rest of this entry »

I first learned of the kick change while in Chicago for Saberseminar in late August. Chatting with Garrett Crochet and Jonathan Cannon in the White Sox clubhouse prior to a Saturday game, I heard the term from Cannon, who was describing a new pitch that one of their rotation mates, Davis Martin, had recently begun throwing. Needless to say, I was intrigued.

The following day, I learned even more about the atypical offering. Brian Bannister presented at Saberseminar that Sunday, and the kick change was one of the subjects he brought up. Moreover, the White Sox Senior Advisor to Pitching subsequently spoke about it in more detail while taking questions from the audience, this particular one coming, not surprisingly, from my colleague Michael Rosen.

As luck would have it, two opportunities to hear even more about the kick change were right around the corner. The White Sox visited Fenway Park this past weekend, and with Boston being my home base, I was able to sit down with Martin to get his perspective on the pitch, as well as the story of why and how he learned it. Then the Orioles arrived in town, so I talked to reliever Matt Bowman, who not only has something similar in his arsenal, but he also is Bannister-esque when it comes to the art and science of pitching. I spoke to the veteran right-hander about the kick change and its close-cousin relationship with the better-known split change.

Here are my conversations, lightly edited for clarity, with Martin and Bowman.

David Laurila: What is the kick change?

Davis Martin: “It’s basically for supinators. I’ve never been a pronator. It’s for guys that have really good spin talent and have always had the ability to get to that supination plane. But pronating is very unnatural for us from a physiological standpoint. Read the rest of this entry »

Statistically speaking, Joey Loperfido has gotten off to slow start in his major league career. Over his first 222 plate appearances, the lefty-hitting outfielder is slashing just .229/.281/.371 with four home runs and an 86 wRC+. Those numbers are split fairly evenly between two organizations; the 25-year-old Loperfido was traded from the Houston Astros to the Toronto Blue Jays shortly before July’s trade deadline as part of the four-player Yusei Kikuchi deal.

He’s projected to produce more than he has thus far. The Duke University product put up a .933 OPS in Triple-A prior to making his major league debut at the end of April, and as Eric Longenhagen explained in mid-June, Loperfido “has done nothing but perform since breaking into the pro ranks.” Our lead prospect analyst assigned Loperfido, who was selected in the seventh round of the 2021 draft, a 45 FV while ranking him third on our 2024 Astros Top Prospects list.

Loperfido sat down to talk hitting when the Blue Jays played at Fenway Park in late August.

———

David Laurila: Let’s start with one of my favorite ice-breaker questions in this series: Do you approach hitting as more of an art or as more of a science?

Joey Loperfido: “I think it’s somewhere in between. When you look back at it, you can see the parts that would be considered more of a science. But when you’re doing it, and as you’re feeling it, a lot of it is an art. There are a lot of calculated actions and movements, and for me that’s kind of the question of feel versus real.”

Laurila: How has that perspective evolved over the years? When you’re a kid, you’re basically just up there swinging a bat… Read the rest of this entry »

Jaden Hamm was surprised when he was selected by the Detroit Tigers in last year’s draft. That it happened in the fifth round wasn’t unexpected — he’d been projected to go in the three-to-five range — but the organization he would soon ink a professional contract with certainly was. The right-hander out of Middle Tennessee State explained it this way when I talked to him prior to a game at West Michigan’s LMCU Ballpark last month:

“I get a call [from my agent] and he’s like, ‘The Tigers are you taking you in the fifth,’” Hamm recalled. “ I was like, ‘What?’ He was like, ‘The Tigers.’ I was like, ‘I know who you said, but I didn’t expect that.’”

Subterfuge played a role in the surprise. Hamm had talked to Detroit’s area scout only a handful of times during his junior season, and while he went to the draft combine and had meetings with teams. the Tigers weren’t one of them. His best guess was that he was going to be drafted by the Arizona Diamondbacks, Atlanta Braves, or Houston Astros. That none of them — nor any other team — pulled the trigger in time has turned out well for the Tabbies. Hamm has emerged as the second-best pitching prospect in Detroit’s system, behind only shooting star Jackson Jobe.

The numbers tell a big part of the story. In 99 innings with West Michigan, the 22-year-old (as of earlier this week) Hamm has overpowered High-A hitters to the tune of a 2.64 ERA, a 3.10 FIP, a 30.6% strikeout rate, and just 73 hits allowed.

Another part of the story are Hamm’s metrics, which include 20-21 inches of vertical ride on his low-to-mid 90s four-seamer. Learning how best to employ his heater is yet another part of how he’s gone from relatively unknown to a breakout prospect. Read the rest of this entry »

The NFL season kicks off tonight, with another game tomorrow, 13 more on Sunday, and a Monday Night Football matchup set to cap off the Week One slate. Millions will be tuning in, although not everyone will be able to watch their favorite team (or keep close tabs on their fantasy football squad). Among those missing out will be the vast majority of big leaguers. At the same time that pigskin luminaries like Lamar Jackson and Patrick Mahomes are performing on the gridiron, major leaguers will be plying their trade on the baseball diamond. When you’re a professional athlete, forgoing other pastimes — watching other sports is but one of many — comes with the territory.

What is it like to miss out on things you’d be enjoying were it not for your responsibilities as a ballplayer? I asked several big league players for their perspectives on that very subject. Here is what they had to say.

George Springer, Toronto Blue Jays outfielder: “I wouldn’t ever say ‘Why do I have to play today?’ but I love football. I’m a big football fan. When the NFL gets going, and college football gets going, it’s exciting for me. A lot of it is just a break from the constant everyday grind of baseball, having a chance to go to an NFL game, to a hockey game, to a concert. Anything like that. Read the rest of this entry »

Lucas Erceg’s story is fairly well known. A position player for his first seven professional seasons, the 2014 second-round draft pick converted to the mound in 2021 and went on to make his big-league debut last May after being traded from the Milwaukee Brewers to the Oakland Athletics. The transition has been a resounding success. Now with the Royals — Kansas City acquired the 29-year-old right-hander at last month’s trade deadline — Erceg has eight saves to go with a 3.40 ERA, a 2.87 FIP, and a 27.3% strikeout rate over 50-and-a-third innings on the season.

Pitching and hitting are different animals, and that includes the data and technology used to help hone one’s craft at the professional level. With that in mind, I asked Erceg if the degree to which he is analytically-inclined has changed along with his job description.

“I’ve always been kind of minimal with that” Erceg told me prior to a game at Detroit’s Comerica Park. “I think the more I start to look at numbers, and hyper-focus on what they are telling me, the more I’ll overcorrect instead of just making those day-to-day progressions.”

Erceg feels that he was guilty of overcorrecting during his hitting days down on the farm. Looking back, he realizes that he was prone to listening to too many voices, and as a result ended up “kind of bouncing around from idea to idea, never finding consistency.” The potential — especially in the power department — was there, but he ultimately stalled out developmentally as a slugger. In his final season as a position player, Erceg slashed .219/.305/.398 in Triple-A.

Moving to the mound coincided with a mental shift for the Menlo College product. Read the rest of this entry »

Garrett Crochet has been overpowering hitters in his first season as a major league starting pitcher. In 27 outings comprising 128 2/3 innings — the woebegone White Sox have been especially cautious with his workload since the All-Star break — the 25-year-old southpaw has a 34.2% strikeout rate to go with a 3.64 ERA and a 2.83 FIP. Relying heavily on a four-seamer/cutter combination that’s augmented by a sweeper and the occasional changeup, Crochet ranks in the 92nd percentile for fastball velocity at 97.1 mph, and in the 93rd percentile for whiff rate at 32.9%.

Crochet sat down to discuss his repertoire and approach prior to a recent game at Chicago’s Guaranteed Rate Field.

———

David Laurila: Most fans are familiar with you as a pitcher. That said, how would you describe yourself?

Garrett Crochet: “I guess I think of myself as a power pitcher. I pretty much rely on two pitches, although I would like to maybe open the floor a little bit more for [additional] usage of the slider and changeup. Some outings call for that more than others, but to be honest, I haven’t gotten many reps with my changeup. It’s been difficult for me to incorporate that pitch very much in a year where I’m relying pretty much solely on efficiency. It’s been about not wanting to waste pitches. That’s why it came down to me using the fastball and the cutter primarily.” Read the rest of this entry »

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 »

Shortly before Walter Pennington was acquired by the Texas Rangers from the Kansas City Royals at last month’s trade deadline, Eric Longenhagen wrote that the 26-year-old left-hander had “caught some helium of late after striking out 35% of the hitters he’s faced in Triple-A.” Our lead prospect analyst went on to note that Pennington had recently made his MLB debut, adding that he “has a middle relief profile with little margin for error due to his underwhelming velocity.” Longenhagen assigned the 2020 non-drafted free agent out of the Colorado School of Mines a not-overly-enthusiastic 35+ FV.

Through his first seven big-league appearances — one with the Royals and now six with the Rangers — Pennington has fanned 10 batters and allowed three earned runs while attacking hitters with an array of sinkers, sliders, and cutters (he’s also thrown a smattering of four-seamers) in eight-and-two-thirds innings of work. Down on the farm, he’d heavily featured his slider while fanning 82 batters and allowing 43 hits in 63-and-a-third frames.

His velocity is indeed underwhelming. And not only has Pennington been averaging just 91.7 mph with his heaters, his arsenal doesn’t include a breaking ball that sweeps or dips in eye-catching fashion. Your stereotypical power pitcher he’s not.

Asking Pennington how he profiles on the mound elicited some intriguing answers. 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 »
