Arsenals that include three variations of a fastball — four-seamer, two-seamer, cutter — are increasingly common in today’s game, and Drew Rasmussen is among the trend’s success stories. Relying heavily on a triad of heaters, the 30-year-old Tampa Bay Rays right-hander boasts a 2.96 ERA and a 3.65 FIP over 249 1/3 innings across the 2025-2026 campaigns. Moreover, he just represented the Rays on the American League All-Star team for a second year running.

How Rasmussen became three-heater reliant (just over 80% combined usage) isn’t itself atypical. The way he tells the story of how it happened is atypical… if not a bit curious. In explaining the advent of his most recent — and most impactful — fastball addition, he pinpointed a hitter against whom he’d struggled far less than his telling would suggest.

Rasmussen sat down to talk fastballs when the Rays visited Fenway Park over the weekend. As his responses were expansive — followup questions were few and far between — what he shared is being presented in monologue form.

Drew Rasmussen: “When I got traded here [in May 2021], I was four-seam and gyro slider — that’s basically what I was throwing in Milwaukee — and then I had a curveball that was very low usage, as well as a bad, bad changeup. Over here, when they transitioned me from the bullpen into the rotation, we learned that I can manipulate the gyro slider a little bit to create a little more lift and give it more of a true cutter profile. I can also manipulate it to get some depth and keep a true slider profile, which gives me the opportunity to pick and choose shapes depending on what I’m looking for. Situationally, what do I want to throw?

“They saw the movement profile of my changeup, so we scrapped that pretty quick. From there we started developing a sweeper — I have the ability to supinate through everything — and that worked pretty well for me in 2021. Then, in 2022, I kept running into Bo Bichette. I had nothing to get him out with. Nothing. I mean, he’s good at hitting balls the other way, and staying on everything. But if you missed in with a breaking ball, he could do pull-side damage. I would be out there frustrated, because the only thing I had to go in on him with was a four-seamer. And at the time, I was cutting it anyway.

“We started playing around with things. Because I had nothing that would work [inside] to him, we would take a shot with a four-seam up and away and he would hit a double into the gap. We would take a shot with a gyro slider down and away, and he would hit it through the four hole. We’d go sweeper and he’d shoot something down the line. I’d try to bounce a curveball and he would hit a line drive up the middle. Everything I threw worked right into his comfort zone, basically. Read the rest of this entry »

Troy Melton has excelled since returning to the mound in late May. Over nine starts comprising 55 innings, the 25-year-old Detroit Tigers right-hander has won five of six decisions while logging a 1.80 ERA and a 3.86 FIP. Sidelined for the initial two months of the season due to elbow inflammation, he is back to being one of baseball’s most-promising young pitchers.

What most stands out about Melton’s campaign to date? From an arsenal perspective, the answer has to be his cutter. Last season, he threw the pitch at a 10.8% clip to the tune of a .368 BAA and a 12.8% whiff rate. This year, the offering has elicited a .083 BAA and a 26.0% whiff rate while being thrown at a nearly-double 20.5% clip.

Why the increased reliance on his cutter, and why has it been so effective?

“I didn’t really change anything, which is the weirdest part,” Melton told me in the days leading up to the All-Star break. “I’ve just been throwing it way, way harder and getting a lot of swing-and-miss. I’ve been throwing my slider harder, too. I got one up to 91 [mph] in my last start, which is well above what I’d been doing previously.

“It’s definitely interesting,” the second-year big-leaguer continued. “It’s not even something I consciously changed, it’s just that I’ve had a little bit more intent. I realized that my intent wasn’t high enough, so I literally started trying to throw harder, and that didn’t sacrifice any execution. I’ve been executing just as good, if not better. My cutter has been kind of been the leading beneficiary of that.”

In terms of velocity, Melton’s cutter is averaging 92.2 mph, up from 90.9 mph in his rookie campaign. Locating the pitch better has likewise been a factor in its success, as has its role in his attack plan. Read the rest of this entry »

Gage Jump is no. 73 on The Board and no. 2 on our Athletics prospect rankings. Moreover, he is now a big leaguer. Called up from Triple-A Las Vegas in late May, the 23-year-old southpaw has since made nine starts and logged a 3.51 ERA, a 3.31 FIP, and a 23.5% strikeout rate over 48 2/3 innings. Selected in the second round of the 2024 draft out of LSU, he debuted professionally last season and played at both High-A Lansing and Double-A Midland.

His pitching knowledge stands out nearly as much as his plus raw stuff and what our lead prospect analyst Eric Longenhagen described back in April as a “super short arm action.” Jump is studious about his craft, and he has been since his days as a San Juan Capistrano prep player. Prior to joining the collegiate ranks, he was rated as the top left-handed pitcher in the state of California.

Jump discussed his data-influenced approach to pitching when the A’s played in Detroit this past week.

David Laurila: What have you learned about pitching — specifically about yourself as a pitcher — since coming to pro ball?

Gage Jump: “Interesting. That’s a tough question. I would say that I was very fortunate to go to a good private school, and that when I was young I was introduced to things like Plyo balls and Rapsodo. Our head coach at JSierra [Catholic High School] brought out Kyle Boddy [from Driveline]. I wasn’t a big kid and wasn’t throwing very hard, so I wanted to understand what everything meant and how to get the ball to move a certain way. Of course, just because I know certain things doesn’t mean I’m able to make them happen, which is why I think pitching is so much fun. You’re always trying to develop and get better, and while you could know the answers, it’s still super hard to put your hand in a certain position, know where your body is at, and get [the results] you want.

Tarik Skubal started a spring training game I attended back in March — I believe it was in Dunedin — and something he said following the outing caught my attention. Speaking to a small group of reporters, the Detroit Tigers southpaw said “Ding was really creative back there today. I loved the pitch mix. I felt like he was using every weapon we needed.”

I asked Skubal if he could elaborate.

“I don’t know to explain it other than the flow was great,” he replied. “Mixing spin in counts where we typically don’t throw spin, then going to back to spin to get to the changeup. I felt like he was in control today. He was pressing the right buttons and I was synced up. It’s part of the sport where things happen subconsciously.”

Ding is, of course, All-Star catcher Dillon Dingler. Four months after Skubal spoke those words, I had an opportunity to ask the backstop how he would describe creativity within the framework of game-calling — not just when the Tigers ace is on the mound, but for the staff as a whole.

“You’re not going to try to recreate the wheel,” replied Dingler, whose diligent game prep is well-chronicled. “You’re going to stick with strengths, so it’s about finding different avenues to get to those strengths. That could be spinning in certain counts, spinning early, not showing the fastball until later. Then, once they’re on the fastball you can go changeup or to something else. There are a bunch of different avenues to get to the final result. Read the rest of this entry »

Tuesday night’s outing wasn’t anything to write home about — four hits and five runs allowed over 5 2/3 innings in a 6-3 Washington Nationals loss to the Houston Astros — but Andrew Alvarez is having a good season. Across 12 appearances, including six as a starter, the 27-year-old southpaw from Los Alamitos, California has tossed 47 frames with a 3.64 ERA, a 2.97 FIP, and a 25.4% strikeout rate. Pitching in his first full big league season, he has been one of the few bright spots on a staff that is statistically among the worst in the majors.

Velocity isn’t his carrying tool. At 92.3 mph, Alvarez’s fastball ranks in just the 18th percentile for velocity. What the 2021 12th-round pick out of Cal Poly brings to the table is a five-pitch arsenal that leans heavily on a somewhat atypical breaking ball combination. In terms of usage, his mix has been 29.8% four-seamers, 28.7% curveballs, 24.7% gyro sliders, 13.9% sinkers, and 2.9% changeups.

The left-hander’s self-identity as a pitcher pretty much mirrors his profile.

“The Nationals have certainly helped me grow my game and understand who I am,” Alvarez told me prior to a recent game. “I’m not someone who is going to overpower you with stuff, but rather keep you off balance, get some weak contact and a little bit of chase here and there, a little bit of swing-and-miss. For me, it’s more about moving the ball around, changing speeds and locations, and [getting] a lot of groundballs”

Alvarez’s 57.1% groundball rate is tied for sixth highest among hurlers with at least 40 frames on the season. Moreover, his chase rate (57th percentile) and whiff rate (65th percentile) are both comfortably above league average.

And again, Alvarez’s breaking ball combination is atypical, as well as his primary attack plan against most hitters. Read the rest of this entry »

Will Warren has come a long way since the New York Yankees selected him in the eighth round of the 2021 draft out of Southeastern Louisiana University. He has also made big strides since he was first featured here at FanGraphs following a 2022 season that saw him reach Double-A. Discovering that his four-seam fastball is a viable weapon is a big reason why. When I interviewed Warren four years ago, his preferred offerings were a sweeper and one-seam sinker.

His numbers in the current campaign are rock solid. Building on a 2025 first full big league season in which he went 9-8 with a 4.44 ERA, the 27-year-old right-hander has toed the rubber 17 times to the tune of a 3.73 ERA and a 3.57 FIP over 89 1/3 innings. Further establishing himself in the Yankees’ starting rotation, he counts seven wins among his 10 decisions.

How and why did Warren go from a hurler who relied heavily on a sinker-sweeper combination to one who aggressively attacks batters with a 93.7-mph four-seamer? Read the rest of this entry »

Recent Sunday Notes columns have included soccer segments with Jake Burger (Tottenham Hotspur) and Tommy Kahnle (Bayern Munich) discussing their respective allegiances, as well as their thoughts on the World Cup. This week we’ll hear from Sean Doolittle. The Washington Nationals’ assistant pitching coach is a devoted fan of Leeds United.

“It really kind of took off in 2020,” explained Doolittle, who prior to joining the coaching ranks made 463 relief appearances while playing for four teams, primarily Oakland and Washington, from 2012-2022. “Harvey Sharman, our director of medical services — the head of our training staff group [with the Nationals] — was a “physio” at Leeds for 15 years before he came to the states. I learned a lot about the club from him. Before that I was more of a casual soccer fan, playing a lot of FIFA on Xbox.

“They were in the Championship,” continued Doolittle, referring to England’s second-tier league. “They started up before us after the shutdown, and I remember watching those games and kind of jumping on the bandwagon. They won and got promoted to the Premier League. I was hooked after that. It’s since been an up-and-down couple of years, but last season [a mid-table finish] was really fun.”

Doolittle told me that his Leeds allegiance “isn’t super-influencing” the way he has been watching the World Cup, although he is very much aware of how the team’s players — four in all — have been faring on the sport’s biggest stage. He cited how Gabriel Gudmundsson (Sweden), Ao Tanaka (Japan), and Crysencio Summerville (Netherlands) have all seen their countries eliminated, while Brenden Aaronson still has a chance to hoist a trophy with Team USA.

Dan Shulman was featured here in Sunday Notes on June 21, the topic being broadcast traits he shares with his son Ben, who calls Toronto Blue Jays games on radio. Today we’ll hear from the TV play-by-play voice of “Canada’s Team” on non-familial matters, primarily how a club’s fortunes influence tone in the booth. The elder Shulman has been behind the mic in both good times and bad, but does the number of wins and losses — be they over a multi-week stretch or a much longer span — actually matter in terms of a broadcaster’s style?

Shulman addressed that subject, and more, on a recent visit to Fenway Park.

David Laurila: How well a team is doing impacts the mood of a fanbase. To what extent does it — or should it — influence how the games are called?

Dan Shulman: “I think every broadcaster has their own internal balance. Some sway more positive. Some sway more neutral or objective. My job is to keep people interested in watching the team, whether they’re playing well or they’re not playing well, but you certainly can’t have entirely the same tone when the team is having a bad year, as opposed to when they’re having a good year. In 2024, the Blue Jays finished last. In 2025, they made it to the World Series. The tone is very different.

“You do always try to find some positives. In 2024, after the deadline, they traded off a bunch of guys and had some younger players coming up who did pretty well and were interesting. You focus on that a little bit. But again, the overall tone is different. You can’t sugarcoat everything. You have to be pretty honest with the viewers. At the same time, you can’t go on the air and say, ‘This is bad; none of these players belong here.’ That’s not how the job is done.”

Laurila: Basically, it is fair to be critical, but only to a point… Read the rest of this entry »

Woo-Suk Go was one of Korea’s top closers from 2019-2023. Over that five-season span, the 27-year-old right-hander logged 137 saves and a 2.39 ERA across 275-and-a-third innings with the LG Twins. Moreover, his 29.3% strikeout rate was the highest among KBO hurlers who threw at least 200 frames.

He hasn’t had nearly as much success since coming stateside. Signed as an international free agent by the San Diego Padres in January 2024, Woo-Suk was subsequently swapped to the Miami Marlins four months later in the Luis Arraez deal, only to be released in June 2025 and picked up by the Detroit Tigers. His inability to gain a foothold is reflected in the numbers. He entered the current campaign having recorded just six saves and a 5.61 ERA over 75 appearances down on the farm.

This season has been an another story. Looking more like the pitcher who dominated KBO hitters, Woo-Suk boasts a 2.06 ERA, a 2.26 FIP, and a 35.1% strikeout rate over 39-and-a-third innings across 25 appearances, eight with Double-A Erie and 17 with Triple-A Toledo. Working most often in a setup role, he is 3-1 with three saves.

Results aside, how does he differ from the young pitcher who excelled in his homeland? Read the rest of this entry »

Max Clark is among the top position player prospects in baseball. Three years removed from being drafted third overall by the Detroit Tigers out of the Indiana’s Franklin Community High School, the left-haded-hitting 21-year-old outfielder has been described by our prospect team as having “a mature blend of tools and skills that belie his young age,” as well as a “feel to hit [that] stands out.” Clark is currently holding his own as one of the youngest players in Triple-A. Over 310 plate appearances with the Toledo Mud Hens, he has 22 extra-base hits, including six home runs, to go with a .264/.346/.394 slash line and a 100 wRC+.

In the latest installment of our Talks Hitting series, Clark discusses his approach at the plate, as well as developmental strides he has made since coming to pro ball. My conversation with the 60-FV prospect took place prior to Wednesday’s Mud Hens game in Worcester, Massachusetts.

David Laurila: How would you describe yourself as a hitter?

Max Clark: “I’m definitely a feel-for-hit guy. I have developed more power over the last couple years, obviously from growing up, but also from understanding where to do damage on which pitches and in which counts. Overall, I’m just going to hit. I’m going to put the ball in play. I hate striking out; I absolutely despise it. So, I want to put the ball in play and let my speed tool work, steal bases, cause chaos. But when I get a pitch in the damage zone, I’ll take a rip.” Read the rest of this entry »
