Steven Kwan is having an outstanding rookie season with the Cleveland Guardians. The 24-year-old outfielder is slashing .297/.370/.382 with a 118 wRC+, and he’s doing so with elite plate discipline and contact skills. Kwan’s 8.8% strikeout rate ranks second to Luis Arraez’s 8.3% among qualified hitters, while his 22.6% O-Swing% is tied for sixth-best. Moreover, he’s one of only a handful of hitters with more walks (36) than strikeouts (34). As Ben Clemens wrote back in April, “Kwan’s phenomenal bat control is as real as it gets.”

A 2018 fifth-round pick out of Oregon State University, Kwan came into the current campaign having emerged as one of the game’s most intriguing young players. No. 57 on our preseason Top 100 Prospects list, the slight-of-build left-handed hitter was described as having “short levers and excellent hand-eye coordination.” Brett Gardner was cited as his closest comp.

In the latest installment of our Talks Hitting series, Kwan discusses his innate ability to put the bat on the baseball and sneeze at pitches that aren’t in the strike zone.

David Laurila: You got a lot of attention early in the season, almost exclusively for your elite contact skills. What does that mean to you?

Steven Kwan: “It’s a compliment, if anything. I think hitter success is directly correlated to strike zone management — to swinging at strikes and not chasing out of the zone. I definitely see that as a compliment.” Read the rest of this entry »

Trevor Story is an accomplished hitter. The 29-year-old Boston Red Sox infielder was a stalwart in the middle of the Colorado Rockies’ lineup prior to this season and has 173 home runs and a 110 wRC+ over six-plus MLB campaigns. Twice a National League All-Star, Story blasted 37 home runs in 2018, and he followed that up with 35 more in 2019.

His first go-round in the Junior Circuit has been of the up-and-down variety. Signed to a six-year, $140 million free-agent deal by Boston in March, Story has 15 long balls to his credit, but just a .221/.289/.423 slash line. Currently on the injured list with a hand contusion, the Irving, Texas native is expected to return to the Red Sox lineup in the near future.

Story discussed his evolution as a hitter earlier this week.

David Laurila: Nolan Arenado and Daniel Murphy, players with different approaches to their craft, were among the earliest interviews for my Talks Hitting series. [Links here and here.] Which of your former Rockies teammates are you most similar to that regard?

Trevor Story: “It would be Nolan. He was a mentor to me my first few years, and we still talk the game a lot. Nolan pretty much taught me how to pull the ball the right way. But knowing yourself as a hitter… just like Murph did. Murph knew himself, and he knew that he was going to be thinking the other way or thinking up the middle. There are obviously different schools of thinking, and I would say I’m closer to Nolan, trying to get the ball in the air pull-side.”

Laurila: What about in terms of analytics? When I spoke to them, Arenado was all about keeping things as simple as possible, while Murphy was very in-depth and detailed. Have you delved into analytics much over the years? Read the rest of this entry »

Good swing decisions are a core component of the Toronto Blue Jays’ organizational hitting philosophy. That doesn’t make the American League East club unique — every team wants its hitters to be disciplined at the plate — but the degree to which they accentuate attacking the right pitches is noteworthy. From the lowest levels of the minors all the way up to the big leagues, swing decisions are not only a focus, they’re assigned grades.

Hunter Mense has played a key role in the practice. Now doing double-duty as the big league assistant hitting coach, the 37-year-old former Florida Marlins farmhand has been Toronto’s minor league hitting coordinator since 2019.

Mense discussed the organization’s efforts to develop disciplined hitters when the Blue Jays visited Fenway Park last week.

———

David Laurila: What can you tell me about the Blue Jays’ organizational hitting philosophy?

Hunter Mense: “A lot of it has really just filtered over from 2019 and continued to build. Nothing has drastically changed. But I will say this: The things that have changed, probably — what I’ve seen up here — are some of the more important things that play in the big leagues. It’s us doing a better job of that, and learning how to develop it more in the minor leagues.”

When he was first featured here at FanGraphs three years ago, I wrote that Nestor Cortes “barely registers a blip on the national radar.” With his multiple windups in mind, I called the then-24-year-old southpaw “probably the most unique member of the 2019 New York Yankees.”

A lot has changed since that time. Cortes is still unique — the funkiness and deceptive deliveries remain part of his M.O. — but he’s otherwise a much different pitcher. He’s also become a household name. Traded to Seattle in November 2019, Cortes returned to New York in free agency prior to last season and has since been remade into one of the top starters in the American League. A first-time All-Star with a 2.63 ERA and 99 strikeouts in 95-and-two-thirds innings, Cortes attacks hitters with a different arsenal than the one he employed as an obscure reliever.

How has Cortes evolved, and just as importantly, can he continue to thrive if he doesn’t evolve further? Yankees pitching coach Matt Blake addressed those questions when the team visited Fenway Park earlier this month.

———

David Laurila: You’ve obviously been asked about Nestor Cortes numerous times already this season. That said, why has he been so good?

Matt Blake: “When he first started going last year, the league didn’t really know who he was. I mean, they knew of Nestor, but they hadn’t necessarily seen this version of him, where there’s a little bit more velocity [and] the fastball has kind of a true riding profile, one that’s a little bit closer to cut than run. And then the cutter off of that creates a really tough visual for hitters to identify. He’d also added the sweeper slider to be able to slow guys down and steal some strikes.

Robert Gasser is emerging as one of the most promising pitching prospects in the San Diego system. Over his last six starts with the High-A Fort Wayne TinCaps, the 23-year-old southpaw has fanned 47 batters while allowing just six earned runs in 36-and-two-third innings. On the season, Gasser has a 3.76 ERA to go with a 3.09 FIP; the latter is the third-best mark in the Midwest League.

He isn’t the same pitcher the Padres drafted 71st overall last summer out of the University of Houston. Gasser still throws from a low three-quarters slot, but his arsenal has changed, and to a certain extant, so has his attack plan. Armed with a more diverse mix that includes tweaked grips, the 6-foot-1 El Dorado, California native doesn’t believe in being bland.

Gasser — No. 14 on our San Diego Padres Top Prospect list — discussed his evolving arsenal in late June.

———

David Laurila: What is your M.O. on the mound? In other words, how do you get guys out?

Robert Gasser: “Honestly, just keeping them off balance. I think that’s the most important thing for me. Throwing all of my pitches in the strike zone consistently gives me an opportunity to miss barrels while I’m changing speeds and location.” Read the rest of this entry »

Jay Groome has experienced a lot of ups and downs since being drafted 12th overall by the Boston Red Sox out of a New Jersey high school in 2016. The now-23-year-old southpaw had Tommy John surgery in 2018, and his career mark as a professional includes an 11-22 record with a 4.50 ERA over 240 innings.

Groome’s future nonetheless remains promising. Ranked 13th on our Red Sox Top Prospects list coming into the current campaign, the 6-foot-6, 265-pound former first-rounder has a 3.52 ERA and has allowed just 58 hits (with 81 strikeouts) in 76-and-two-thirds innings with the Double-A Portland Sea Dogs. Moreover, he has a more diversified arsenal and a better feel for how to attack hitters than he’s had in previous seasons.

Groome discussed his evolution as a pitcher, and the hurdles he’s overcome along the way, earlier this summer.

David Laurila: When I first interviewed you in 2017, I asked where you were in terms of transitioning from a thrower to a pitcher, and your response was that you “100% know how to pitch.” Looking back, how accurate was that?

Jay Groome: “That was probably just my younger self trying to be honest. But I’ve added two more decent pitches since then, and I’m trying to throw all of them in the zone. I can fairly say now that I’m pitching a lot more than throwing.” Read the rest of this entry »

Jason Foley has emerged as one of the most reliable members of the Detroit Tigers bullpen, and learning that his four-seam fastball profiled poorly is a big reason why. The 26-year-old right-hander switched to a sinker, and the results speak for themselves. Since debuting with Detroit last June, Foley has a 2.79 ERA and a 3.54 FIP over 36 relief appearances comprising 38-and-two-thirds innings. Throwing his worm-killer 53.9% of the time, he’s logged a 55.3% groundball rate.

Foley, whom the Tigers signed out of Sacred Heart University in 2016, discussed his career-changing repertoire tweak at Fenway Park in late June.

———

David Laurila: You’ve gone from a non-drafted free agent out of a low-profile college program to a pitcher performing at a high level in the big leagues. How did that happen?

Jason Foley: “I get asked that quite a bit, like — ‘You weren’t good enough to get drafted, so how are you now here?’ — and I think a lot of people are looking for one magic answer, or maybe one magic change that I’ve made. But neither of those are true. It really just stems from hard work and consistency, and from all of the little things that help you get 1% better every day.” Read the rest of this entry »

Darick Hall was an under-the-radar prospect when he was first featured here at FanGraphs in June 2018. A 14th-round pick two years earlier out of Dallas Baptist University, the 6-foot-4, 235-pound first baseman went into that season unranked. That part of his profile hasn’t changed. Hall logged a 101 wRC+ in Triple-A last year, and came into the current campaign once again absent from most prospect lists.

He’s proceeded to crush expectations. The now-26-year-old slugger earned his first big league call-up on Wednesday, this after bashing 20 home runs with a 132 wRC+ at Triple-A Lehigh Valley. Last night, in just his second game, Hall launched a pair of home runs in a 14-4 Phillies win over the Atlanta Braves.

Hall discussed his evolution as a hitter late in spring training.

———

David Laurila: How have you evolved as a hitter since we talked four years ago?

Darick Hall: “It’s changed, but at the same time, it hasn’t changed much. I had been learning how to hit line drives more. Coming into pro ball, if the ball wasn’t up, I would drive it into the ground, because I would come over the top. Through the years, I’ve learned how to… I have a flat path, right? I don’t really have that vertical barrel, up through, so I had to learn how to use my legs to go down and get level with that ball to where I can hit it on a line. Obviously, sometimes I’ll drive it up for [home runs].” Read the rest of this entry »

George Kirby is off to a solid start in Seattle. Since debuting with the Mariners in early May, the 24-year-old rookie right-hander has a 4.04 ERA and a 4.73 FIP (numbers that were markedly better before last night’s career-worst outing) to go with 49 strikeouts in 53 innings. Lending credence to scouting reports — our Eric Longenhagen lauded not only his high-octane heater, but also his plus-plus control — Kirby has issued just seven free passes.

Drafted 20th overall in 2019 out of Elon University, Kirby ranked No. 3 on our 2022 Seattle Mariners top prospects list. Kirby discussed his early career development, including what he’s learned from analytics, earlier this month.

———

David Laurila: You’ve had access to a ton of information playing in the Mariners’ system. What are some of the ways you approach pitching differently than you did just a few years ago?

George Kirby: “One thing I’ve really tried to hammer on is being location-based. I look at the analytics for certain pitches. With my slider, for instance, there is my release point and the horizontal movement. There are good tools to see where you’re at and kind of how to manage your off-speed. I’m always looking at that stuff.”

Laurila: By location-based, I assume you’re referring to how your pitches play best in certain zones?

Kirby: “Yes. With the Mariners, we have our ‘green clouds,’ which show the best pitch in that location in certain counts. I try to really focus on that. And one of the biggest numbers is that 94% of the time when you throw a first-pitch strike, you’re either getting the ball back 0–1 or it’s an out. That’s a huge part of pitching — not being scared of the zone and allowing that first pitch to work in your favor.” Read the rest of this entry »

Brendan Donovan knows who he is as a hitter. The St. Louis Cardinals rookie is at his best when he’s hunting line drives, and that approach has been working like a charm. Two months into his big-league career, the 25-year-old is slashing .315/.426/.448 — with 14 doubles and one home run — in 197 plate appearances. Moreover, his 146 wRC+ is tops among qualified first-year players.

A left-handed hitter whom the Cardinals selected in the seventh round of the 2018 draft out of the University of South Alabama, Donovan is coming off a 2021 season that saw him climb from High-A to Triple-A, then excel in the Arizona Fall League. That meteoric rise continued this spring. Donovan earned a promotion to St. Louis in late April, and all he’s done since arriving is spray line drives. It’s what he does.

Donovan discussed his swing and approach when the Cardinals visited Fenway Park earlier this month.

———

David Laurila: How have you developed as a hitter since coming into pro ball?

Brendan Donovan: “We made a change in our hitting department — Jeff Albert, Russ Steinhorn, and those guys came in — and I was someone that made contact, but it wasn’t always quality contact. What we did is put me into a better body posture, better positioning, more tilt over the plate. I learned how to load the back hip a little better and flatten out my path. From there, it’s basically, ‘Let’s just try to get on plane, and see how long we can stay on plane.’ That’s helped me with fastballs up, and given me more adjustability on breaking balls and changeups, because I’m in the zone longer.
