Kevin Kelly is proving to be yet another diamond in the rough for the Tampa Bay Rays. Acquired from the Cleveland Guardians via the Colorado Rockies in the December 2022 Rule 5 draft, the 26-year-old right-hander has since logged a 3.14 ERA and a 3.24 FIP in 73 appearances out of the Rays bullpen. Attacking the strike zone from a low arm slot, Kelly has fanned 74 batters while allowing 70 hits and just 16 walks over 86 innings.

His prospect profile was modest at best. A 19th-round pick in the 2019 draft out of James Madison University, Kelly was unranked prior to changing organizations, and going into last year he was conservatively assigned a 40 FV and a no. 27 ranking on our Rays list. Which isn’t to say that Eric Longenhagen didn’t recognize Kelly’s potential. Pointing to the side-slinger’s east-west arsenal and ability to keep the ball out of the air, Longenhagen wrote that Kelly had a chance to stick on Tampa Bay’s roster and be “a great option out of the bullpen when you need a ground ball to get out of a jam.”

Inducing worm-killers is indeed one of Kelly’s greatest strengths. Per Statcast, his 48.2% ground ball rate ranked in the 78th percentile last season, and this year he’s currently in the 91st percentile at 55.6%. And it’s not as though he doesn’t miss a reasonable amount of bats. His strikeout rate might not be anything to write home about, but at 23.0% it dwells in middle of the pack of major league hurlers.

According to Tampa Bay pitching coach Kyle Snyder, the righty reliever’s success is based on multiple factors. Read the rest of this entry »

Jordan Weems was in his 10th professional season when he was featured here at FanGraphs for the first, and heretofore only, time in July 2020. His story was one of resilience, but also of change. Then 27 years old, Weems was a converted catcher soon to make his big-league debut as a pitcher for the Oakland Athletics. Drafted by the Boston Red Sox in 2011 out of Columbus (GA) High School in 2011, he moved to the mound five years later after dwelling in Mendoza-line territory while wearing the tools of ignorance.

Weems is now in his third season with the Washington Nationals, and by and large he’s forged a decent career as a reliever. The 6-foot-4 right-hander has made 118 appearances at baseball’s highest level, and his numbers include 140 strikeouts in 130 innings. The first of his Ks came against Trevor Story, the first batter he faced while toeing a big-league rubber.

I recently asked the personable hurler if he ever thinks about that initial punch out.

“Absolutely,” replied Weems, who has a 3.94 ERA over 16 innings in the current campaign. “You have to kind of stay where your feet are in this game — what you did in the past is in your past — but at the same time, if you’d have told me early on in my [professional] career that I’d be a pitcher in the big leagues, I would have laughed. Looking back, what I’ve done is pretty cool.” Read the rest of this entry »

During spring training, I asked 10 current big leaguers how they followed the game growing up, and how that has changed since they began playing professionally. As expected, all of them noted significant differences. No longer fans following their favorite teams and players, they consume baseball in a distinctly different way, even as the mediums through which they take in the game remain much the same.

Following up on that March 8 piece, I asked a new subset of baseball professionals much the same question. Four are former players who are now managing, while two are former players who are now broadcast analysts. In each case, how they consume the game has evolved not once, but twice.

Here is what they had to say. Their answers have been edited and condensed for clarity.

John Schneider, Toronto Blue Jays manager:

“For me, it’s always been similar. That maybe sounds funny, but whether it was as a fan, player, coach, or manager, I’ve always been interested in the strategy of the game. Being a catcher, you kind of look at a game that way naturally. What most fans want to see is their favorite players — you want them to hit home runs, things like that — and then as a manager, you’re always wondering what strings another manager might pull, or at least try to pull. So, it’s similar for me, but at the same time obviously a little different. Read the rest of this entry »

Kyle Finnegan might be the most underrated closer in baseball. Flying below all but D.C. radar, the 32-year-old right-hander logged 28 saves for the Washington Nationals a year ago, and this season he has 13 saves — no one in the majors has more — to go with a 1.56 ERA. Relying primarily on a 97.3-mph fastball and an 89.8-mph splitter, he’s holding opposing hitters to a .138 average and a .259 slugging percentage in the current campaign. Finnegan’s peripherals (4.41 xERA, 4.06 FIP, 3.45 xFIP, .154 BABIP) suggest that he likely won’t remain this dominant all season, but so far, he has been on of the league’s top relievers.

His ascent to the big leagues took time. Selected in the sixth round of the 2013 draft by the Oakland Athletics out of Texas State University, Finnegan was just shy of his 29th birthday when he debuted in July 2020, seven months after he’d signed with the Nationals as a minor league free agent.

How did he go from a low-profile prospect to a high-level MLB closer?

“It’s kind of been like a slow burn for me, picking up different things and building off past experiences,” Finnegan told me prior to a recent game. “I’ve always had potential. I’ve thrown hard since I was a sophomore in college — I could run it up to 97-98 [mph] — so I really just needed the offspeed to come along. I’ve also been fortunate to be healthy throughout my career. Outside of that, I wish I could give you a rhyme or reason. I think I’ve just gotten a little better every year.” Read the rest of this entry »

Blade Tidwell has a five-pitch arsenal and a future on a big-league mound. Two years removed from being drafted 52nd-overall out of the University of Tennessee, the 22-year-old right-hander ranks among the top prospects in the New York Mets organization. “An old school power pitcher” in the words of our lead prospect analyst Eric Longenhagen, Tidwell has made six appearances for the Double-A Binghamton Rumble Ponies this year and has a 2.59 ERA, a 1.85 FIP, and 38 strikeouts in 31-and-a-third innings.

He’s developed a good understanding of his pitch metrics, a process that began when he was playing with Team USA following his 2021 freshman season at UT. Tidwell “started studying analytics” on his own, and would often discuss the subject with fellow Mets prospect Drew Gilbert, his roommate that summer. He subsequently “didn’t dabble too much into it” during his sophomore year — the Columbia, Tennessee native played just two collegiate seasons due to the pandemic — but that changed after he signed a professional contract. There was a lot more to learn… and to improve upon.

His four-seamer, which sits 94-96 mph and tops out at 98, has grown meaningfully since his amateur days. The 6-foot-4 righty got “around 14-15 inches” of ride in college, and now he gets “around 19 inches on a good day.”

Janzen Blade Tidwell — his father picked his middle name, his mother his first name — also gets good movement on his sweeper. Moreover, he can massage the movement by upping or lowing velocity. Read the rest of this entry »

Keaton Winn is a rare big league pitcher, and not just because he’s the only one who grew up in Ollie, Iowa, with a population of 201 in the 2020 census. The 26-year-old San Francisco Giants right-hander’s primary pitch is a splitter, and by a significant margin. Through seven starts this season, Winn’s usage breakdown is 42.2% splitters, 23.3% four-seamers, 20.4% sinkers, and 14.1% sliders. No starter in baseball has thrown a higher percentage of splits this season.

With one notable exception, his atypical approach has yielded good results. Winn failed to get out of the first inning when he faced the Phillies in his most recent start, on May 4, but even with that turbulent outing — five runs in 2/3 frames — he has a respectable 4.41 ERA and a 3.97 FIP. In each of the three starts that preceded the debacle, he went six innings and allowed just one run. His next start is scheduled for this afternoon against the Rockies in Colorado, at 3:10 p.m. ET.

Winn’s mix was even more splitter heavy a year ago. He made his MLB debut last June and proceeded to throw his signature offering an eye-opening 55.1% of the time in 42 1/3 innings. It’s understandable that he would prioritize the pitch — last month, our prospect writers Eric Longenhagen and Travis Ice called Winn’s splitter “devastating… one of the nastier ones in pro ball” — even if such an approach is unprecedented among starters. San Francisco’s fifth-round pick in the 2017 draft out of Iowa Western Community College is anything but ordinary in the way he attacks hitters.

Winn discussed his splitter when the Giants played the Red Sox at Fenway Park earlier this month.

David Laurila: Let’s start with your full repertoire. What was it at the time you signed your first professional contract, and what is it now?

Keaton Winn: “When I signed it was four-seam, curveball, slider, and I maybe threw like five sinkers. No changeup. Now it is four-seamer, sinker, splitter, slider.”

Laurila: You obviously throw a ton of splitters. Given how much you rely on it, would it be fair to say that you’re probably not in the big leagues right now had you never developed a splitter?

Winn: “Yeah. That’s definitely crossed my mind before. I mean, I think I ultimately could have competed to get a role, but having the splitter made it so much easier.”

Laurila: What’s the story behind it? Read the rest of this entry »

Kyle Harrison was pitching for the Double-A Richmond Flying Squirrels when he was first featured here at FanGraphs in August 2022. Then a fast-rising prospect in the San Francisco Giants system, the now-22-year-old southpaw had broken down the early evolution of his arsenal for me prior to a game at Portland, Maine’s Hadlock Field. Fast forward to this past week, and we were reacquainting at a far-more-fabled venue. Harrison was preparing to take the mound at Fenway Park for his 14th big-league start, his seventh this season.

As I’m wont to do in such scenarios, I asked the dark-horse rookie-of-the-year candidate what’s changed since our 20-months-ago conversation. Not surprisingly, he’s continued to evolve.

“I’ve added a cutter, although I haven’t thrown it as much as I’d like to,” Harrison told me. “Other than that, it’s the same pitches. The slider has been feeling great, and the changeup is something that’s really come along for me; it’s a pitch I’ve been relying on a lot. I really hadn’t thrown it that much in the minors — it felt like I didn’t really have the control for it — but then all of a sudden it clicked. Now I’ve got three weapons, plus the cutter.”

Including his Thursday effort in Boston, Harrison has thrown his new cutter — Baseball Savant categorizes it as a slider — just six times all season. Which brings us to his other breaking ball. When we’d talked in Portland, the lefty called the pitch a sweepy slider. Savant categorizes it as a slurve.

Wilyer Abreu has been one of the top rookies in baseball this season. Along with playing above-average defense in right field, the 24-year-old Boston Red Sox outfielder has logged a 155 wRC+ while slashing .316/.396/.519 over 91 plate appearances. His 1.1 WAR ranks second among rookie position players, behind Baltimore’s Colton Cowser. Granted, less than a month’s worth of games is hardly enough time to know if he’ll keep this up, but Abreu’s strong start is encouraging nonetheless.

He similarly impressed last year in a 28-game cameo. Debuting in late August, Abreu went 24-for-76 (.316) with two home runs, the exact same numbers he had this April. There’s juice in his bat. Eric Longenhagen wrote last summer that Abreu “has above-average raw power,” and the youngster’s production has backed up that prose. By the time of his call-up, Abreu had gone yard 22 times, with a 135 wRC+, at Triple-A Worcester.

His path to the big leagues included more than your typical climb up the minor league ladder. The Red Sox acquired Abreu from the Houston Astros, along with Enmanuel Valdez, in the trade for Christian Vázquez on August 1, 2022 — but that’s also only part of the story. The Maracaibo, Venezuela native had intended to sign with Boston in 2016, but the Red Sox were locked out of the international amateur market in 2016-17 as punishment for violating international-signing regulations. Abreu subsequently signed with the Astros in 2017; he waited an extra year to sign because he was told he’d get a better offer if he did.

He’s evolved as a hitter since inking his first professional contract. Read the rest of this entry »

When I interviewed Marco Gonzales in spring training 2018, the now 32-year-old Pittsburgh Pirates southpaw was with the Seattle Mariners and about to establish himself as a solid big league starter. We discussed his return to health — he’d undergone Tommy John surgery two years prior — as well as his repertoire. We also touched on his approach on the mound, a subject we’d earlier addressed in a 2014 conversation when he was a St. Louis Cardinals pitching prospect. At the time, Gonzales was your prototypical crafty lefty, and he’s remained just that throughout his career.

The former Mariners’ player rep for the MLBPA has a lot of opinions on the game he’s played professionally since 2013, when the Cardinals drafted him 19th overall out of Gonzaga University. Not surprisingly, the increase in arm injuries is of particular interest, as is the pitch clock.

Gonzales, who has since landed on the 15-day injured list with a left forearm muscle strain, sat down to discuss those topics at Pittsburgh’s PNC Park earlier this month.

———

David Laurila: We talked back in 2018 when you were with the Mariners. Are you the same pitcher now that you were then?

Marco Gonzales: “No. You’re never the same pitcher you were, even if you think you are. You might have a similar identity — you always have an identity as a player — but you change physically, emotionally, mentally. Your maturity on the mound changes. Your thought process changes, and in turn, that changes what you can do on the mound.

“The pitches I throw haven’t added or subtracted, but how I think about them, how they move, and how I’ve used them has changed a lot. Year to year, week to week, there are changes. That’s part of baseball. For whatever reason, sometimes a pitch doesn’t come out the same way it usually does and you have to use it differently, or maybe manipulate it more.” Read the rest of this entry »

Jared Jones had made just one big-league appearance when my colleague Ben Clemens wrote on April 2 that we should all get irresponsibly excited about the rookie right-hander. Little has happened to change that opinion. When Jones takes the mound this afternoon for the sixth time in a Pittsburgh Pirates uniform, he will do so with a 2.79 ERA, a 3.19 FIP, and 34.8% strikeout rate. Moreover, his fastball has averaged 97.3 mph, occasionally reaching triple digits.

Following his second start, I caught up to the flame-throwing 22-year-old at PNC Park to get a first-hand account of his arsenal and development path. Among the things I learned is that he was especially raw when the Pirates drafted him 44th-overall in 2020 out of La Mirada (CA) High School.

“I didn’t know how to pitch when I signed,” Jones told me. “I just threw fastballs, and throwing hard in high school is a lot different than throwing hard in pro ball. Guys in pro ball can hit the hard fastball, especially if you don’t have anything else.”

Jones did have secondary pitches prior to getting drafted, originally a curveball “that wasn’t very good,” and then a slider that went from “just okay” as a young prep to “pretty good” by the time he’d graduated. Even so, he was admittedly more thrower than pitcher — someone whose elite arm strength allowed him to “just throw fastballs by guys.”

Velocity came naturally to the now-6-foot-1, 180-pound righty. It also came early. “I was in my sophomore year of high school when I hit 97 [mph] for the first time,” explained Jones. “I’ve been a hard thrower for a long time.” Read the rest of this entry »
