Brad Keller and Drew Pomeranz have been bullpen stalwarts for the Chicago Cubs this season. The former made a club-high 68 appearances during the regular season and pitched to a 2.07 ERA and a 2.94 FIP over 69 2/3 innings, while the latter toed the rubber 57 times and put up a 2.17 ERA and a 3.36 FIP over 49 2/3 innings. Working primarily in setup roles, the right-left duo combined for six wins, four saves, and 39 holds. Not bad for a pair of hurlers who were essentially reclamation projects when they reported to spring training.

Now with his fourth team in the past three seasons, Keller was 9-22 with a 5.05 ERA from 2022 to 2024. Moreover, one year ago, he lost all four decisions while logging a 5.44 ERA. As for Pomeranz’s recent numbers… well, there weren’t any. Hampered by multiple arm injuries, the southpaw hadn’t taken the mound in a big league game since August 2021. At age 36, he had quite possibly reached the end of the road.

Keller’s path has included injury-related speed bumps as well. Most notable was the righty being diagnosed with Thoracic Outlet Syndrome, which required him to go under the knife after the 2023 season. Read the rest of this entry »

Water falling from the skies over Comerica Park delayed the start of a pivotal ALDS Game 3 between the Tigers and the Mariners by close to three hours. Once things dried out, Seattle’s batters rained on Detroit’s parade. Eugenio Suárez, J.P. Crawford, and Cal Raleigh all homered, and that was more than enough to support the pitching of Logan Gilbert and four Mariners relievers. When all was said and done, Seattle had an 8-4 win and a 2-1 edge in the best-of-five series.

The game started with a successful challenge. Randy Arozarena was initially ruled safe after Gleyber Torres threw to first to field a comebacker that glanced off of Jack Flaherty’s glove, but replay review reversed the call. Seattle’s leadoff hitter was out by an eyelash. A few swings later, Detroit’s starter had retired the side on just eight pitches. It was to be his only easy inning.

The Mariners made the right-hander work in the second. Josh Naylor had an 11-pitch at-bat, finally grounding out on Flaherty’s first changeup of the evening. Three other batters saw six pitches apiece. Suárez walked, Jorge Polanco and Dominic Canzone fanned, and Flaherty walked off the mound having thrown 29 in the frame, and 37 overall. It was apparent early that the Tigers bullpen would be well-worked by game’s end.

A Dillon Dingler single gave Detroit a runner in the bottom half, but as had happened in the first, Gilbert ended the mini-threat with a strikeout, leaving a Tiger stranded. Never really in trouble over the course of his outing, the tall right-hander nonetheless squelched every semblance of a Detroit rally. Read the rest of this entry »

The pitching matchup favored the Yankees. With all due respect to one of baseball’s best young arms, Toronto’s Trey Yesavage came into the contest having thrown just 14 big league innings. Conversely, New York starter Max Fried is a three-time All-Star who finished the season 19-5 with a 2.86 ERA. While Yesavage has a bright future — he’s currently the Blue Jays’ top prospect — his mound opponent seemed a better bet to perform under the pressure-packed lights of the postseason.

That didn’t happen. Yesavage, who began the year in Low-A and didn’t make his major league debut until September 15, not only kept the Yankees off the scoreboard, but he did so in spectacular fashion. As for Fried — ditto his teammates who followed him on the bump — it was a veritable horror show. He got rocked. When all was said and done, Toronto had bombarded the Bronx Bombers to the tune of a 13-7 rout that wasn’t as close as the final score suggested. The win gave the Blue Jays a 2-0 lead in the best-of-five Division Series.

That Canada’s team launched four home runs and took a 12-0 lead before the Yankees recorded their first hit — a sixth-inning single after Yesavage had left to a huge ovation — isn’t exactly a footnote to what transpired at Rogers Centre. It was an impressive onslaught. Even so, what the 22-year-old right-hander with the power arsenal did was the story of the day. Read the rest of this entry »

He doesn’t garner much press — at least not outside of Tigers territory — but Will Vest has developed into one of baseball’s better relievers. The 30-year-old right-hander has appeared in 181 games for Detroit over the past three seasons and logged a 2.93 ERA and a 2.71 ERA over 187-and-a-third innings. Moreover, he is currently the team’s closer. Vest’s 2025 ledger includes 23 saves to go with a 3.01 ERA and a 2.71 FIP, and he recorded the final out in both of the club’s Wild Card wins over Cleveland. If the Tigers go on to beat the Mariners in the ALDS, Vest will likely have played a key role.

He could easily be pitching for Seattle. As related by Dan Hubbs in a piece that ran here at FanGraphs two weeks ago, the Mariners took Vest in December 2020’s Rule-5 draft, only to return him to the Tigers the following July. Hubbs had departed as Detroit’s director of pitching development by the time Vest was reacquired, but he was, and remains to this day, bullish on the righty’s raw ability.

Vest was one of three pitchers (Casey Mize and Tarik Skubal were the others) whose development process the now-Athletics’ bullpen coach looked back on in the September 23 article. Spin rates that were “off the charts” was an attribute Hubbs saw in the then-under-the-radar prospect, as were “good movement profiles on everything he threw.” For the young hurler, success at baseball’s highest level “was just a matter of him getting comfortable competing in the strike zone.“

What are Vest’s memories of working with Hubbs, and in which ways has he continued to develop in the years that have followed? Read the rest of this entry »

Dillon Dingler is developing into one of baseball’s better catchers. Playing in his first full big league season, the 27-year-old Detroit Tigers backstop banged out 13 home runs while slashing .278/.327/.425 with a 109 wRC+ over 469 plate appearances. Moreover, he was worth six DRS and posted well-above-average framing numbers. His 4.1 WAR ranked third best among junior circuit catchers.

Dingler’s defensive chops extend to his game-calling, which is done in collaboration with Detroit’s pitching group. Preparation is a team strength — last year’s pitching chaos didn’t succeed by accident — and not just because pitching coach Chris Fetter is widely regarded as an adept game-planner. The entire coaching staff is thorough, and so too is the former Ohio State Buckeye, who squatted behind the dish in 115 games this season. (Dingler also filled in at the DH position from time to time.)

The pregame pitcher meetings that precede every game was on my mind when I sat down with Dingler on the final day of the regular season. I was primarily interested in learning how the Tigers go about them, including just what role the catchers play in the dissemination of information. What I found out is that the Tigers — ditto Dingler himself — differ somewhat from most other teams. Not having both catchers in the room, which is the common practice, is an example.

“We do it as the starting catcher, the pitcher, our catching coach, Ryan Sanko, Chris Fetter, and [assistant pitching coach] Robin Lund,” explained Dingler. “That’s pretty much it. It’s usually a smaller group.”

And then there is the preparation he does before the meeting even starts. Read the rest of this entry »

The first inning was a harbinger. The eighth inning featured an offensive explosion for a team that all too often struggles to score. The Cleveland Guardians plated five runs to break a 1-1 tie and went on to beat a thoroughly frustrated Detroit Tigers team 6-1. The season-saving rally evened the best-of-three Wild Card series at one apiece, setting up a decisive finale for tomorrow afternoon in Cleveland.

The Tigers had their chances. Make that many chances — the first of which came as fans at Progressive Field were just settling into their seats. Parker Meadows pulled a groundball into the four-hole that second baseman Brayan Rocchio could only smother, giving Detroit the first of its 17 baserunners (yes, 17) on the day. Center fielder Chase DeLauter — playing in the first inning of his first big league game — then lost a battle with the sun and wind, dropping a fly ball and giving the Tabbies an early opportunity to open up a lead. Cleveland starter Tanner Bibee survived the little-fault-of-his-own threat. Three strikeouts later, the game went to the home half scoreless.

It didn’t remain scoreless for long. Two batters in, George Valera — a rookie with just 17 major league games under his belt — took Detroit starter Casey Mize deep. It was the first of three Guardians home runs on the day, and while it gave them an early lead, it paled in importance to the two that came later.

One of the game’s biggest plays took place in the fourth inning. With the bases juiced courtesy of a Riley Greene double and a pair of free passes, Javier Báez laced a two-out single to give the Tigers a 2-1 lead… or so it seemed. Zach McKinstry was thrown out trying to go first to third, and the out was recorded just before Dillon Dingler crossed the plate with what would have been the second tally. Initially ruled safe, McKinstry was ultimately determined to be out per video review — this on DeLauter’s first career outfield assist. Read the rest of this entry »

The Cleveland Guardians are playing postseason baseball for the seventh time in the past 10 seasons, and it’s not because of a prolific offense. The low-budget AL Central club doesn’t score a high number of runs, but neither do its opponents. The Guardians allowed the third fewest runs in the junior circuit this year, and only the Houston Astros have been stingier over the past decade. Cleveland’s reputation as a pitching factory is well-earned.

How do Guardians hurlers view the organization’s pitching group, which is fronted at the big league level by pitching coach Carl Willis and includes assistants Brad Goldberg and Joe Torres, as well as bullpen coach Caleb Longshore? I recently asked that question to a quartet of Cleveland pitchers, three of whom are on the current staff, and another who was on the team prior to this summer’s trade deadline.

Before we hear their thoughts, though, it makes sense to touch on the 26-year-old right-hander who is slated to take the mound in this afternoon’s Wild Card Series opener against the Detroit Tigers. I didn’t talk to Gavin Williams about the Guardians pitching group, but I did ask him how his game has grown since we first spoke two years ago. Read the rest of this entry »

Carlos Narváez has far exceeded expectations this season. Acquired by the Red Sox from the Yankees last winter in exchange for 22-year-old pitching prospect Elmer Rodriguez-Cruz, Narváez went into spring training hoping to earn a job as Boston’s backup catcher. He did much more than that. The 26-year-old backstop went on to claim the starting job, and he heads into the final day of the regular season with 15 home runs and a 97 wRC+ over 446 plate appearances. A plus defender, Narváez has 12 defensive runs saved and 2.7 WAR.

Back in spring training, Alex Cora said something about the still-unproven — just six games of MLB experience — native of Maracay, Venezuela that caught my attention.

“He had a great offseason, playing in winter ball,” the Red Sox manager told a group of reporters, including yours truly. “Learned a lot about the offensive side of it. Very Gleyber-like as far as his swing. He can stay inside the ball and drive it.”

I stored away those quotes, thinking they might be worth revisiting if Narváez were to not only make the team, but also end up contributing with the bat. Six months later, I did just that. Reminding him of what he’d said in Fort Myers, I asked Cora if Narváez still has a Gleyber Torres-like swing. Read the rest of this entry »

Kyle Harrison is morphing into a different pitcher than the one the Red Sox acquired from the Giants as part of June’s jaw-dropping Rafael Devers deal. That was the plan when Boston brought him on board, as evidenced by the 24-year-old southpaw’s having spent close to three months in Triple-A following the swap. With 182 2/3 big league innings under his belt, the former top-rated prospect in the San Francisco system was sent to Worcester to have his repertoire reconfigured.

His primary weapons remain largely the same. Harrison still attacks hitters with a one-two combo that Eric Longenhagen called “an uphill fastball” and “a big bending breaking ball.” The former is an 94.8-mph heater, while the latter is an 84.2-mph offering that is categorized as a slurve.

And then there are the new additions.

“First and foremost, there is the cutter,” said Harrison, who has made two appearances and allowed one run over nine innings since making his Red Sox debut on September 10. “There is also a sinker that I can mix in to lefties. I have a new changeup grip, as well. Everything else is the same. The four-seam is kind of how I’ve always been identified — and I still have the slurve — so now it’s been about adding the other secondary stuff to protect it.”

Harrison mentioned adding a cutter when I spoke to him early last season, but the pitch never really took hold. Per Baseball Savant, he threw only six of them in 2024. As for the changeup, there have been multiple iterations. After tweaking his original grip last year, he is now a member of the kick change generation. Read the rest of this entry »

The Detroit Tigers are in a dogfight with just six games remaining on the schedule. Not only is their lead in the American League Central down to one game over the Cleveland Guardians — their opponent the next three nights — a Wild Card berth is no sure thing if they don’t hang on to win the division. As my colleague Kiri Oler pointed out just yesterday, while their chances are promising on paper, “the error bars on those odds are huge.” In order to stave off what could reasonably be deemed a collapse, a Tigers team that has lost nine out of their last 10 is badly in need of wins down the stretch.

A trio of pitchers who will help determine Detroit’s fate were the subject of a recent conversation I had with Dan Hubbs. Now the bullpen coach for the Athletics, Hubbs was the Tigers’ director of pitching development in 2019 and 2020, a time in which Tarik Skubal, Casey Mize, and Will Vest were all on the doorstep of the majors. Skubal (who made his major league debut in 2020) is slated to start tonight, while Mize (also 2020) will be on the mound over the weekend, and Vest (2021) has a team-leading 21 saves.

Heading into the 2020 season, Skubal was no. 4 on our Tigers prospect rankings with a 50 FV, Mize was ranked no. 2 with a 60 FV, and Vest was no. 36 with a 35+ FV. How did Hubbs view them then, and what does he see from them — albeit from a distance — five years later? That was what I wanted to know.

———

Hubbs on Tarik Skubal:

“With Tarik, it was getting him to command the arm side a little bit more. He was always kind of cross body and ran balls in on guys, and he would pitch up. He’s always had the mindset. I mean, he’s an animal on the mound, and always attacking the strike zone. So, one of the biggest things now is that he commands the arm side. But what has really changed is that he never had the changeup that he has now. That’s taken him to a whole different stratosphere. He throws 100 [mph], then he has this changeup that he can throw against [righties or lefties], interchangeably with his fastball. Read the rest of this entry »
