Tigers Place Reese Olson On Injured List

By | at

The Tigers placed Reese Olson on the 15-day injured list due to right ring finger inflammation, as first reported by Chris McCosky of The Detroit News. Reliever Chase Lee was recalled from Triple-A Toledo in a corresponding active roster move.

Detroit will temporarily operate with a nine-man relief group and four starters. McCosky adds that they’ll push Jack Flaherty’s start back to what would have been Olson’s turn on Thursday against the Guardians while deploying a bullpen game on Wednesday in St. Louis. The Tigers are three games into a nearly two-week stretch without an off day, so there aren’t upcoming opportunities for their starters to work on regular rest in a four-man rotation.

Olson’s injury comes as a surprise. He looked sharp as ever during Saturday’s start in Toronto, firing six scoreless innings in an eventual 2-1 loss. He sat north of 95 MPH with both his four-seam fastball and sinker, slightly above his season average. It’s not clear if the soreness arose during that start or in the past two days, but it’s evidently enough to shelve him for at least two weeks.

The 25-year-old Olson has somewhat quietly emerged as one of the better young pitchers in the sport. He owns a 3.60 ERA over parts of three seasons and is out to a career-best start. Olson carries a 2.96 earned run average across 48 2/3 innings. He’s striking out more than a quarter of opponents while getting grounders on half the batted balls he allows. Olson has reeled off four scoreless appearances through his first nine starts. He could be in the mix for his first career All-Star selection if this injury proves minor.

At 31-16, the Tigers have MLB’s best record. Olson, Tarik Skubal and Casey Mize each carry sub-3.00 ERAs, helping Detroit to a 3.39 rotation earned run average that ranks fifth in the majors. Mize went down with a hamstring strain a couple weeks ago, while they’ve been without Alex Cobb all season due to a right hip issue. Skubal, Flaherty, Jackson Jobe and Keider Montero comprise A.J. Hinch’s current four-man starting staff. McCosky writes that Mize could be activated from the IL by the weekend.

Tigers Place Casey Mize On 15-Day Injured List

By | at

The Tigers announced right-hander Casey Mize is being placed on the 15-day injured list due to a strained left hamstring. Right-hander Chase Lee is being recalled from Triple-A Toledo to replace Mize on the roster. As noted by Evan Petzold of the Detroit Free Press, manager A.J. Hinch told reporters that the strain was “very mild.” Cody Stavenhagen of The Athletic adds that the issue initially cropped up during his last start against the Rockies, but that it was initially believed to be dehydration.

Given the mild nature of the issue, it’s reasonable to think that a reasonably quick recovery could be on the table for Mize. With that said, Petzold points out that Mize has had issues with his left hamstring before and ultimately ended up missing two months due to the issue last season. Given that previous injury history, it would hardly be a surprise if the Tigers ended up being cautious with Mize’s hamstring. He’ll miss at least the next two weeks due to the issue in any case, but even mild hamstring strains can leave pitchers away from the big league mound for a month or longer.

Losing a pitcher from the starting rotation is always worrisome, but it’s especially disappointing for Mize and the Tigers given the former first-overall pick’s strong start to the 2025 campaign. After throwing just 112 1/3 innings from 2022 to 2024 due to a number of injuries and struggling to a middling 4.57 ERA even when healthy enough to pitch, Mize entered the 2025 season without any assurances of a starting role. He managed to make the club’s Opening Day rotation despite that, however, and has looked excellent in seven starts this year with a sparkling 2.53 ERA across 42 2/3 innings of work. That level of dominance isn’t quite supported by the advanced metrics, as Mize is striking out just 21.0% of his opponents with a 3.93 FIP and 3.81 SIERA, but even those less impressive numbers would be a big step forward for the right-hander if carried forward across a full season.

Now that Mize’s attempts to put together a quality season in the middle of the Tigers rotation are on hold for the time being, Detroit will need to find a way to replace his production in the rotation. Mize was next slated to start for the Tigers on May 13, so a decision won’t be necessary for another few days. Right-hander Alex Cobb threw a live, two-inning bullpen session yesterday that lasted 30 pitches, but isn’t expected to be ready to return from hip inflammation until later this month. Matt Manning and Keider Montero are both on the 40-man roster with starting experience in the majors; Montero’s last start was the same day as Mize’s start against Colorado, while Manning’s came the day prior. That means either righty would be on full rest and able to take the ball if necessary. If the Tigers don’t want to turn to either Montero or Manning as a starter, they’ll likely be left forced to go with a bullpen game against the Red Sox this week.

Fortunately for the Tigers, they’ve gotten generally strong production from the rest of their rotation this year that should help them weather the loss of Mize. Tarik Skubal looks every bit like the reigning AL Cy Young award winner after winning the pitching triple crown last year, Reese Olson has built on an excellent 2024 season with strong numbers again this year, and Jack Flaherty has looked solid even if he isn’t quite as dominant now as he was in his first stint in a Tigers uniform last year. The only slot in the rotation that’s currently providing the club below-average production is that of top prospect Jackson Jobe, but even he had a solid 3.38 ERA before he was torched for six runs in 3 2/3 innings at Coors Field during his last start. As for Lee, the 26-year-old righty made his big league debut with Detroit earlier this year and pitched to a 1.42 ERA in six appearances with six strikeouts against three walks.

The Tigers’ Rotation Camp Battle

By | at

The Tigers expected to enter Spring Training with four rotation spots secured. Jack Flaherty’s surprisingly quiet market allowed Detroit to reinstall him as the #2 starter behind Tarik Skubal. Righty Reese Olson filled that role down the stretch last year after the Tigers traded Flaherty to Los Angeles. Free agent signee Alex Cobb would’ve had a mid-rotation role in his own right.

It didn’t take long for an injury to intervene. Cobb is battling inflammation in his right hip, which is likely to lead to a season-opening injured list stint. It’s an alarming start to his Detroit tenure, as the veteran righty missed a good portion of last year rehabbing a 2023 labrum repair in his opposite hip.

What had been a camp battle for one spot expands to a competition for two vacancies. Detroit has a handful of recognizable names — including a few one-time top prospects who are still looking to establish themselves — in the mix for those jobs behind the Skubal/Flaherty/Olson top three.

Jackson Jobe

Aside from Roki Sasaki, the 22-year-old Jobe may currently be the sport’s most talented pitching prospect. Baseball America, Kiley McDaniel of ESPN, and MLB Pipeline each placed him as their #2 pitching prospect. Keith Law of The Athletic ranks Jobe as the #1 pitching prospect — Law excluded Sasaki from his ranking based on the latter’s NPB experience — while Eric Longehagen of FanGraphs had Jobe behind Sasaki and Andrew Painter.

Evaluators agree that Jobe has top-of-the-rotation ceiling. He’s the most exciting player in this group, but he’s far from a lock to break camp. The 6’2″ righty’s MLB experience consists of four relief appearances — two apiece in the regular season and playoffs — last fall. He has started all of two Triple-A games.

Jobe spent most of last season at Double-A Erie, where he turned in a 2.36 ERA with a 27% strikeout rate but walked nearly 13% of opposing hitters. He missed two months because of a hamstring strain. Last year’s 91 2/3 innings nevertheless represented the most he’s thrown in a professional season. Even if he breaks camp, he’s unlikely to make 30+ starts and top 150 innings. The Tigers surely don’t want to burn him out early in the year. Jobe still has a full slate of options and could begin the year with Triple-A Toledo.

Casey Mize

The first overall pick in 2018, Mize is now a few seasons removed from being one of the game’s top pitching prospects. The 27-year-old’s body of work has been decent but underwhelming relative to expectations. Mize pitched to a 3.71 ERA over 30 starts in 2021, his first full season. Tommy John surgery essentially cost him the next two years. The Auburn product returned to action with a 4.49 ERA across 102 1/3 frames last year. He showed plus control and got a lot of ground-balls but managed only a 17.3% strikeout rate.

Mize hasn’t missed many bats and gave up a lot of hard contact last season. He’s still sitting in the 95-96 MPH range with his fastball, but none of his top four offerings (four-seam, slider, splitter, sinker) got especially strong results last year. It looks like he’s trending towards a fifth/sixth starter role. Mize still has a full slate of options, but he’s 61 days away from reaching five years of service time. At that point, he cannot be sent to the minors without his approval. He’s making $2.34MM and under arbitration control for another year beyond this one.

Kenta Maeda

The Tigers inked Maeda to a two-year, $24MM free agent deal last winter. It looked like a good value at the time, but the veteran righty had a terrible first season in the Motor City. Maeda allowed more than six earned runs per nine across 112 1/3 innings. He struck out just 19.8% of batters faced, a huge drop from the 27.3% mark he’d posted during his final season with the Twins. His home run rate climbed for the fourth consecutive season.

Maeda lost his rotation spot last July. He worked in long relief until the final weekend of the season, when he picked up a spot start after Detroit had punched its postseason ticket. Detroit left him off their playoff rosters. While Maeda was essentially a non-factor by season’s end, president of baseball operations Scott Harris said early in the offseason that the Tigers would give him another chance to earn a rotation spot out of camp. The Tigers kept him on the roster all offseason, suggesting they’re still holding out some hope that they’ll get something positive from what’ll be a $10MM investment this year. Maeda can’t be sent to the minors, so if he doesn’t win a rotation spot, he’ll either head back to long relief or be a release candidate.

Brant Hurter

A seventh-round pick in 2021, Hurter made his MLB debut last August. The 6’6″ lefty came out of the bullpen for all but one of his 10 appearances. He averaged 4.5 innings per appearance, though, so he was more or less operating as a bulk arm who generally followed an opener. Hurter had a strong debut, pitching to a 2.58 earned run average through 45 1/3 frames. He struck out 21.7% of batters faced against a 3.4% walk rate while getting grounders at an excellent 53.1% clip.

Hurter leans most heavily on a sinker that sits in the 92 MPH range. That pitch gets a lot of grounders but rarely misses bats. He showed more swing-and-miss potential with a low-80s breaking ball. Hurter recorded a lot of strikeouts up through Double-A. Hitters started putting the ball in play much more frequently at the top minor league level. There’s volatility with that approach, which is demonstrated by the 5.80 ERA which Hurter posted across 19 Triple-A appearances (18 starts). The Tigers could have some questions about how his arsenal would play against right-handed hitters, in particular, if he works as a traditional starter.

Keider Montero

Detroit added Montero to their 40-man roster during the 2023-24 offseason. They called him up for the first time late last May. The 24-year-old righty took the ball 19 times (including 16 starts) and worked 98 1/3 innings of 4.76 ERA ball as a rookie. The underlying marks weren’t great. His 18.7% strikeout rate and 9.4% swinging strike percentage were each a few points below average. He surrendered more than 1.7 home runs per nine innings. Montero’s 7.5% walk rate was fine and his fastball sat in the 94-95 MPH range, but his rookie year was mostly a struggle.

Montero has missed more bats in his minor league career, albeit with shakier control than he showed in his MLB action. He struck out 24.1% of opponents across 13 Triple-A starts. A walk rate north of 13% contributed to an unimpressive 5.03 ERA over 48 1/3 frames. Montero still has two option years and can bounce between Detroit and Toledo. While he has been a starter throughout his professional career, perhaps there’d be some intrigue in seeing how his stuff plays in a relief role.

Matt Manning

Manning, 27, is another former top 10 pick and top prospect in this mix. The 6’6″ righty has made 50 career starts over the past four seasons. He carries a 4.43 ERA across 254 innings. As with Mize, he has shown decent control but struggled to miss bats (16.4% strikeout rate). Manning fell fairly far down the depth chart last season. He only made five major league appearances while taking the ball 15 times for Toledo. He posted a 4.28 ERA while striking out a quarter of batters faced over 69 1/3 minor league innings. He battled a lat injury in the second half and was sidelined from around the All-Star Break until the middle of September.

This will be Manning’s final option year if he spends at least 20 days in the minors. He’s on track to qualify for arbitration next winter. It’s approaching make-or-break territory if he’s going to carve out a significant role in Detroit.

Ty Madden

Madden reached the majors for the first time last August. The Texas product had a limited role as a rookie. He pitched to a 4.30 earned run average with a 16.8% strikeout rate across 23 innings. Madden missed a lot more bats in the minors, where he punched out 28.3% of opposing hitters over 22 starts. That was about the only positive from his minor league numbers, though. Madden allowed nearly seven earned runs per nine. He gave up way too many home runs and walked nearly 10% of batters faced.

Baseball America ranked Madden as the #18 prospect in the Detroit system this winter. The outlet writes that his four-pitch mix and command are fringy. The stuff has been good enough to get whiffs against minor league hitters, but he’s probably ticketed for Triple-A to begin the season.

Tigers Decline Option On Casey Mize, Retain Club Control Via Arbitration

By | at

The Tigers declined their $3.1MM option on Casey Mize. That’s a procedural transaction, as Mize does not have the requisite six years of service to become a free agent. He remains under arbitration control and is projected by MLBTR contributor Matt Swartz for a $2MM salary. Detroit also outrighted Bligh Madris, Ryan Vilade and Bryan Sammons off the 40-man roster.

Mize took the ball 22 times this past season. The former first overall pick still hasn’t developed as hoped. He turned in a 4.49 ERA with a middling 17.3% strikeout rate. That limited his earning potential in arbitration. The modest $2MM projection means the Tigers will very likely bring Mize back to compete for a spot at the back of the rotation. He’ll be eligible for arbitration one more time before reaching free agency in the 2026-27 offseason.

Madris, Vilade and Sammons all played small roles for the Tigers in 2024. Madris and Vilade made a handful of appearances off the bench. Sammons, a rookie left-hander, pitched 27 1/3 innings of 3.62 ERA ball as a bulk pitcher. All three players can become minor league free agents.

Division Series Roster Notes: Padres, Dodgers, Phillies, Yankees, Tigers

By | at

We’ve already covered some notable roster additions for the Guardians and Mets as the Division Series begins, and the Royals are sticking with the same 26 players used in the Wild Card Series against the Orioles.  Now that all eight teams in the LDS rounds have revealed their rosters, here are the details…

  • The Padres made two changes from their NLDS roster, adding left-hander Martin Perez and right-hander Alek Jacob and removing Joe Musgrove and infielder Nick Ahmed.  Musgrove was obviously out due to his impending Tommy John surgery, while replacing Ahmed with a pitcher gives San Diego 13 pitchers to go with 13 position players.  Perez is one of five southpaws on San Diego’s roster, as ESPN’s Alden Gonzalez (X link) was among those who noted that the Padres are guarding themselves as best they can against Shohei Ohtani and other powerful left-handed Dodgers bats.
  • The Dodgers will go with an even mix of 13 batters and 13 pitchers, and rookie Edgardo Henriquez has made the list of available arms.  Henriquez only made his MLB debut on September 24 and he has played in just three games as a big leaguer, but Los Angeles will give the hard-throwing righty a look in October to add some velocity to the bullpen.  It’s probably safe to assume that Henriquez wouldn’t have made the cut if the Dodgers weren’t ravaged by pitching injuries, yet the rookie also got the nod over veteran Joe Kelly, who had an inconsistent year but was pitching well after returning from the IL in mid-September.  On the position player side, L.A. didn’t include either Kevin Kiermaier or James Outman, so Andy Pages will be the only true backup outfielder along with utilitymen Enrique Hernandez and Chris Taylor in the bench mix.
  • The Phillies will use 14 position players and 12 pitchers in their NLDS matchup with the Mets, with left-hander Kolby Allard joining the relief corps.  Allard has worked as something of a swingman throughout his career, and this ability of covering multiple innings earned Allard the spot, as manager Rob Thomson told MLB.com’s Paul Casella and other reporters.  “He’s going to probably give us the most length if we get into an extra-inning game….so I just wanted as much length as we could get,” Thomson said.  Utilityman Weston Wilson also got the Phils’ last bench spot, as Casella observes that Wilson brings more positional versatility than outfielder Cal Stevenson.
  • The Yankees went heavier on position players (15) than pitchers (11) for their ALDS roster against the Royals.  Anthony Rizzo is missing the series due to two broken fingers and DJ LeMahieu wasn’t yet activated from the injured list, but New York still has plenty of room on its bench, including pinch-running specialist Duke Ellis.  The Yankees appear to be loading up on bats to take on the Royals’ tough rotation and more porous bullpen, which left right-hander Marcus Stroman off the ALDS roster as the odd man out of the starting staff.
  • The Tigers made just one change from their Wild Card Series roster, as rookie righty Keider Montero has been included in place of Casey Mize.  Montero posted a 4.76 ERA over 98 1/3 innings in his first Major League season, starting 16 of 19 games.  This doesn’t necessarily mean Montero will start against the Guardians in the ALDS, however, as Detroit’s pitching staff (apart from ace Tarik Skubal) is very malleable in terms of specific roles.

Tigers Designate Joey Wentz For Assignment

By | at

2:55pm: The Tigers made these moves official and also announced that right-hander Alex Faedo was transferred to the 60-day IL. He landed on the 15-day IL on August 22 due to a right shoulder strain and the club announced that his season is over, per Cody Stavenhagen of The Athletic on X. Detroit’s 40-man roster count drops to 39.

2:03pm: The Tigers have designated left-hander Joey Wentz for assignment, reports Evan Petzold of the Detroit Free Press. He’ll be the corresponding roster move for right-hander Casey Mize, who is being reinstated from the 60-day injured list.

Wentz, 26, was the No. 40 overall pick by the Braves back in 2016. The southpaw quickly became one of the more prominent pitching prospects in what was then a stacked Braves farm system and made his way to the Tigers alongside outfielder Travis Demeritte in the trade that sent righty Shane Greene to Atlanta. Wentz made his big league debut with the 2022 Tigers and has pitched for Detroit in each of the past three seasons.

That 2022 cup of coffee proved to be a solid debut effort. Wentz started seven games, totaled 32 2/3 innings and posted a 3.03 earned run average along the way. His 20% strikeout rate and 9.6% walk rate didn’t necessarily stand out, but for a 24-year-old making his debut after just 12 appearances at the Triple-A level, it was an encouraging start all the same.

Unfortunately, that’s the most success Wentz has enjoyed in the majors to date. He appeared in 25 games with the 2023 Tigers — 19 of them starts — and was rocked for a 6.90 ERA with nearly identical strikeout and walk rates to that ’22 debut. Wentz became extremely homer-prone, however, surrendering an average of 2.13 round-trippers per nine innings pitched — the third-worst mark of any pitcher who totaled at least 100 innings last year.

Wentz’s 2024 season has been somewhat better but not enough to save his roster spot. In 55 1/3 innings, he’s pitched to a 5.37 ERA with a career-high 23.6% strikeout rate but also a career-worst 10.6% walk rate. He’s out of minor league options, so the Tigers couldn’t simply send him to Triple-A if they wanted to free up his roster spot. The DFA became a necessity in that regard, and Wentz will now be made available to all 29 other clubs via waivers.

If another club claims him, he’ll need to go right onto the big league roster, as he can’t be sent to the minors without clearing waivers. If he goes unclaimed, he lacks the service time and prior outright needed to reject a minor league assignment. As such, he’d stick with the Tigers as a depth option in Triple-A Toledo without occupying a 40-man roster spot.

Tigers Notes: Carpenter, Mize, Maeda

By | at

A pair of injured Tigers faced off in live batting practice yesterday, highlighting their progress towards returning to action. Outfielder Kerry Carpenter and right-hander Casey Mize both looked good during the session, which included a long home run and a single off Mize by Carpenter.

Carpenter, 27 in September, has been on the IL since May due to a lumbar spine stress fracture. He was in the midst of an incredible season when he hit the shelf, slashing a fantastic .283/.347/.572 with 10 doubles, four triples, and eight home runs in just 50 games. That performance was good enough for an excellent wRC+ of 149, and Carpenter’s return from the shelf should provide a big boost to the Tigers lineup down the stretch even as they’ve largely fallen out of playoff contention at this point. That return could be just over the horizon, as Carpenter told reporters (including Chris McCoskey of The Detroit News) yesterday that he’ll “probably” be starting a rehab assignment sometime this week. With both Carpenter and Riley Greene on the IL at the moment, the Tigers are currently relying on an outfield of Matt Vierling, Wenceel Perez, and Parker Meadows.

Despite the damage dealt by Carpenter, Mize also reportedly looked good during his two innings of work yesterday. As noted by MLB.com’s Injury Tracker, Greene (who also faced Mize yesterday) told reporters that the right-hander looked good and threw all of his pitches with confidence during the outing. Mize, who has been on the shelf for just over a month now due a hamstring strain, won’t be eligible to return from the 60-day IL until August 31 but could begin a rehab assignment of his own at some point in the near future as he builds back up towards MLB action. Mize’s 16 starts this year have been something of a mixed bag with a league average 4.23 ERA but a much stronger 3.69 FIP in 78 2/3 innings of work, though getting on the field at all was a meaningful step for the first overall pick of the 2018 draft after he made just two starts in 2022 and missed the whole 2023 campaign due to Tommy John surgery.

Mize’s eventual return to the rotation for the Tigers is sure to be a welcome one given the relatively dire situation the club’s starting staff has found itself in recently. After the club dealt Jack Flaherty to the Dodgers at the deadline and saw Reese Olson join Mize on the shelf due to shoulder strain late last month, the club is facing plenty of uncertainty behind ace Tarik Skubal. Rookies Bryan Sammons and Keider Montero have struggled to ERAs north of 5.00 and 6.00 respectively as fill-in starters this year while veteran righty Kenta Maeda had a 7.26 ERA in 16 starts before being moved to the bullpen just before the All-Star break.

Maeda has pitched somewhat better since moving to the bullpen, with a 4.40 ERA and a stronger 4.14 FIP in 14 1/3 innings of work across four appearances. As noted by Evan Petzold of the Detroit Free Press, manager A.J. Hinch recently told reporters that while the club expects the veteran to rejoin the rotation proper at some point, their current plan is to keep him in the bullpen for the time being while trying to get him “regular work that’s similar to a starting pitcher.” So far, that’s seemed to mean using Maeda as a bulk arm following an opener while mostly keeping him on a starting pitcher’s schedule. The Tigers are surely hoping that the 36-year-old can get right in the final months of the 2024 season as they look ahead to the final year of his two-year, $24MM contract in 2025.

Tigers Recall Dillon Dingler, Select Bryan Sammons

By | at

The Tigers announced a series of roster moves today, recalling catcher Dillon Dingler and infielder Ryan Kreidler. They also selected the contract of left-hander Bryan Sammons. One active roster spot was opened by last night’s Carson Kelly trade. The Tigers opened two more spots by optioning left-hander Easton Lucas and placing shortstop Javier Báez on the medical emergency/bereavement list. To open a 40-man spot for Sammons, right-hander Casey Mize was transferred to the 60-day injured list. Evan Petzold of the Detroit Free Press reported last night that Dingler would be coming up to the majors for the first time.

Dingler, 25, was a second-round pick of the Tigers in 2020 and has been considered one of their top prospects since then. His defense behind the plate is considered strong but there’s more uncertainty with his offense, as he can hit for power but also strikes out a lot.

He has stepped to the plate just under 1500 times in his minor league career thus far, getting punched out in 27.5% of those. But he’s also displayed that power with 59 home runs. Overall, he’s hit .257/.344/.459 for a wRC+ of 114.

It appears he has made notable strides in the strikeout department this year, as he has only been punched out in 20.3% of his 301 Triple-A plate appearances. But he’s still hit 17 home runs and drawn walks at a 10% clip. All that leads to a .308/.379/.559 batting line and 137 wRC+. With Kelly now out of the picture, Dingler figures to get a decent amount of playing time, sharing the catching duties with Jake Rogers.

Sammons, 29, gets the call for the first time as well. He was drafted by the Twins back in 2017 and has never really been a top prospect. But he has been starting in the minors and might be needed to soak up some innings. Jack Flaherty was supposed to start tonight but was scratched as he’s likely to be traded at any moment. Beau Brieske is starting tonight in what is likely to be a bullpen game.

That could leave Sammons taking on some bulk innings. He has made 17 Triple-A starts this year with 84 innings pitched. In that time, he has a 4.18 ERA, 21.8% strikeout rate, 9.5% walk rate and 36.4% ground ball rate.

As for Mize, he landed on the IL July 3 due to a left hamstring strain. He’ll now be ineligible to return until 60 days from that point, which would be early September. Manager A.J. Hinch said it would be a “photo finish” to get back by that time, per Cody Stavenhagen of The Athletic on X, so he might be able to return when first eligible.

Tigers Skipping Jack Flaherty’s Start Due To Back Discomfort

By | at

The Tigers scratched Jack Flaherty from tomorrow’s scheduled start against the Twins. The right-hander remained in Los Angeles after his start against the Angels last Thursday to receive an injection to treat back soreness, writes Chris McCosky of the Detroit News.

For the moment, it doesn’t seem the situation is concerning. Manager A.J. Hinch told the Detroit beat on Tuesday afternoon that the team remains confident he’ll avoid the injured list (relayed on X by Cody Stavenhagen of the Athletic). McCosky reports that the Tigers are targeting next week’s home series against the Guardians for Flaherty to take the ball.

A team skipping a pitcher’s start to treat a minor back issue wouldn’t ordinarily be noteworthy. Yet Flaherty’s health is of utmost importance with less than a month before the trade deadline. Detroit lost on Tuesday to fall nine games below .500. They’re all but assured of going into deadline season as at least soft sellers. It stands to reason they’ll be reluctant to move players whom they have under control for multiple years. They should deal their most appealing impending free agents. Flaherty tops the list.

Detroit’s decision to sign Flaherty to a one-year, $14MM pillow contract was one of the best moves of the 2023-24 offseason. Despite a rocky outing in his most recent appearance, he carries a 3.24 ERA over 15 starts. Flaherty has punched out 33% of batters faced behind an excellent 14.2% swinging strike rate. He has walked a career-low 4% of opposing hitters. He should get his first All-Star nod this summer.

Assuming he’s healthy, Flaherty figures to find himself in plenty of trade rumors coming out of the Midsummer Classic. He’ll almost certainly be the best rental starting pitcher on the market. MLBTR slotted Flaherty as the #3 pitcher on our ranking of the upcoming free agent class last week. The players above him, Corbin Burnes and Max Fried, aren’t getting traded.

Beyond Flaherty, the rental rotation market could include the likes of Yusei Kikuchi, Michael Lorenzen, Jose Quintana and Frankie Montas. As the best impending free agent starter available, Flaherty could net the Tigers a prospect package headlined by a borderline Top 100 caliber talent. If they don’t trade him, Detroit could make him a qualifying offer at the end of the season. Assuming Flaherty signed elsewhere for at least $50MM, the Tigers would get a pick after the first round in the 2025 draft. Detroit should nevertheless find a prospect package within the next few weeks that they consider more valuable than the draft choice.

Keider Montero will get the ball tomorrow in Flaherty’s absence. As first reported by Jason Beck of MLB.com (on X), Detroit is recalling the rookie righty less than a week after optioning him. That’s only permissible if Montero is replacing a player on the roster who is headed to the injured list. That won’t be Flaherty but right-hander Casey Mize, who is ticketed for the 15-day IL after suffering a left hamstring strain in his start on Sunday. The former first overall pick owns a 4.23 ERA despite a modest 16.8% strikeout rate over 16 starts in his return from Tommy John surgery.

Casey Mize, Reese Olson Win Rotation Spots With Tigers; Matt Manning Optioned To Triple-A

By | at

The Tigers announced Friday that they’ve optioned right-hander Matt Manning to Triple-A Toledo. That puts an end to the three-horse race for the final two spots in manager AJ Hinch’s rotation. Right-handers Casey Mize and Reese Olson will open the season on the starting staff behind lefty Tarik Skubal and righties Kenta Maeda and Jack Flaherty. Detroit also reassigned non-roster right-hander Drew Anderson to minor league camp.

Detroit’s talented trio of right-handers didn’t make the decision easy — at least not in terms of spring results. Each of Mize, Olson and Manning pitched between 14 2/3 innings and 16 innings this spring, and none posted an ERA north of Olson’s 3.68. Olson posted the best blend of strikeout and walk rates in camp (22.6% and 6.5%, respectively). Mize notched the lowest ERA but the highest walk rate. Manning was perhaps done in by the six home runs he yielded in 16 innings.

While Manning won’t open the season in the rotation, it’s likely that he, Mize and Olson will all make their share of starts in Detroit this season. Mize is in his first full season back from Tommy John surgery and back surgery. He’ll be on an innings limit of some degree. Injuries in the rotation are also a virtual inevitability. Even with Manning opening the year in Toledo, it wouldn’t be a shock to see him start 15-plus games in the bigs.

Mize, 27 in May, was the No. 1 overall pick in the 2018 draft. He showed plenty of promise in 2021, tossing 150 1/3 innings of 3.71 ERA ball with a below-average 19.3% strikeout rate but a strong 6.7% walk rate and similarly encouraging 48.1% ground-ball rate. That looked to set the stage for Mize to seize a long-term spot in the Detroit rotation, but he unfortunately suffered a UCL tear early in the 2022 season. He wound up undergoing Tommy John surgery and, while he was rehabbing that procedure, underwent surgery to address a nagging back issue that had been plaguing him for some time. He’s still under club control for three seasons.

Olson, 24, made his big league debut with Detroit last season and quickly impressed. In his first 103 2/3 MLB frames, he turned in a 3.99 ERA with average or better strikeout (24.4%), walk (7.8%) and ground-ball (42.8%) rates. Olson supported those rates with solid marks in swinging-strike and opponents’ chase rates as well. The Tigers control him all the way through 2029.

The 26-year-old Manning was Detroit’s first-round pick back in 2016. He’s pitched in parts of three big league seasons, logging a 4.37 ERA with a 16.1% strikeout rate, 7.8% walk rate and 41.6% grounder rate. Manning hasn’t missed bats at the levels expected throughout his time as a top-ranked prospect, but he’s shown solid command and kept the ball in the yard nicely to this point in his career. He’s also had frequent bad luck with injuries, including a 2023 season in which he incredibly broke his foot on two separate occasions upon being struck by a comeback line-drive. He’s under club control through 2027 and will remain a notable piece of the Tigers’ rotation puzzle in the foreseeable future, even if he starts this season out in Toledo.
