Jack Flaherty Expected to Miss More than 15 Days with Current Flexor Strain

Detroit Tigers manager A.J. Hinch said he expects starting pitcher Jack Flaherty (forearm) to miss "more than the minimum" 15 days with his current forearm injury, per Cody Stavenhagen of The Athletic. Flaherty was placed on the 15-day injured list on July 21 due to right flexor inflammation. The veteran right-hander has yet to resume throwing, and it appears he could be facing an extended absence. Across 86 1/3 innings (19 starts) before the injury, Flaherty recorded a 3-8 record with a 4.59 ERA, 1.41 WHIP, and 102 strikeouts. The 30-year-old has maintained a strong 26.2% strikeout rate this season, but he's walked 10.8% of the batters he's faced and has allowed a 46.2% hard-hit rate. With Flaherty sidelined, Tigers right-hander Keider Montero has rejoined the team's starting rotation.

Jack Flaherty Placed on 15-Day Injured List with Right Flexor Inflammation

Detroit Tigers starting pitcher Jack Flaherty (forearm) was placed on the 15-day injured list on Tuesday due to a right flexor strain, per a team announcement. It's the second trip to the IL this season for Flaherty, who missed time in June with a lower leg injury. While the full extent of Flaherty's current health situation is not yet known, any forearm injury is a worrying sign for a pitcher. Across 86 1/3 innings (19 starts) in 2026, Flaherty has recorded a 3-8 record with a 4.59 ERA, 1.41 WHIP, and 102 strikeouts. The 30-year-old owns an impressive 26.2% strikeout rate, but he's also walked batters at a 10.8% clip. As the corresponding move to Flaherty's placement on the injured list, Detroit recalled right-hander Ty Madden.

Jack Flaherty to Officially Return on Sunday Against Astros

Detroit Tigers right-hander Jack Flaherty (ankle) will officially come off the 15-day injured list to start on Sunday in the series finale against the Houston Astros at Comerica Park, manager A.J. Hinch told Jared Ramsey of the Detroit Free Press. Flaherty has been sidelined since June 13 with an injury to a tendon in his ankle. The 30-year-old veteran has had a frustrating season to this point, leading the league with eight losses while posting a 5.35 ERA (4.09 FIP) and 1.57 WHIP with 78 strikeouts and 34 walks in 65 2/3 innings pitched over his 15 starts in his second year in Detroit. Flaherty sits in just the fourth percentile in hard-hit rate this year, but he's in the 73rd percentile in strikeout rate and didn't allow more than three earned runs in any of his last five starts before going on the IL with his ankle injury. His xERA (4.64) and xwOBA (.334) suggest he's had some bad luck in the first half as well, so Flaherty shouldn't just be blindly avoided in fantasy leagues because of his eight losses and ERA over 5.00.

Jack Flaherty on Track to Return on Sunday Against Astros

Nothing is official yet, but Detroit Tigers right-hander Jack Flaherty (ankle) is on track to be activated from the 15-day injured list to start against the Houston Astros on Sunday, according to Chris McCosky of The Detroit News. The Tigers might roll with six starting pitchers for at least one turn through the rotation. The Tigers saw enough after Flaherty allowed two runs in 5 2/3 innings while striking out seven in his minor-league rehab start on Tuesday at Double-A Erie. He threw 83 pitches in that outing, so he shouldn't be facing any workload restrictions in his likely return to Detroit's rotation this weekend against Houston. The 30-year-old's scheduled matchup on Sunday isn't a bad one, but fantasy managers in deeper leagues aren't in any hurry to throw Flaherty back into their starting lineups after he went 1-8 with a 5.35 ERA ( 4.09 FIP) and 1.57 WHIP with 78 strikeouts and 34 walks in 65 2/3 innings across his first 15 starts in 2026. But if Flaherty can get his walk rate down going into the second half of the year, he could be a positive regression candidate to target on the waiver wire. Flaherty is currently rostered in 42% of Yahoo leagues.

Jack Flaherty Fans Seven in Minor-League Rehab Game

Detroit Tigers right-hander Jack Flaherty (ankle) looked good in his minor-league rehab start on Tuesday at Double-A Erie, allowing two earned runs on three hits while walking just one and striking out seven in 5 2/3 innings of work, according to Chris McCosky of The Detroit News. Flaherty threw 58 of his 83 pitches for strikes in his first rehab start since landing on the 15-day injured list with a left-ankle injury. All signs are pointing to the veteran right-hander coming off the IL when he's eligible to be reinstated on June 28, barring a setback during a between-starts bullpen session. Fantasy managers won't be in any hurry to add the 30-year-old former 34th overall pick by the St. Louis Cardinals in 2014 when he's ready to return, as he went on the IL with a 1-8 record, 5.35 ERA, and 1.57 WHIP with 78 strikeouts and 34 walks in 65 2/3 innings over his first 15 starts in 2026 in his second year in Motown. Flaherty's 11.1% walk rate isn't ideal, but he also doesn't have a terrible 25.5% strikeout rate, and the underlying metrics suggest he has been a bit unlucky in the first half so far. He's currently rostered in under half of Yahoo leagues.

Jack Flaherty to Make a Rehab Start on Tuesday

Detroit Tigers right-hander Jack Flaherty (ankle) will make a minor-league rehab start on Tuesday at Double-A Erie, according to Cody Stavenhagen of The Athletic. Reports coming out of Flaherty's bullpen session were all positive, so he could be cleared to return from the 15-day injured list after making only one rehab start in the minors. Fantasy managers probably are in no rush to pick the 30-year-old veteran starter back up off the waiver wire, though, after he went 1-8 with a 5.35 ERA (4.09 FIP) and 1.57 WHIP with 78 strikeouts and 34 walks in 65 2/3 innings pitched over his first 15 starts before injuring his ankle. The former first-round pick by the St. Louis Cardinals in 2014 allowed three runs or fewer in each of his last five starts, though. If Flaherty can improve his command in the second half of the year in Detroit -- he currently has an 11.1% walk rate -- positive regression should follow. While he's recovering from his ankle injury, Flaherty is rostered in 42% of Yahoo leagues.

Jack Flaherty to Throw a Bullpen on Saturday

Detroit Tigers right-hander Jack Flaherty (ankle) will throw a bullpen session on Saturday, according to Cody Stavenhagen of The Athletic. Flaherty will be throwing off a mound for the first time this weekend since a strained left peroneal muscle in his ankle landed him on the 15-day injured list last week. Barring a setback as he begins to ramp back up, Flaherty has a chance to return to the Tigers' starting rotation before the All-Star break in mid-July. He's eligible to come off the IL on June 28. The 30-year-old veteran is leading the league in losses (eight) in 2026 for the second straight season in Detroit and has a bloated 5.35 ERA (4.08 FIP) and 1.57 WHIP with 78 strikeouts and 34 walks in 65 2/3 innings across his 15 starts. Flaherty hasn't pitched as poorly as his underlying metrics suggest, but fantasy managers don't have a whole lot of incentive in shallow-mixed leagues to keep him stashed for the time being. He's currently rostered in only 43% of Yahoo leagues.

Tigers Place Jack Flaherty on Injured List With Peroneal Strain

The Detroit Tigers announced on Saturday that they placed right-hander Jack Flaherty (ankle, foot) on the 15-day injured list with a left peroneal strain and recalled infielder Hao-Yu Lee from Triple-A Toledo in a corresponding move. The Tigers pulled Flaherty from his start early on Friday against the Cleveland Guardians with an injury to his outer ankle/foot. The good news for Detroit is that they are getting ace left-hander Tarik Skubal (elbow) back on Saturday, with right-hander Casey Mize (groin) coming back from the IL on Sunday in the series finale against Cleveland. It's unclear how much time Flaherty will be forced to miss, but he will at least be out for a couple of turns through the starting rotation. The 30-year-old veteran has had a rough second year in Motown, losing a league-high eight games in his first 15 starts, also posting an ERA above 5.00 with a 1.57 WHIP, 78 strikeouts, and 34 walks in 65 2/3 innings pitched. Flaherty has been a bit unlucky this year, but even when considering his 4.60 expected ERA and 4.10 FIP, there's not a ton to like. He's currently rostered in just under half of Yahoo leagues.

Jack Flaherty Injures his Leg on Friday Against the Guardians

Detroit Tigers right-hander Jack Flaherty (leg) left his start early on Friday against the division-rival Cleveland Guardians due to left-leg discomfort, according to Cody Stavenhagen of The Athletic. Flaherty's tough 2026 season continued, as he not only departed early with an injury, but he also took his eighth loss of the year in a 3-2 defeat at the hands of Cleveland at Progressive Field. Before hitting the showers early on Friday night, Flaherty allowed two earned runs on three hits while walking one and striking out one in only three innings. It's unclear right now if his injury is serious enough to warrant a trip to the injured list. The good news for the Tigers is that they have both left-hander Tarik Skubal (elbow) and right-hander Casey Mize (groin) returning to their starting rotation this weekend on Saturday and Sunday, respectively. The 30-year-old Flaherty entered his start on Friday with an elevated 5.31 ERA (4.12 FIP) and 1.58 WHIP with 77 strikeouts and 33 walks in 62 2/3 innings over his 14 starts in his second year in Motown.

Jack Flaherty Punches Out 10, Takes Tough-Luck Loss to Red Sox

Detroit Tigers right-hander Jack Flaherty struck out a season-high 10 batters on Wednesday night against the visiting Boston Red Sox, but he was still handed his third loss of the season in the team's 4-0 shutout loss at Comerica Park. Flaherty went five innings, allowing four runs (two earned) on three hits while also walking just one. The 30-year-old veteran is winless on the campaign so far, but his outing on Wednesday evening was an encouraging one after he allowed 10 earned runs in 5 2/3 innings in his previous two starts versus the Cincinnati Reds and Texas Rangers. Flaherty now holds a 5.56 ERA (5.32 FIP) and 1.65 WHIP with 42 strikeouts and a league-high 26 walks in 34 innings pitched across his eight starts to begin the 2026 season. He also leads the league with five hit-by-pitches, so clearly, control has been an issue for Flaherty early on. He'll be in play as a streaming option for fantasy managers his next time out against the struggling New York Mets.
