The Tigers’ bullpen picture took another hit Friday, and this one may linger well beyond this season.
Bailey Horn will have Tommy John surgery on his left arm and is done for the year, according to Chris McCosky of the Detroit News on X (formerly Twitter). With the calendar already in mid-July, and depending on the exact elbow procedure, Detroit may not see him back in a big league game until 2028.
Horn had already been working through a messy injury timeline. He underwent arthroscopic surgery on his left elbow before the season and had been on the 60-day injured list since April 22.
MLB.com reported that he also had a hydrodissection procedure in June to address lingering soreness. Now the next step is the game’s most familiar major surgery.
For Horn, the setback lands after a career that has bounced all over the map. The White Sox took him in the fifth round in 2020, and since then he’s moved through several organizations, including the Cubs, Red Sox and Tigers.
In fact, both the White Sox and Tigers have had him twice. He pitched in 18 games for Boston in 2024, then got into 10 games for Detroit in 2025 and made the most of it.
In those 11.1 innings with the Tigers, Horn went 0-1 with a 1.59 ERA, striking out 10 and walking seven. He didn’t appear in the postseason, but he gave Detroit a useful back-end option when the club needed one last year. The hope was that he’d build on that and maybe grow into a left-handed setup piece as the Tigers kept adding right-handed closers in free agency.
That path is off the table for now, and his future in Detroit is suddenly much murkier. The Tigers don’t need to make an immediate move because Horn is on the 60-day injured list and doesn’t count against the 40-man roster. Once the season ends, though, they’ll have to either protect him on the 40-man or designate him for assignment.
That leaves Detroit with a familiar roster gamble. The club would be hoping Horn clears waivers, allowing them to keep him in the organization and let him keep rehabbing in the minors. The appeal is obvious: he still has at least four years of team control left, and he showed enough last season to matter.
Horn’s injury is just the latest blow in a season that has been brutal on Tigers pitchers. Justin Verlander, who said before the All-Star break that he will retire after the season, remains on the injured list with left hip inflammation. Will Vest landed on the IL earlier this month with a right elbow stress fracture.
Brant Hurter and Burch Smith were both rehabbing in Florida during the All-Star break; Hurter is dealing with lumbar spine inflammation, while Smith has right shoulder inflammation.
Jackson Jobe, once one of the organization’s top prospects, is beginning his build-up from Tommy John surgery but likely needs another month before he can be considered an option. Reese Olson, like Horn, is finished for the season after right shoulder surgery.

Tigers Deadline Pressure Just Hit A Point Scott Harris Can't Ignore
The Tigers have spent much of the season trying to answer a simple question with a complicated roster: are they ready to act like a contender, or still stuck in the middle? Around the league, that uncertainty has turned Detroit into one of the more interesting clubs to watch as the deadline approaches, with Tarik Skubal at the center of the conversation and the bullpen still looking like the clearest area that needs help.
Scott Harris does not have much margin for another cautious pass this time, especially with relief options beginning to surface from teams that could be pushed into selling. Garrett Whitlock, Brooks Raley and Kirby Yates all bring different appeal depending on how their current clubs finish the month, and the Tigers will have to decide whether they want a cleaner short-term fix or a bigger swing that better matches where they think this team is headed.

Kenley Jansens Tigers Role Suddenly Feels Far Less Certain
The Tigers bullpen has been in motion for weeks, and the latest ripple has come from Keider Montero, whose ability to cover multiple innings has given AJ Hinch more ways to get through games without leaning as heavily on the veteran late-inning arms. That has changed the rhythm for both Kyle Finnegan and Kenley Jansen, two relievers who were expected to be central pieces but have found their usage trimmed as Detroit keeps adjusting to the shape of a long season.
Jansen has been part of those conversations with Hinch, and the broader message is clear: roles are still being sorted out as the Tigers juggle a busy schedule and a rotation that is about to shift again. Montero is also expected to factor into the starting mix soon, which means the bullpen picture could look different again before long, leaving Jansens place in it a little less settled than it seemed not long ago.
