The Tigers already knew Bailey Horn wasn't pitching his way back into the bullpen anytime soon. Now it's official: the lefty reliever went under the knife for Tommy John surgery, closing the book on a 2026 season that never really got off the ground and pushing his return deep into 2027.

This one's been a slow burn. Horn had an arthroscopic procedure on his left elbow before the season even started and landed on the 60-day injured list back on April 22. He tried to build up his arm in early April, but the soreness never really went away. A hydrodissection procedure in June was supposed to be the fix that kept him off the operating table. It wasn't. Doctors ultimately found a torn ligament, and reconstructive surgery became the only real option.
It's a rough outcome for a guy who looked like a real weapon out of the Tigers pen when healthy. Horn threw just 11.1 innings for Detroit in 2025 but was dominant in that small sample, posting a 1.59 ERA with 10 strikeouts across 10 appearances. That kind of stuff is exactly why losing him for the long haul stings — the Tigers didn't even get a full look at what he could do in a real workload before the elbow shut him down for good.

Tommy John recoveries typically run 12 to 14 months, sometimes longer for pitchers who need extra time to rebuild arm strength and command. That timeline puts Horn on track to miss the rest of 2026 outright and likely a chunk of 2027 too — best case, he's fighting for a bullpen spot again next summer. For a Tigers relief corps that's leaned on cheap, high-upside arms the last couple years, losing a sub-2.00 ERA lefty for that long isn't nothing.
For now it's another name on the ever-growing pile of 2026 Tommy John casualties, and another reminder of how fragile reliever arms are even when the underlying stuff is nasty. The Tigers will lean on the rest of their bullpen depth to cover the innings Horn was supposed to eat, and all anyone can do is circle 2027 and hope the elbow holds up the second time around.
