The Astros are activating Hayden Wesneski off the 60-day injured list on Wednesday, ending a rehab road that started with Tommy John surgery back in May 2025. He'd made just 6 starts that season, running a 4.50 ERA across 32 innings, before his elbow gave out and the clock reset on his whole year.
MLB Trade Rumors confirmed the move Wednesday, capping Wesneski's long road back.
This isn't just a feel-good rehab story, it's a real roster need. Wesneski slots into Houston's rotation after Spencer Arrighetti went down with his own injury, joining Hunter Brown, Peter Lambert, Ronel Blanco and Tatsuya Imai as the Astros try to keep their arms afloat during the stretch run. That's the kind of domino effect that turns a bullpen depth piece into a stopgap starter overnight.
The buildup went about as well as it could have. Wesneski posted a 2.25 ERA with 21 strikeouts against just 4 walks over 20 minor league innings on his way back, and he capped it with a 4-1/3 scoreless-inning, 7-strikeout tune-up at Triple-A. That's not just clearing a rehab checklist, that's legitimately sharp stuff heading into a big league mound he hasn't stood on in over a year.
Houston is reportedly lining him up to start the series finale in Anaheim, and with roughly 80 pitches banked in his last outing, he should be good for 4-5 innings right out of the gate. For a team that's been piecing together a rotation on the fly, that's a real number, not just a symbolic first start.
The bigger picture here is about survival math. Every contender loses arms in July, and the ones who navigate it best are the ones with internal reinforcements ready to plug in. Wesneski, a 28-year-old who was a useful back-end piece for the Cubs and then Astros before the elbow blew out, is exactly that kind of reinforcement. Whether he can hold up over a full workload after 14 months off is the next question, but for now Houston will just take the arm.
