Brandon Walter: Everything you need to know

The Astros placed Walter (elbow) on the 60-day injured list. Putting Walter on the 60-day IL gives Houston another 40-man roster spot to play with. The lefty will miss the entire 2026 campaign after having Tommy John surgery last September.

Walter (elbow) was activated from the 60-day injured list Thursday, Brian McTaggart of MLB.com reports. This move is procedural as the Astros set their 40-man roster for the offseason. Walter is recovering from Tommy John surgery and will miss the entire 2026 season.

Walter (elbow) underwent Tommy John surgery Monday, Chandler Rome of The Athletic reports. The Astros announced that Walter was slated for elbow surgery a couple of weeks ago, but now that we know he specifically underwent a Tommy John procedure, it's safe to assume the left-hander won't return to a big-league mound until 2027. It's a notable loss for the Astros' rotation, as Walter finished his first season in Houston with a 3.35 ERA and 0.93 WHIP through 53.2 innings spanning nine starts.
