Bad news for Astros pitching prospect Corbin Martin: he underwent Tommy John surgery on Wednesday. He’s out for this season and, in all likelihood, most of next year as well.

Martin, 23, was a top-10 prospect in the Astros system heading into this season. He was promoted to the bigs in mid-May to deal with some injuries in Houston’s big league rotation, made five pretty poor starts, and was sent back down. Once back in the minors he was shellacked and, eventually, shut down due to an obvious elbow injury. Surgery was recommended after he received a second opinion.

Martin’s loss doesn’t have a tremendous impact on the 2019 Astros, but it does put a dent in their pitching depth in the event they need to patch a hole and, obviously, is a major blow to Martin’s own development.
