12:59pm: The initial diagnosis is that Osuna requires Tommy John surgery, Mark Berman of FOX 26 reports on Twitter. He’ll go for a second opinion.
If indeed that major reconstruction is required, it could have major ramifications beyond the present season. Osuna is earning $10MM this year (on a full-season basis) and would be due a raise through arbitration for 2021. It’s quite possible that he’d miss all or virtually all of the ensuing season if he requires a UCL reconstruction, so the ’Stros may end up cutting him loose at the end of the season.
12:44pm: The Astros had been hoping for good news after closer Roberto Osuna came down with an elbow injury. Astros manager Dusty Baker indicated in an appearance on SportsTalk 790 that the club is now bracing for the worst (link to audio stream).
“Doesn’t look real good, actually,” Baker explained. “[Osuna] went and had an MRI yesterday. He’s in our prayers and in our thoughts. The reality is it’s probably not really good news.”
Whether Baker knows of an initial diagnosis isn’t evident, but it seems clear the organization anticipates a lengthy absence. Given the short schedule, there wouldn’t be much time for Osuna to work back from a significant injury — let alone to recover from a major surgery.
