MLB Source: Initial diagnosis for #Astros closer Roberto Osuna is that he needs to undergo season-ending Tommy John surgery. However, Osuna is getting a second opinion. If the initial diagnosis is accurate it would be huge loss for the Astros.

Manager Dusty Baker did not confirm that diagnosis, but signaled pessimism on Osuna’s long-term outlook.
Houston #Astros closer Roberto Osuna is being evaluated today by specialists for his ailing right elbow, but manager Dusty Baker says, "it's not looking real good.''

Tommy John surgery would certainly end Osuna’s 2020 season, and would sideline him for a large portion of 2021 as well. He had appeared in four games this season, posting a 2.08 ERA.
The Astros have already lost ace Justin Verlander for an extended period of time. Losing both pitchers for much of the season would be a huge blow to their championship hopes.
