2:14pm: The Astros have placed Osuna on the 10-day injured list with right elbow soreness, according to Chandler Rome of the Houston Chronicle. He’ll be replaced on the active roster by right-handed pitcher Humberto Castellanos, who had previously been on the Astros’ taxi squad.
8:46am: Astros closer Roberto Osuna left Saturday’s game due to an arm injury, and manager Dusty Baker told reporters that Osuna will head from Anaheim to Houston to undergo an MRI. Facing his third batter of the ninth inning last evening, Osuna threw a pitch to the Angels’ Jason Castro and immediately signaled for the trainer to visit the mound. The right-hander was removed and replaced with Cy Sneed.
In the short term, Osuna’s injury quite possibly cost Houston the game, as Castro hit an RBI double to tie the score, and the Angels then scored the winning run in the 10th. But Saturday’s defeat could be a relatively small matter compared to a potentially serious arm problem for Osuna, especially considering how the Astros’ pitching staff has already been ravaged by injuries.
Chris Devenski, Brad Peacock, Joe Biagini, Jose Urquidy, Austin Pruitt, and reigning AL Cy Young Award winner Justin Verlander are all on the injured list, while Ryan Pressly only just returned from a sore elbow. The Astros have made some recent acquisitions (signing Fernando Rodney and acquiring Hector Velazquez from the Orioles) to help fill out their pitching depth, though there’s only so much that can be done to replace so many sidelined hurlers.
Should Osuna’s MRI reveal any bad news, his loss would be a particularly tough one for the Astros. Osuna has a 2.45 ERA, 6.33 K/BB rate, and 9.3 K/9 over 92 innings since coming to the Astros from the Blue Jays in July 2018. Pressly might be the top choice for save situations with Osuna sidelined, though the club might want to ease Pressly back in action considering that Saturday marked his first game of the season.
