Orioles Announce Ryan Mountcastle Injury Update

The Baltimore Orioles are preparing to be without first baseman Ryan Mountcastle for the forseeable future.

Interim manager Tony Mansolino told reporters Wednesday that Mountcastle, who recently underwent an MRI on his right hamstring, will be sidelined "a while," per Roch Kubatko of MASNSports.com. While the team has not provided an official timetable, the phrasing suggests Mountcastle could be out indefinitely as he recovers from the strain.

Mountcastle was placed on the injured list earlier this week, prompting Baltimore to recall Coby Mayo from Triple-A Norfolk.

Mayo now appears to have a clear path to regular at-bats, either at first base or as the designated hitter. Ryan O'Hearn, who has split time between the outfield and first, is also expected to handle more duties at the cold corner while Mountcastle is sidelined.

The 27-year-old slugger has been a steady contributor in the heart of the Orioles lineup. Mountcastle is slashing .264/.319/.420 with 10 home runs and 34 RBIs across 58 games. His absence creates a void in both offensive production and experience, as the Orioles turn to younger options.

Mountcastle is the 12th player the Orioles currently have on the IL. Outfielder Cedric Mullins landed on IL just hours before Mountcastle exited with right hamstring discomfort.
