The Orioles will be without first baseman Ryan Mountcastle for 8-12 weeks after imaging revealed a Grade 2 strain of his right hamstring, interim manager Tony Mansolino told reporters (including MLB.com’s Jake Rill). Baltimore placed him on the 10-day injured list and recalled Coby Mayo last week. Mountcastle’s injury is significant enough that he’ll eventually be moved to the 60-day IL when the team needs to create a 40-man roster spot.
A Grade 2 strain is viewed of “moderate” severity and involves a partial muscle tear. It’s the biggest blow in what has been a frustrating season for the 28-year-old infielder. Mountcastle has hit .246/.280/.348 with only two home runs across 200 plate appearances. Those would be career-worst numbers across the board. Mountcastle has been a slightly better than average hitter for most of his five-year MLB career. Last season’s .271/.308/.425 showing is more representative of his overall body of work.
This very likely takes him off the board as a trade candidate. Even a return at the short end of the timeline would be after the July 31 deadline. Injured players can be traded, but Baltimore would be hard-pressed to find interest between the rough first couple months and the extended absence. Mountcastle is playing on a $6.787MM salary and will surpass the five-year service threshold. He’ll be eligible for arbitration once more next winter, but a projected $7MM+ sum figures to make him a non-tender candidate. That’d be particularly true if the recovery carries towards the back end of the timeline and keeps him out into September.
Ryan O’Hearn has outperformed Mountcastle this season and had already taken the first base job. Mayo has been playing regularly between first base and designated hitter for the past week. The O’s activated Ramón Laureano from the injured list this afternoon. He’s in tonight at DH against A’s lefty JP Sears. Baltimore should also welcome Jordan Westburg and Gary Sánchez back relatively soon. Both players are on rehab stints at Triple-A Norfolk.
