Orioles rookie first baseman Ryan Mountcastle exited in the third inning of Friday’s game against the Tampa Bay Rays two innings after being tagged in the head on a stolen base attempt, with the team saying he left to be evaluated per concussion protocols.
Mountcastle plated the first run of Friday’s game at Camden Yards with a two-out RBI single in the bottom of the first. When he then attempted to steal second base, Tampa Bay shortstop Wander Franco’s tag got him in the helmet. Mountcastle lay on the ground grimacing before getting up and taking over at first base in the top of the second.
