Orioles' Ryan Mountcastle: Back in action Monday

Mountcastle (triceps) is batting third as the designated hitter Monday versus the Tigers, Rich Dubroff of BaltimoreBaseball.com reports.

Mountcastle appears to have recovered from the tricep contusion, which he suffered on a hit-by-pitch in Saturday's game. He figures to share playing time at first base and designated hitter with Jesus Aguilar going forward.
