EDGE Analysis

Mountcastle led off the bottom of the ninth inning with a single, but he was visited by a trainer and left the game after reaching first base. Prior to his departure, he went 2-for-4 with a solo homer, two runs, a walk and a strikeout. The nature of his injury isn't yet known, and it's not clear whether he'll be available for Monday's series opener against the Yankees.
