RHP Stolmy Pimentel pitched one scoreless inning of relief Tuesday night on his rehab assignment for Double-A Altoona against Richmond in an Eastern League game, though he allowed two hits and a walk.

CF Andrew McCutchen was removed from the 5-2 win over St. Louis on Tuesday night after five innings because of discomfort in his left ribcage. McCutchen was on the disabled list from Aug. 4-18 with a stress fracture in his lower left ribcage. However, he said he left the game for precautionary reasons and should be able to play Wednesday.

1B Pedro Alvarez left the game after the sixth inning with a sprained left foot. It was not clear exactly how Alvarez was injured and it seems doubtful he will be able to play Wednesday. Though he was able to walk out of the clubhouse, he was unable to wear a shoe on the foot.
