Less than 12 hours after the Cardinals needed 12 innings from the bullpen in a 3-2 loss in 19 innings of a game that ended in the wee hours Wednesday, Wacha had some difficulty loosening his right shoulder during warmups for the game that afternoon. He notified coaches, attempted to free the shoulder while pitching the first inning and eventually had to surrender to tightness in the second inning. He abruptly left the game for an uncertain future.
Wacha is scheduled to have a magnetic resonance imaging scan taken of his right shoulder Thursday to determine the specific injury, and its severity.
