Matt Adams smacked a walk-off two-run homer in the bottom of the ninth inning to lift the Cardinals past the Pirates 2-0 in the opener of a four-game series at Busch Stadium. Adam Wainwright pitched seven scoreless innings while Pat Neshek picked up the win. The Redbirds snapped a brief two-game skid. Starling Marte and Neil Walker had two hits apiece for Pittsburgh, which was coming off a weekend sweep of Philadelphia. Charlie Morton gave up just one hit and two walks over seven shutout innings but did not factor in the decision. Justin Wilson suffered his first loss.
