Cardinals starter Jack Flaherty picked up where Miles Mikolas left off, blanking the Pirates in the first four innings on Tuesday at Busch Stadium, but the Pirates finally found their way home, scoring a run in the fifth to take a 1-0 lead on the Cardinals.
Cardinals pitchers had blanked the Pirates for all 13 innings of the series up to that point, and had allowed a run in just one of the previous 26 innings before Pittsburgh scored. Prior to Mikolas' shutout on Monday, Arizona scored both of its runs in the ninth inning on Sunday and didn't score in the final four innings on Saturday.
