After inclement weather rained out Wednesday’s game, the Cardinals played their fifth doubleheader of the season Thursday at Busch Stadium. They rallied twice to win Game 1, 6-5, in ten innings, but fell short of another comeback in Game 2 and lost 7-5, splitting the twin bill and losing the series.
