Cardinals starter Michael Wacha will start Game 1 of Wednesday's doubleheader against the Pirates, Bill Brink of the Pittsburgh Post-Gazette reports.
With Tuesday's game postponed due to weather, Wacha will simply move back to start the opener of what amounts to a critical doubleheader against the division rival Pirates. Instead of facing off against Charlie Morton as initially scheduled Tuesday, Wacha instead will take the mound against Gerrit Cole.
