Wacha will start Thursday in Game 4 of the ALDS against the Yankees, Anne Rogers of MLB.com reports.
Wacha had a rough outing in Game 1 on Saturday, allowing three earned runs on four hits and three walks over four innings en route to a loss. The 33-year-old righty is no stranger to poor postseason performances, as he owns a 5.36 ERA over 42 innings across nine playoff appearances in his career.
