Wacha Debuts Tomorrow

Cardinals prospect Michael Wacha is set to make his major league debut tomorrow night as the Cardinals and Royals wrap up their two-game series at Busch Stadium. The 21-year-old right-hander will be called up from Triple-A Memphis, where he was 4-and-0 with a 2.05 ERA in nine starts. Wacha was the 19th overall pick in last year's draft.
