Michael Wacha was skipped over during the last turn of the rotation. The extra rest seems to be working out well.
Wacha has given up just four hits to the visiting Giants in his first six innings of work. He's also walked three (one of which was intentional) and struck out five while throwing 86 pitches.
Friday's outing is Wacha's 15th career start pitching on at least six days of rest. In the previous 14, Wacha is 5-2 with a 3.67 ERA.
At the plate, the Cardinals continue to be befuddled by opposing starter Matt Moore.
