I think Chris Carpenter is the most pivotal player for the Cardinals. My earlier doubts about them were really about how he would pitch.
At least for one start, he's back, healthy, and dominant.
Joel Piñeiro won yesterday. Based on past history, I'm not confident that 6 2/3 innings of two run ball will be his standard outing, but a rotation of Carpenter, Wainwright, Lohse, Wellemeyer, and Piñeiro ain't bad. We just have to keep Carpenter healthy.
