Michael Wacha recovered well enough from Saturday's start against the Reds to get another turn in the rotation, as the St. Louis Post-Dispatch reports that he will face the Diamondbacks this weekend.
However, in the three starts Wacha has made since returning from time missed due to a stress fracture in his right shoulder, he has not had his usual success in employing his changeup. Cardinals manager Mike Matheny acknowledged that Wacha is having to rely on his other offerings, telling the Post-Dispatch, "For him to be able to try to pitch without what is normally his No. 1 weapon and hold a team down like he did takes some adjustment. He’s getting better."
According to BrooksBaseball.net, Wacha got swings-and-misses on 16.9 percent of his changeups in 15 starts prior to his disabled list stint. In the three starts since, he has induced only one whiff out of 21 changeups (4.8 percent).
