After opening his career dazzling with a changeup-fastball mix, Wacha continues to flash an effective curveball and cutter, two pitches that he has further developed over the past year. He struck out third baseman Pedro Alvarez on a curve with two aboard to end the third. He stranded two more with a one-run lead in the sixth when Jordy Mercer popped up a cutter.
"I'm really happy with where everything is," Wacha said after allowing three runs (two earned) over six innings. "I'm just continuing to work on the command and control of them in between starts. I feel confident in all of them right now. Just continue to work on the command of them and when to throw them."
Wacha's enhanced repertoire has led to more early-count contact, which, in turn, has cut down on the strikeouts. That's by no means a concern to the Cardinals, but merely an indication of how much more versatile the right-hander can be. After striking out 159 over 171 2/3 innings in his first two big league seasons, Wacha has 19 over 38 2/3 to open this year.
Alvarez was his only strikeout victim on Friday.
"We like the strikeout, but it's not the definition, in our minds, of a successful outing," manager Mike Matheny said. "He's got the velocity. He's got the ability to strike somebody out. … The strikeouts are going to be there. I don't want to change a thing with him."
