Cardinals pitcher Michael Wacha has adjusted well to his new role as reliever. He's tossed three perfect innings since joining the bullpen, striking out seven of nine batters.
"He was pretty impressive, came in and did a nice job," Cardinals manager Mike Matheny said of Wacha's one-inning outing Saturday against the Cubs. "We knew we had to get him exposed at some point to some higher-leverage situations, and that was nice to get him in there and get us some big outs, more than anything else."
