"When you look at the way I pitch, you barely do anything stiff-legged, so I'm going to be OK," said Wainwright, who still acknowledged a little discomfort, but only when the leg is fully extended.
Wainwright injured his right knee lunging for a bloop by Chris Young that landed between the pitcher's mound and first base Tuesday. Young's out, recorded by first baseman Matt Adams while Wainwright hobbled past the bag, ended both the seventh inning and Wainwright's night. Kevin Siegrist and Trevor Rosenthal finished the Cardinals' 2-0 win.
