Adam Wainwright threw a bullpen session and said his right knee feels good enough to allow him to make his next scheduled start Sunday against the Pittsburgh Pirates.

The right-hander left a win over the New York Mets after hyper-extending his right knee while lunging for Chris Young's flare between the mound and first base.

Wainwright said Thursday his knee was "a hair sore -- on fully extension only."

"And when you look at the way I pitch, you barely do anything stiff-legged, so I'm going to be OK," he said.
