Cardinals pitcher Adam Wainwright, who hyper-extended his knee during his last start, showed no ill effects Sunday against the Pirates. He allowed three hits over eight scoreless innings, striking out seven and walking two in the 7-0 victory.
Wainwright improved to 5-1 while lowering his ERA to 1.20. He has not allowed an earned run since April 12.
Wainwright is scheduled to pitch Saturday at the Cubs.
