ST. LOUIS (AP) - St. Louis starter Michael Wacha pitched six innings and Jedd Gyorko drove in the lone run with one of his three hits Friday night, leading the Cardinals to a 1-0 victory over the Arizona Diamondbacks.
Wacha (8-4) allowed three hits. He has won five of his last six starts and improved to 7-1 in 12 starts at Busch Stadium this season.
Wacha finished strong. He pitched out of a jam in the sixth. He gave up a single and double with two outs before striking out David Peralta to end his night.
Trevor Rosenthal, the third reliever for St. Louis, earned his fifth save with two innings of work.
Arizona starter Robbie Ray left the game in the second inning after getting hit in the head by a line drive off the bat of rookie Luke Voit. The ball caromed in the air into foul territory where third baseman Daniel Descalso caught it for the out.
Ray lay prone on the mound for several minutes before sitting up with his teammates surrounding him. He was driven off the field on a cart and was taken for an examination.
