Cardinals starting pitcher Adam Wainwright earned his second complete-game victory of the season in the second game of a day-night doubleheader Saturday night against the Giants.

Wainwright (8-3) allowed a run-scoring single to Andres Torres in the seventh inning for his only damage of the night. He allowed one run on eight hits while striking out 10 in a 7-1 victory.

Wainwright has pitched eight-plus innings in three of his last five starts. He has allowed eight runs in his last 39 1/3 innings. He'll make his next start Thursday at home against Arizona.
