Cardinals ace Adam Wainwright struck out 11 and allowed one run through seven innings, and Jon Jay drove in four runs with a homer and double to lead St. Louis to a 6-1 win over the Chicago Cubs on Sunday.
Matt Carpenter singled in two runs in the third to help back Wainwright (14-7), who was in command and allowed just five hits and one walk after going 0-2 in his previous four starts.
Junior Lake drove in the Cubs' only run with a double in the sixth.
Wainwright hadn't won since July 21 at home against San Diego and had allowed 14 runs in 28 innings during the span.
On Sunday, he faced only one batter over the minimum through the first five innings and only 26 through seven innings.
