Adam Wainwright matched his career high with 12 strikeouts in a five-hitter and the St. Louis Cardinals punished rookie Lucas Harrell with six runs in the first three innings, getting over an excruciating 19-inning loss two days earlier with a 7-0 victory over the Houston Astros on Tuesday night.
Skip Schumaker and Yadier Molina had two RBIs apiece for the Cardinals, who got six hits the first seven at-bats in a four-run first and then capitalized on a pair of walks to open a two-run third. Jon Jay had three hits and an RBI.
Wainwright (12-10) threw his second shutout and third complete game of the season. Two of the complete games have come during a string of six consecutive victories at home with a 1.42 ERA. He pitched a five-hitter on Aug. 4, a 6-1 victory over the Brewers.
