JA Happ threw 5 1/3 shutout innings in the St. Louis Cardinals' 2-0 victory over the Cincinnati Reds on Sunday.
Nolan Arenado homered for the second game in a row and Happ combined with four other hurlers on a five-hit shutout.
St. Louis has won four of six. The Cardinals began the day two games behind Cincinnati and San Diego for the final NL wild-card spot. Cincinnati, which won the first game of the series, has lost five of seven.
Happ lasted just one inning and gave up seven runs on eight hits in a career-worst outing of a 12-2 loss at Cincinnati on Sept. 1.
Arenado hit a two-run homer in the first off Sonny Gray (7-7), who then retired the next 14 hitters. Arenado, who has 31 homers, also homered in the eighth inning of the Cardinals' 6-4 victory Saturday night.
Adam Wainwright (15-7, 2.98) will face New York Mets LHP Rich Hill (6-6, 3.82) on Monday in the first of a three game series in New York. Wainwright is 6-6 with a 4.95 ERA in 13 career starts against the Mets.
