ST. LOUIS (AP) Beau Taylor and Matt Chapman homered, and Daniel Mengden pitched six scoreless innings to lead the Oakland Athletics to a 2-0 win over the St. Louis Cardinals on Wednesday night.
Mengden (2-1) gave up four hits and struck out five for his first win since May 18 at Detroit. He took the starting rotation spot of Frankie Montas, who was suspended 80 games June 21 for testing positive for a performance-enhancing substance.
Yusmeiro Petit pitched the seventh, Joakim Soria the eighth and Liam Hendriks got the last three outs for his second save in four chances. Hendriks has not allowed a run in 23 of his last 25 appearances.
Oakland got its fifth shutout of the season - first on the road - and first since May 7 against Cincinnati.
Adam Wainwright (5-7) allowed two runs and seven hits in 6 2/3 innings with nine strikeouts.
St. Louis was shutout for the sixth time this season, and the third time in its last 14 games.
Taylor homered into the Cardinals' bullpen in right-center field in the fourth inning. It was his second home run in seven starts.
Chapman chased Wainwright from the game when he got his team-leading 19th homer into the Athletics' bullpen in left-center.
