Jedd Gyorko homered for the fifth straight game off San Diego pitching, connecting twice with all three RBIs in a 3-2 victory that gave the St. Louis Cardinals a doubleheader sweep Wednesday night.

Gyorko, dealt by the Padres in the offseason for outfielder Jon Jay, is 13 for 21 (.619) against his old team with six homers and 10 RBIs. He has 11 homers and 27 RBIs on the year with 40 starts spread across the infield. He started at third base both games of the doubleheader.

He has four consecutive three-hit games against San Diego and four career multi-homer games, with both long balls in Game 2 off Paul Clemens (1-1).

Carlos Martinez (9-6) was dominant after a shaky first inning and a nosebleed in the second, and the Cardinals took the opener 4-2. Gyorko, Matt Holliday and Yadier Molina homered off Colin Rea (5-4).

The Cardinals, just 23-28 at home, go for a four-game sweep Thursday night with ace Adam Wainwright facing Andrew Cashner.
