Carlos Beltran added two RBI and Pete Kozma drove in a run for the Cardinals, winners in eight of their last 10 games.

Everth Cabrera had two hits and two RBI and Chase Headley added a pair of hits and an RBI for the Padres, losers in 15 of their last 17 games.
"I thought early on we had some decent swings, we just hit the ball to some guys," Headley said. "After the first time through (Westbrook) really settled in and just did what he usually does."
Beltran's sacrifice fly in the third inning scored Westbrook to give St. Louis a 1-0 lead.
The Padres wasted a bases-loaded opportunity in the fourth when Nick Hundley grounded into a double play.
