Pitcher Adam Wainwright, pinch-hitting because the Cardinals were out of positon players, hit a two-run, two-out double to spark a six-run 12th inning as St. Louis beat the Pittsburgh Pirates 9-3 Friday night.

Wainwright batted for reliever Jonathan Broxton after Matt Carpenter drew a two-out walk from Juan Nicasio and Pirates manager Clint Hurdle decided to intentionally walk Alemdys Diaz to bring up Broxton's spot in the order.
