PITTSBURGH (AP) — 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 on 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. Wainwright followed with a drive to the gap in left-center to score both runners. He is hitting .261 this season, going 6 for 23 with four doubles, one triple and one home run.

The Cardinals added four more runs in the inning. Matt Adams hit an RBI double to extend his hitting streak to 10 games and scored on Jhonny Peralta’s single before Brandon Moss’ two-run homer, his 14th, capped the outburst.
