ST. LOUIS (AP) - Matt Carpenter hit a sacrifice fly in the 11th inning Saturday and the St. Louis Cardinals once again beat the Pittsburgh Pirates 2-1 in extras.
The Cardinals have won five in a row. They defeated the Pirates 2-1 Friday night on Matt Adams' single in the 10th.
Pittsburgh left a season-high 18 runners on base and the Cardinals stranded just four. St. Louis has won 15 of its last 18 against the Pirates at Busch Stadium.
Peter Bourjos doubled in the St. Louis 11th. He was trapped off second by Jared Hughes (0-1) and caught stealing third. Pete Kozma and Jon Jay singled and Carpenter hit a deep fly to left that easily scored the winning run.
Carlos Villanueva (3-1), the seventh St. Louis pitcher, went one inning.
