Gregory Polanco broke a tie in the 13th inning with his first major league homer, and the Pittsburgh Pirates overcame a ninth-inning meltdown to beat the Miami Marlins 8-6 Friday night.
Polanco, playing in his fourth big league game, went 5 for 7, scored three times and made a run-saving catch in right field.
Clint Barmes singled off Mike Dunn (5-4) to start the 13th and advanced on a sacrifice. Polanco homered on a 2-2 pitch.
Jeanmar Gomez (1-2) pitched four scoreless innings after the Pirates blew a 6-2 lead in the ninth when three relievers combined to issue six walks. The Pirates' Jeff Locke pitched a career-high eight innings, and the bullpen's wildness cost him his first victory since Sept. 12.
