MIAMI (AP) — Pittsburgh Pirates rookie Gregory Polanco had five hits Friday night, and the last one was the biggest — and the longest.
Playing in his fourth major league game, Polanco broke a tie in the 13th inning with his first homer, helping Pittsburgh to an 8-6 victory over the Miami Marlins after the Pirates had a ninth-inning meltdown.
Polanco went 5 for 7, scored three times and made a run-saving catch in right field.
"That could have been a coming-out party for him," manager Clint Hurdle said. "Very exciting to watch. I hope we get to watch for a long time."
Clint Barmes singled off Mike Dunn (5-4) to start the 13th and advanced on a sacrifice. Polanco homered on a hanging 2-2 slider and smacked his hands as he circled the bases, mindful his mother was in the stands watching him for the first time since he played winter league in his native Dominican Republic.
"For sure this is my best game ever — the first time she's here watching me play," Polanco said. "I was excited and a little emotional. She's so proud of me, and I know she's feeling excited right now."
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.
Miami trailed 6-5 and had runners at first and third with two out in the ninth when Hurdle ordered NL home run and RBI leader Giancarlo Stanton intentionally walked. The strategy backfired when Casey McGehee fell behind 0-2, and then walked against Mark Melancon to tie the game.
Melancon struck out Marcell Ozuna to send the game to the 10th.
"You rip off the rearview mirror and keep playing," Hurdle said.
The Marlins stranded three in the ninth and two in the 12th.
"The game was there for the taking at the end," McGehee said. "It was unfortunate we couldn't quite finish it off."
Pittsburgh's Sterling Marte homered and tied a career high with four hits. Ike Davis added a two-run double, and the top four hitters in the Pirates' order went 13 for 27.
The Pirates have won seven consecutive series openers, and on Saturday they have a chance to reach .500 for the first time since mid-April.
