A.J. Burnett remained undefeated against the Cincinnati Reds this season and Starling Marte hit a tiebreaking two-run triple to help the Pittsburgh Pirates salvage the finale of their three-game series with a 6-2 win on Sunday.

Neil Walker hit a two-run home run and All-Star center fielder Andrew McCutchen added a solo shot as Pittsburgh snapped Cincinnati's win streak at five and cut the Reds lead in the National League Central Division to 4 1-2 games.

Burnett (14-3) allowed just one hit after the first inning and retired 18 straight batters before yielding two walks with two outs in the ninth. He allowed three hits and two runs with three walks and seven strikeouts in 8 2-3 innings to improve to 3-0 in three starts against the Reds this season.

Joel Hanrahan got the final out for his 32nd save.
