Pirates 7, Marlins 2

PITTSBURGH -- Edinson Volquez continued his mastery of Miami, allowing one hit in seven scoreless innings, and rookie Gregory Polanco drove in four runs to lead Pittsburgh.

The right-hander improved to 6-0 with a 1.64 ERA in seven career starts against the Marlins. He struck out seven and walked three as he won for the first time in four starts since the All-Star break after winning his last four starts of the first half.

The Marlins had a scary moment in the seventh inning when Pirates shortstop Jordy Mercer hit a line drive off the right side of left-handed reliever Dan Jennings' head. The ball struck Jennings with such force that it popped into the air and was caught behind second base by shortstop Adeiny Hechavarria.

Right fielder Giancarlo Stanton hit his National League-leading 27th home run, a two-out shot off rookie right-hander Stolmy Pimentel, to help the Marlins avoid being shut out.
