Milwaukee Brewers lose 5-3 to Pittsburgh Pirates

MILWAUKEE — Jordy Mercer's first career grand slam capped a five-run sixth inning that started with two errors by Milwaukee third baseman Jonathan Villar, and the Pittsburgh Pirates held on for a 5-3 win on Friday night over the Brewers.

Villar bobbled a bouncer by Andrew McCutchen to open the sixth, then threw wildly to second after making a diving stab on Gregory Polanco's hard shot.

Starling Marte followed with an RBI double off starter Matt Garza (4-6) to break a scoreless tie. Three batters later, Mercer cleared the bases with his homer to left-center.

The Brewers rallied in the bottom of the sixth behind a three-run shot from rookie shortstop Orlando Arcia, his first in the big leagues.

Pittsburgh's problematic bullpen barely held on from there to back starter Ryan Vogelsong (3-3). Domingo Santana popped out to end the game with the potential tying run at second.

Tony Watson escaped the jam for his ninth save. He had allowed a two-out single to Ryan Braun and a walk to Chris Carter, and they pulled off a double steal.
