Pirates 5, Brewers 2: Pedro Alvarez belted a pair of home runs and Jeff Locke tossed six scoreless innings as visiting Pittsburgh evened the series at one game apiece.

Andrew McCutchen and Neil Walker connected on solo shots and Locke (5-1) permitted only three hits to win his fifth straight decision as the Pirates improved to 12-3 in their last 15 games.

McCutchen lined a shot into the seats in the top of the first inning for his fourth homer in 10 career at-bats against Fiers. Alvarez followed a single by Walker with another blast in the second for a 3-0 lead before Walker went deep in the fourth.

Locke made the lead stand up by extending his scoreless streak to 14 innings, marking the fourth time in seven outings that he has not allowed a run. Alvavez homered again in the ninth for a 5-1 edge.
