PITTSBURGH -- Gregory Polanco homered, Chris Stewart added three hits and the Pittsburgh Pirates completed a four-game sweep of the NL Central-leading Milwaukee Brewers with a 4-2 victory on Thursday.
The Pirates have won 11 of 13 and moved within three games of Milwaukee in a division that's tightened up since the All-Star break. The Brewers have lost five straight, cutting their lead to one game over the idle Chicago Cubs.
Polanco hit a solo shot off Jimmy Nelson (8-5) in the fourth inning, his ninth homer.
