Gregory Polanco's two-out, two-run home run in the eighth inning Sunday gave the Pittsburgh Pirates a 5-4 win and a sweep of their series against the visiting Milwaukee Brewers.

Polanco's fourth homer of the season came against Milwaukee reliever David Phelps (2-3) one out after Cole Tucker's one-out single.

Pittsburgh's JT Brubaker, making his third career start, gave up two runs and four hits, with six strikeouts and a walk. Chris Stratton (1-0) pitched a scoreless eighth. Richard Rodriguez pitched the ninth for his second career save and first of the season.

Milwaukee starter Corbin Burnes pitched 5 1/3 innings, allowing three runs and five hits with seven strikeouts and two walks.

Two Pirates left the game, first baseman Colin Moran (concussion evaluation) and shortstop Kevin Newman (abdominal muscle discomfort).

The Pirates made it 2-0 in the second. Polanco singled and stole second. Jose Osuna moved Polanco to third on a groundout, and Dyson followed with an RBI base hit to left.
