Giants 15, Brewers 5: Pablo Sandoval homered among three hits and drove in three runs as host San Francisco extended its winning streak to six games by completing a three-game sweep of Milwaukee.

Hunter Pence went 4-for-5 with with a pair of RBIs and Andrew Susac matched Sandoval with three hits and three RBIs as the Giants remained 2 1/2 games behind the first-place Los Angeles Dodgers in the National League West. Madison Bumgarner (16-9) tied his career high for victories and moved into a tie for most wins in the majors by allowing one run in six innings while winning his third straight start to send the reeling Brewers to their fifth consecutive defeat.

Kyle Lohse (12-8) was pounded for seven runs on nine hits over 5 2/3 innings for skidding Milwaukee, which dropped into a tie with St. Louis atop the NL Central. Ryan Braun and Martín Maldonado homered for the Brewers, who have scored 11 runs during the five-game slide.

After spotting Milwaukee a 1-0 lead courtesy of Braun's double-play grounder in the first, the Giants went to work on Lohse in the second with a leadoff triple by Sandoval and Susac's run-scoring double. Pence had an RBI double in the fourth and Sandoval and Michael Morse plated runs to extend the lead to 4-1.

Pence, who extended his hitting streak to 13 games and was a homer shy of the cycle, doubled in the fifth and Sandoval followed with a towering shot to right field that one-hopped into McCovey Cove for a 6-1 edge and left him a double shy of the cycle. San Francisco poured it on with seven runs in the seventh, getting a two-run double from Susac and a two-RBI triple from Joe Panik.
