SAN FRANCISCO -- The Giants have won two of the last four World Series titles by getting hot at the right time of the year.
They'll enter September as hot as they've been all season after beating the Milwaukee Brewers 15-5 on Sunday to complete a three-game sweep and win their sixth straight game, matching a season high.
The victory capped a 6-1 homestand and led to the Giants' first winning month since May. They went 16-12 in August, and their 9-3 record at AT&T Park is their best month at home this season.
"There's no reason or anything I can give you on why we did struggle here," manager Bruce Bochy said. "I think we're seeing more of the club that we are. We played well here early in the season, so I think it was important that we have a good homestand."
The Giants entered the month having lost 21 of their previous 28 home games, but the recent boost has them back in the thick of the National League West race at 74-62. They trail the Los Angeles Dodgers by 2½ games and have a one-game lead for the top wild-card spot.
While Madison Bumgarner (16-9) continued the Giants' run of terrific starting pitching with six innings of one-run, five-hit ball, the story was the offense.
The Giants exploded for a season-high 15 runs, two days after scoring a then-season-high 13 runs. They accumulated 10 extra-base hits, the most they've had at AT&T Park since it opened in 2000.
Pablo Sandoval finished a double shy of hitting for the cycle, Hunter Pence had four hits and rookie catcher Andrew Susac was 3 for 5 with three RBIs.
Sandoval, Pence and Joe Panik all tripled, the first time the Giants have had three triples in a home game since 1977. While Bochy continually expressed optimism throughout the team's earlier home struggles, this wasn't quite what he had in mind.
"I really thought we would turn it around," he said. "If you're asking me if I thought we'd score this many runs? No. This is a pitcher's park. A lot of those close games, I thought we let get away from us. It's good to see the guys having some confidence at the plate here at home."
Susac's day was among the most encouraging. Bochy wanted to give Buster Posey a day off to rest some general soreness and said Susac's success was one reason he was comfortable doing so even with ace Bumgarner on the mound.
Bochy was rewarded with Susac's two-out RBI double in the second inning to score the first run, which prevented the Giants from wasting Sandoval's leadoff triple. Susac added another double and a single for the first three-hit game of his big league career and his second with three RBIs.
Susac's been up for just over a month but said this homestand felt like one that showed the type of team the Giants have.
"I've been waiting for that one series to stick out where the pitching and the hitting clicks," Susac said. "Man, we put up some good numbers this weekend, and it was fun to watch our starting pitchers."
Bumgarner tied a career-high in picking up his 16th win, which also tied him with the Dodgers' Clayton Kershaw and Cincinnati's Johnny Cueto for the major league lead. Bumgarner likes where the team is at, particularly with a clubhouse filled with players who have experienced success down the stretch of a season and in the playoffs.
"If you finish the year strong going into the playoffs, we've shown what we can do in the postseason in '10 and '12," Bumgarner said. "Whatever the reason, I'm glad we've got the guys that know how to do that."
The Giants purchased the contracts of infielder Chris Dominguez and catcher Guillermo Quiroz from Fresno and transferred Ehire Adrianza and Hector Sanchez to the 60-day disabled list to create 40-man roster spots to do so.
