PHOENIX -- Milwaukee left fielder Ryan Braun is booed every time he is announced at Chase Field. He added to the animosity Saturday.

Braun hit a pair of three-run homers and tied a franchise record with seven RBIs, and Keon Broxton had five hits in the Brewers' 15-6 victory over the Arizona Diamondbacks.

"It's a non-factor me," Braun said. "Regardless of the reception, I'm doing my best to compete as hard as I can and do my best."

Braun's three-run homer off reliever Evan Marshall in the sixth inning gave the Brewers a 5-0 lead, and his three-run homer in the seventh off reliever Dominic Leone made it 9-0.

"He had a great night," Milwaukee manager Craig Counsell said. "They were both impressive homers. But for me, the first one to me was the game was us."

Braun had a sacrifice fly in the first inning and singled in a six-run ninth as the Brewers scored 13 runs in the final four innings.

"We don't get too opportunities with guys in scoring position," Braun said. "When we do get them, it is important we are able to get those guys in, especially in this ball park."

Braun was the NL MVP in 2011 when the Brewers beat Arizona in the NL Division Series but later was reported to have failed a drug test that season. He was suspended for half a season in 2013 for violating baseball's drug policy.

Marshall hit Braun with a pitch and was ejected when the Brewers played in Arizona on June 17, 2014, and received a fist-bump from then-manager Kirk Gibson as he left the field.

Braun, who has 18 homers and 56 RBIs, also had seven RBIs on April 8, 2014, at Philadelphia.

"It's such a challenging game," Braun said. "We deal with so much failure, so much adversity. So when you have those rare games that are special, like tonight, you definitely have to appreciate those."

Broxton had four singles and a double and had two RBIs, and Jonathan Villar had four hits and two RBIs for the Brewers (49-59), who have won six of nine.

"Villar has been a machine, he really has," Counsell said.

Orlando Arcia and Hernan Perez had two hits apiece for the Brewers, who had season highs in runs and hits (19). Arcia scored four runs.

Arcia and Villar scored ahead of Braun's homers.

Milwaukee right-hander Matt Garza (3-4) gave up three runs (two earned) and won his second straight start while pitching into the seventh inning for the first time this season.

Garza gave up three hits, struck out three and walked three in 6 1/3 innings.

"I've been saying for some time that I've been looking for my stuff," Garza said. "About two, three starts ago I found something. I've been running with my stuff since then."

Welington Castillo hit a two-run homer to end Garza's shutout in the seventh inning, and Jean Segura hit a two-run homer later in the inning off reliever Jhan Marinez to make it 9-4.

Yasmany Tomas singled and has hit safely in his last 12 starts for the Diamondbacks (44-66), who have lost five of six and are 18-39 at home.

Paul Goldschmidt and Jake Lamb had RBIs in the ninth inning.

"We had a hard time getting a few guys out -- Braun, Broxton, Villar," Arizona manager Chip Hale said. "That is just not good. We did not perform like we need to."

Arizona left-hander Patrick Corbin (4-11) gave up four runs and eight hits in five-plus innings. Corbin is 0-8 with a 6.93 ERA in 11 home starts.
