With the retractable roof open and the Milwaukee Brewers in town, pitcher-friendly Marlins Park became a launching pad.

Mark Reynolds hit a pair of two-run homers and the Brewers won a record-setting slugfest at spacious ballpark, beating Miami 9-5 Friday.

Giancarlo Stanton and Garrett Jones hit two solo homers apiece for Miami, and Khris Davis homered for Milwaukee. The teams combined for seven home runs, the most since their park opened in 2012.

"I think having the roof open helps," Reynolds said.

Brewers manager Ron Roenicke wasn't so sure.

"It's hard to say," he said. "My gosh, there were some long home runs by both sides. Those balls were crushed. There were a lot of fireworks going on."

Milwaukee didn't need slugger Ryan Braun, who sat out after a flare-up of the oblique strain that sent him to the disabled list earlier this season. The Brewers hope he can rejoin the lineup by Sunday.

Reynolds homered in the fourth and again in the fifth, increasing his season total to 11. It was his 20th career multihomer game.

Miami lost despite hitting a season-high four home runs. Stanton's two tape-measure homers increased his season total to 14, most in the NL, and his 47 RBI lead the majors. It was his 12th career multihomer game, tying Hanley Ramirez's franchise record.

Even so, Miami fell to 5-17 against the Brewers since the start of 2011.
