The bullpen limited Milwaukee to one hit and no runs in seven innings Friday night, and the Marlins rallied for their fifth consecutive victory, 6-5.
"We dug ourselves a hole early, but the bullpen was outstanding," manager Joe Girardi said.
Mike Jacobs doubled home a run in the first, then hit a two-run double in the third to help the Marlins overcome a 5-2 deficit.
"The whole year we've never really let a lead get us down," Jacobs said.
Florida starter Ricky Nolasco gave up seven hits and five runs in two-plus innings before departing with leg cramps, but the Brewers went hitless in the final 6 1/3 innings. Their best scoring chance against the bullpen came in the eighth, when pinch-hitter Jeff Cirillo popped out with two on to end the inning.
"Their pitching shut us down from the third inning on," Milwaukee manager Ned Yost said.
Borowski converted his 10th consecutive save chance to reach the 30-save milestone for the second time. Hampered by injuries in 2004-05, he had no saves last season.
"A couple of years ago I didn't know if I'd have an opportunity again to do something like this," he said. "It's very gratifying."
David Bush (9-10) twice failed to hold a lead, allowing eight hits and six runs in five innings. He hit two batters -- both scored -- to take over the major league lead with 17 hit batsmen.
Milwaukee's Bill Hall hit his 29th home run, but the Brewers fell to 23-40 on the road at the start of a seven-game trip. The game was the first between the teams this season, and the first of seven over the next 10 days.
Florida went ahead to stay with four runs in the third.
"That turned the game around right there," Bush said. "I'm disappointed I let the offense down. They did a good job to give me a lead to work with. I just couldn't hold it."
With the bases loaded, left fielder Gabe Gross got a poor jump on a deep fly by Jacobs, which landed near the scoreboard for a two-run double. The tying run came home when Miguel Olivo grounded into a fielder's choice, and Jeremy Hermida followed with a two-out, run-scoring single.
The Brewers, coming off a three-game sweep of Colorado, started fast by scoring in the first three innings. Laynce Nix's two-out RBI single in the first put them ahead.
Florida took a 2-1 lead in the bottom of the inning. Miguel Cabrera's RBI groundout scored one run, and Josh Willingham and Jacobs followed with back-to-back doubles.
Mike Rivera's RBI single in the second made it 2-all, and Milwaukee went ahead with three runs in the third. Prince Fielder led off with a walk, and Hall homered. Nix reached on an infield single, took second on a wild pitch and scored on a single by Gross, ending Nolasco's outing.
