Mike Burns (2-2) struck out a career-high seven and drove in a run to win for the second time in his career while in the rotation for the injured Dave Busch.
The Brewers had lost seven of ten and the 55-32 Dodgers slipped to 5-3 on their nine-game trip.
With one out in the first, Weaver served up a triple to Craig Council but he was caught between third and home on Ryan Braun's ground ball. Furcal's throw to the plate skipped through Russell Martins' legs and Braun moved to second, then scored on Fielder's single.
The Dodgers hits were well scattered; A single by Casey Blake in the second, a single by Weaver in the third and Manny Ramirez's single in the fourth.
Weaver stranded runners on base in each of the next two innings, but made what he called his only mistake of the night in the fourth inning on a solo homer by Frank Catalanotto, one of four straight Brewers hits to open the bottom of the fourth. Quickly the Dodgers were down 4-0. Ramirez made a nice recovery and throw to nail a runner attempting to stretch a single into a double to end the inning.
Scott Elbert, just recalled when Jonathan Broxton finally confessed that his toe was bothering him again, stepped in and closed the door at that point, also shutting the Brewers down over the next two innings.
Los Angeles roused themselves and scored three in the fifth with two out.
With one out Kemp singled and with two out Furcal and Ethier homered back to back. Loney added a single in the sixth and pinch-hitter Juan Castro singled with two out in the seventh. But that was the Dodgers' final gasp.
"We put pressure on them when we got close, but that's as close as we got," Dodgers manager Joe Torre said.
Ramirez went 1-for-4 to extend his hitting streak to five games. He is 8-of-26 (.308) with three homers, nine RBIs and six runs in eight games since returning from his 50-game suspension.
The Dodgers were looking for something better out of Weaver after receiving bad news regarding left-hander Eric Milton, who was placed on the disabled list with a strained back had a setback that could be a "long term" situation.
Broxton to Miss All-Star Game
Dodgers closer Jonathan Broxton will miss the All-Star Game with discomfort in his right big toe, after Torre and third-base coach Larry Bowa noticed Broxton limping off the field after the Dodgers beat the Brewers Friday.
"We interrogated him [Friday] night and finally got it out of him," Torre said. "It's been bothering him since Sunday, so he's not going to be available for us."
Torre called All-Star manager Charlie Manuel and alerted him of Broxton's condition. The area causing Broxton discomfort is on the side of his right big toe -- the foot the right-handed pitcher uses to push off the rubber.
Left-hander Scott Elbert was recalled from Albuquerque. Los Angeles optioned Blake Dewitt to Albuquerque to make room for Elbert.
Guillermo Mota was chosen to fill in at closer came in with one out in the bottom of the eighth on Saturday with the Dodgers trailing by a run, only to give up a two-run double to J.J. Hardy in the 6-3 loss.
Broxton's past two outings have been out of the ordinary for the 25-year-old closer, who is tied for sixth in the National League with 20 saves. He allowed three other runs to the Padres in an eventual 7-6, 13-inning win and gave up two runs in the bottom of the 10th in the first game of the series, but the Dodgers hung on for the win.
In the final game before the All-Star break, the Dodgers will send LHP Clayton Kershaw, LHP (6-5, 3.27) to the mound. The 21-year-old worked six scoreless innings on his last start against the Mets. He has now allowed only two earned runs in the past 29.2 innings (0.61 ERA) covering five starts.
The Dodgers will face RHP Yovani Gallardo, RHP (8-6, 2.95), who put up All-Star numbers in the first half of the season, but was not selected. In his last start against the Cardinals he was tagged for four runs on six hits, including a pair of homers in five innings.

Att- 43,466.Dodger Blue Notes-- Torre said left-handed starter Eric Milton, who recently went on the 15-day disabled list with a strained back, "is not good." The skipper said Milton was running in the outfield at New York's Citi Field on Thursday when he did something to cause more pain in his lower back. Milton told Torre he has had similar back situations throughout his career, but nothing compared to the current pain. Torre said the injury, "looks like it's going to be long-term." ...Along with three of his players, Torre will also make the trip to St. Louis for the All-Star Game as part of NL manager Charlie Manuel's coaching staff. Torre, who played six seasons for the Cardinals, said that St. Louis holds a special place in his heart. He said he matured as a person with the Cardinals and was disappointed when he had to move on. "It may have been one of the biggest disappointments in my career there when I had to leave there," said Torre, who also managed the Cardinals in the first half of the 1990's. "I remember writing a letter to [the Busch Family] expressing my sadness for leaving and not being able to be part of a championship club." ... After Matt Kemp hit a grand slam to put the Dodgers up six runs on Friday night, Torre told Ramirez to head to the clubhouse for an early night. Even with the early departure, Ramirez almost had to come back. "I told him, 'That's it for you' once we scored those runs and [bench coach Bob Schaefer] had to go get him, because we had to have him out on deck in case he came up again, because I couldn't use another player," Torre said. "He put his uniform back on, and I said, 'I don't care if you take three strikes -- I can't use another player.' But it didn't matter."
