CHICAGO -- Carlos Lee gave the rookie some advice on how to face Greg Maddux.
The Brewers bounced back after dropping two of three games against the Kansas City Royals, the team with the majors' worst record.
Fielder hit one of the three homers Maddux allowed.
"I told him look for the ball up and just be aggressive," Lee said. "What he kind of does is play around with you, soft, soft, soft, in and out."
The troubles continue for the Cubs, who have lost eight straight at home.
It is their longest losing streak at Wrigley Field since dropping 12 in a row to start the 1994 season. The Cubs, who have scored a total of two runs in their last three games, have lost 11 of 13 overall and have not won at home since beating Cincinnati on May 30.
"It's frustrating, but it is still baseball," Maddux said. "It's still the greatest job in the world even when things are going tough. It's still a privilege to come to the park every day, you just wish you were playing better and winning more."
Maddux wouldn't elaborate on the overall feel for the team.
"I think what happens in the clubhouse stays in the clubhouse, to be honest with you. I think for myself or any other player to say what goes on in the clubhouse when the doors are closed is just wrong," he said. "Obviously, I'm not the only one that's upset and we just need to go out there and try to do what we can to play better."
Milwaukee starter Chris Capuano won his fourth consecutive decision and Gabe Gross added a two-run homer.
Capuano (9-4) allowed seven hits, walked two and struck out four. He left the game in the ninth inning after being hit on the right arm by a line drive from Aramis Ramirez. The team said he had a bruised forearm and would be evaluated Tuesday.
"I like pitching here because of the atmosphere, because of the fans and the history," said Capuano, who also pitched a shutout at Wrigley on April 30. "I think a lot us, it's almost fans when we come in here. We're players, but we're also baseball fans. It's just exciting to play here."
Derrick Turnbow relieved and got the final three outs in the Brewers' third shutout of the season. Two of those have been against the Cubs.
After a two-out single by Geoff Jenkins in the first, Lee hit his 24th homer on an 0-2 pitch from Maddux.
Fielder homered to right-center off Maddux (7-8) in the seventh and Gross added his homer later in the inning.
Fielder connected off Will Ohman in the ninth for his 16th homer of the season. It was the third multihomer of his career and two have happened at Wrigley Field.
"I don't know if it's this ballpark. Just luck I guess. I just tried to hit the ball up the middle and let the rest take care of itself," Fielder said.
Maddux, stuck on 325 career wins, gave up five runs and seven hits in seven innings and lost for the eighth time in 11 starts. After starting the season 5-0, Maddux is 2-8 with a 6.78 ERA since May 3.
Maddux tied a season-high with seven strikeouts, but was burned by the long ball despite the wind blowing in.
"They just hit them through the wind, plain and simple. You can hit them through the wind here and they proved it," Maddux said. "I felt fine, everything was going well except for the fact that I couldn't keep the ball in the ballpark."
Derrek Lee got a nice ovation when he stepped to the plate in the first inning Monday night. He played his first game at Wrigley Field since April 13. He missed 59 games after breaking his wrist on April 19 at Los Angeles. The Cubs went 9-5 with Lee in the lineup before the wrist injury, but were 19-40 without him. Lee finished 2-for-4.
The original plan was for Lee to play two rehab games at Triple-A Iowa before joining the club on Monday. But after Freddie Bynum and Tony Womack were injured Saturday night, Lee made the four-hour drive from Des Moines to Minneapolis on Sunday and went 1-for-4 with a single and two strikeouts as the designated hitter.
RHP Kerry Wood visited Dr. Tim Kremchek in Cincinnati on Monday. Kremchek operated on Wood's shoulder last August. Wood threw a side session while hooked up to equipment for biomechanical analysis. "The MRI in Dr. Kremchek's terms, stated it was pristine, that the labrum repair looked as if it was completely intact, looked like it had healed nicely and perfectly. He said his rotator cuff looks pristine, the joint looks good. So there is no significant concerns of any kind of significant issue or injury or anything like that," trainer Mark O'Neal said. Wood is back on the disabled list after making just four starts. ... Jenkins robbed Matt Murton of a hit with a diving catch in right field in the eighth.
