MILWAUKEE -- Dave Bush was just wild enough to keep the Chicago Cubs off stride.
Bush took a no-hit bid into the sixth inning and the Milwaukee Brewers beat the Cubs 6-3 Wednesday night to stop a three-game losing streak.
"Bushie had good stuff," Milwaukee manager Ned Yost said. "He was effectively wild. He had trouble commanding his stuff at times, but made huge pitches when he needed to.
"He wasn't razor sharp ... but did a great job."
Bush (8-8) allowed three hits in eight innings, giving up his first when Juan Pierre beat out an infield single to shortstop with one out in the sixth. Michael Barrett was hit by a pitch with two outs, and Aramis Ramirez homered off the left-field foul pole, his 26th of the season.
"It wasn't enough," Ramirez said. "We were down six runs. It was a three-run home run to keep us in the game, but we just couldn't come back."
Cesar Izturis got the Cubs' other hit, a sharp single to right with two outs in the eighth.
Carlos Zambrano (12-5) lost his second consecutive start after going 9-0 with two no-decisions in June and July. He gave up six runs -- four earned -- five hits and four walks in 4 2-3 innings.
"I was feeling good today," Zambrano said. "I just left some pitches in the middle and we paid for that."
Zambrano had been 10-0 in 15 road starts since losing to the New York Mets on Aug. 7, 2005.
Staked to a 6-0 lead, Bush won at Miller Park for the first time since June 6 -- he had been 0-3 in four starts and one relief appearance. He struck out six, walked one and threw 103 pitches.
"I was aware of it," Bush said of his 5 1-3 hitless innings. "I was doing the best I could to get quick outs."
Bush hit Ramirez on the wrist on a pitch in the fourth, drawing a warning from plate umpire Ed Hickox. The right-hander said he wasn't trying to hit Ramirez, but had trouble locating pitches at times.
"Sometimes it's to your advantage," Bush said of his wildness. "Sometimes it helps a little bit."
Francisco Cordero pitched a perfect ninth for his fourth save in four chances since Milwaukee acquired him from Texas on July 28.
With two outs and none on in the third, Bush struck out but reached on Barrett's NL-leading ninth passed ball. Brady Clark followed with his first homer since June 7.
"It was a series of bad events," Chicago manager Dusty Baker said.
Prince Fielder and Gabe Gross walked in the fourth and scored on David Bell's single for a 4-0 lead.
Geoff Jenkins, who came into the game in a 4-for-38 slump, hit a two-out, two-run single in the fifth that chased Zambrano.
Brewers 2B Rickie Weeks will miss the rest of the season due to a tendon injury in his right wrist.
