MILWAUKEE -- The Chicago Cubs came through with two outs.
Jacque Jones and John Mabry each hit two-out, two-run homers in the first inning, and Jones made a leaping-bases loaded catch to end the sixth in the Cubs' 6-3 victory over the Milwaukee Brewers on Tuesday night.
The Cubs scored all of their runs with two outs.
"We're just playing better as a team in those situations," Jones said. "Before, we weren't getting guys in, getting guys over and doing the job. It seems like guys are starting to relax a little bit more and letting the game come to us."
In the first game of a nine-game trip following an 8-3 homestand, the Cubs gave starter Carlos Marmol (5-5) all the runs he needed before he took the mound.
"I think that was huge for Carlos today to get that run support early," Cubs catcher Michael Barrett said. "That way, he could settle a little bit and pitch."
Ryan Dempster saved his 22nd game in 27 chances, dropping the Brewers a season-high eight games below .500.
"It's all about having good innings," Brewers shortstop Bill Hall said. "Unfortunately, right now it's just not happening for us."
After Tomo Ohka (3-3) retired the first two batters, Barrett doubled and Aramis Ramirez drove him in with an RBI single that dropped just short of center fielder Gabe Gross.
"It was a split instinct thing," Gross said. "It could've been a huge out for us, but I don't know if I could've had it."
Jones hit his 18th homer an estimated 442-foot drive over the Brewers bullpen, for a 3-0 lead.
"I was able to sit back and put a good swing on it," Jones said. "Everything felt good."
Matt Murton singled and Mabry, who had gone hitless in his previous nine at-bats, lined a pitch just over the wall in the right-field corner to make it 5-0.
Marmol allowed leadoff home runs in the second to Hall and the third to Gross. But Barrett added a two-out RBI double to give the Cubs a 6-2 lead and help chase Ohka, who gave up six runs and eight hits in four innings.
"When he's on, he's on, but when he's not he tends to struggle," Brewers manager Ned Yost said. "He made some mistakes."
Marmol, who allowed four hits and four walks, bounced back from one of his worst starts this season and showed his speed as a former minor league outfielder when he legged out a double leading off the sixth.
But Marmol never sat in the inning after being stranded and didn't make it through the bottom of the sixth, when he walked two and left with one out.
Michael Wuertz loaded the bases with a walk to David Bell and struck out Damian Miller, but pinch-hitter Jeff Cirillo lined a pitch just off Wuertz's glove, and the ball died in the infield as Kevin Mench scored and cut the lead to 6-3.
Wuertz was pulled for Will Ohman, and pinch-hitter Corey Hart hit a long fly ball to right field. Jones made a leaping catch on the warning track even though he had room to spare.
"I thought the wall was coming up on me," Jones said. "I was just trying to go back and get the ball at a key time of the game."
Barrett said Jones' play made the difference
"The momentum almost shifted and it was real close to the game taking a serious turn," Barrett said. "We were lucky to give up just one run in that situation."
