CHICAGO (Ticker) -- Eddie Perez came as close as he could to obeying his mother's birthday wishes as the Milwaukee Brewers continued their strange mastery of the Chicago Cubs with a 9-6 victory.

Perez' mother spent her birthday in a hospital in Venezuela and likely will need heart surgery next week.

"I talked to her today and she asked me to hit two grand slams," Perez said. "I said 'Uh, OK Mom.' So I think they had her on drugs. Then I get here and the wind is blowing in."

Perez doubled his season total with five RBI as the Brewers scored six runs in the final two innings for the victory.

Perez got the comeback started with a three-run homer off Juan Cruz (1-1) in the eighth inning.

"The wind was tough and after I hit it, I was running hard until I saw the center fielder stop," Perez said. "Then I knew it was gone."

After John Vander Wal singled home the go-ahead run in the ninth off Mike Remlinger , Perez followed with an RBI single to make it 8-6. Royce Clayton knocked in the final run on a groundout.

"We gave them a couple of opportunities to get back in the game and sooner or later somebody will close the door," Remlinger said. "That doesn't make it easier right now."

The Brewers won 10 games against the Cubs last season, the most they had against any club in a 106-loss campaign. They have won the first two games between the clubs this year.

"I don't know what it is," Brewers closer Mike DeJean said. "I know that they are not taking us lightly and Dusty (Baker, Chicago's manager) would not let them do that."

Curtis Leskanic (2-0) pitched a perfect eighth inning to notch the victory.

DeJean threw one pitch to Alex Gonzalez in the ninth before the game was delayed 15 minutes by a problem with the lights. Once the game resumed, DeJean got Gonzalez to fly to right, then finished the inning with little difficulty to pick up his seventh save.

After several balls early in the game died at the warning track, Corey Patterson 's three-run blast off Wayne Franklin in the fourth inning made it into the right field seats to put the Cubs up 4-3.

"I just made adjustments," Patterson said of the blast on an 0-2 pitch. "I stepped out of the box and took a deep breath and tried to regroup myself and go on from there."

The Cubs tacked on runs in the fifth and seventh innings and seemed to be sailing smoothly until Perez' home run.

"This win was good for us because we have battled so hard," Brewers manager Ned Yost said. "When you do that, you need to get the reward once in a while."

Franklin gave up five runs and six hits in 4 2/3 innings. He struck out three and walked one.

The Brewers got on the board in the second inning when Royce Clayton brought Geoff Jenkins home with a sacrifice fly.

The Cubs evened the score in the bottom of the inning when Alex Sanchez came in too far on Patterson's fly ball to center field and had to jump to try to catch it. Mark Bellhorn raced around to score from first and Patterson went to third base when the ball glanced off Sanchez' glove and sailed past him.

Cubs starter Mark Prior allowed three runs - one earned - and five hits in six innings. He struck out seven and walked two. Prior is third in the National League with 52 strikeouts.
