CHICAGO (Ticker) -- After red-hot Aaron Rowand came through with a clutch hit, ice-cold D'Angelo Jimenez provided the game-winner.

Rowand erased a two-run deficit with an eighth-inning homer and Jimenez plated the winning run in the ninth with a two-out single as the Chicago White Sox edged the Chicago Cubs , 7-6.

Rowand had eight hits in 20 at-bats since his recall from Class AAA Charlotte on June 10 but was hitless in his first four at-bats in this one. But with the White Sox trailing, 6-4, in the bottom of the eighth, he crushed a 1-1 pitch from Antonio Alfonseca over the left field fence.

"I just wanted to go out and do something to try and help us win. I hadn't done much until then," Rowand said. "I was just trying to get in a rhythm, that's really it. My swing feels good now."

Juan Cruz (1-3) took over for Alfonseca in the ninth and issued a leadoff walk to Magglio Ordonez . After Ordonez took second on a flyout, Mike Remlinger relieved and struck out Jose Valentin . Tony Graffanino was intentionally walked and Jimenez, who came on in the eighth inning, singled up the middle to score Ordonez easily.

"A change-up that was down, I probably should have caught the ball," Remlinger said of the decisive pitch.

Jimenez had just 11 hits in his previous 70 at-bats and was 0-for-13 against the Cubs this season.

"That was a big hit for Aaron Rowand ... as big a hit as we had the entire game," White Sox manager Jerry Manuel said. "Then it was a great moment for D'Angelo as well. ... I'm sure he needed that after the last couple of weeks."

One day after blowing a save, White Sox closer Billy Koch (4-4) tossed a perfect ninth and was rewarded with a second straight win.

Bartolo Colon started for the White Sox and was tagged for six runs and six hits in 5 1/3 innings. He matched a career high with seven walks, threw just 50 of 98 pitches for strikes and fell to 8-2 with a 6.08 ERA in his last four starts.

David Sanders followed Colon and got an out in the sixth. Rick White allowed a hit over two scoreless frames and Damaso Marte got the final out in the eighth.

The White Sox have taken four of five meetings from the Cubs this season and have won six of eight overall.

"The team that we are right now, that's the team we expected to be," Jimenez said.

The game was delayed 36 minutes by rain in the top of the seventh inning.

Cubs starter Carlos Zambrano allowed four runs and seven hits in six frames. Despite his shaky outing, the hard-thowing righthander has a 2.73 ERA over his last nine starts.

The Cubs have dropped four straight and seven of nine.

"It's been a tough week," manager Dusty Baker said. "You can't say anything tonight (about the loss). We have to come back and salvage something. We'll get it together."

"It's a tough time for all of us," Remlinger added. "All we can do is play hard and not quit."

Eric Karros had three RBI and Troy O'Leary had two hits and drove in a pair of runs for the Cubs.
