Quentin hits homer to give White Sox win

Carlos Quentin hit a tiebreaking homer leading off the bottom of the seventh Saturday, closer Bobby Jenks escaped a ninth-inning jam and the White Sox made it two straight over the Cubs with a 6-5 victory.

Quentin drove an 0-2 pitch from Carlos Marmol (1-3) for an opposite-field home run into the Cubs' bullpen in right field -- his 18th of the season -- to snap the 5-5 tie.

Derrek Lee was 5-for-5 with three RBIs for the Cubs, who've lost seven of 11. He led off the top of the ninth with a double and moved to third on an infield out.

But Lee was stranded when Jenks got Aramis Ramirez to groundout to short with the infield in and retired Jim Edmonds on a grounder to second to end the game.

Jermaine Dye and Alexei Ramirez also homered for the White Sox, who were swept last weekend by the Cubs but have rebounded and won four of five.

Matt Thornton (4-1), the third of five White Sox's relievers, pitched 1 2-3 perfect innings, striking out four of the five batters he faced to get the win. Jenks's save was his 18th in 21 chances.

Cubs starter Sean Gallagher worked six innings, giving up eight hits and five runs, including a two-run homer to Dye in the first and a tying solo shot to Ramirez in the fourth.

White Sox starter Javier Vazquez labored through 4 1-3 innings, allowing nine hits and five runs with three walks.

The Cubs scored two in the top of the first when the first four batters reached. Kosuke Fukudome walked and Mark DeRosa, Lee and Daryle Ward singled to give Gallagher an early two-run cushion he couldn't maintain.

Dye hit a two-out, two-run homer to tie it -- his eighth homer in the last 12 games and 18th of the season. After Jim Thome walked, Joe Crede doubled off the left-field fence and as the ball bounded past DeRosa, Thome scored for a 3-2 lead. Orlando Cabrera's RBI double made it 4-2 in the second.

The Cubs loaded the bases in the third on two singles and a walk, but Sox third baseman Crede made a fully extended catch of Geovany Soto's liner in the hole to end the inning.

DeRosa cut it to 4-3 by hitting an RBI single to score Mike Fontenot, who led off with a double in the fourth. Lee followed with a two-run double off the fence in left-center and the Cubs had a one-run lead against the struggling Vazquez, who needed 105 pitches to get through his 4 1-3 innings.

Ramirez, who missed Friday's game to be with his wife as she delivered their child, homered just over the left-center fence leading off the bottom of the inning to tie it.

Notes:@ White Sox 1B Paul Konerko, who is on the DL, took batting practice on the field Saturday and said he had some discomfort in his strained oblique muscle. Told by the team's training staff it was a normal reaction, Konerko will try it again Sunday and hopes to go on a rehab assignment next week. ... The Cubs put lefty reliever Scott Eyre on the 15-day DL with a groin strain Saturday. SS Ryan Theriot missed his second straight game and has a bruised hand but is expected to play Sunday night.
