White Sox defeat Cubs again, 6-5

CHICAGO -- Carlos Quentin hit a tiebreaking home run leading off the bottom of the seventh inning Saturday, closer Bobby Jenks escaped a ninth-inning jam and the White Sox made it two in a row 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 -- to break the 5-5 tie.

Derrek Lee was five for five with three runs batted in for the Cubs, who have 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 ground out to short with the infield in and retired Jim Edmonds on a grounder 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.
