How it happened: Ryan Dempster and Jake Westbrook sailed through the first five innings before running into a wall in the sixth inning. Westbrook, who was perfect through five, walked three batters in the sixth, including Carlos Pena with the bases loaded. Marlon Byrd's two-run double and Starlin Castro's RBI single gave the Cubs a 4-0 lead after sending nine batters to the plate in the inning. Dempster didn't fare much better in the sixth, giving up a three-run home run to Lance Berkman, his 28th which leads the National League. Alfonso Soriano extended the Cubs' lead with a two-run home run, his second in as many days, in the ninth inning.
What it means: The Cubs broke a five-game losing streak and are now 1-5 on the 10-game road trip. Dempster won his eighth game which leads the team.
Outside the box: The Cubs did not make another trade as the deadline passed on Sunday. General manager Jim Hendry insists that he still has two months left to make waiver deals if it helps the Cubs future.
