How it happened: White Sox starter Jake Peavy allowed six runs and left the game after just 2 1/3 innings with pain in his left ribs. The White Sox got off to a good start in the top of the first when Conor Gillaspie's RBI groundout brought home Alejandro De Aza. But the Mariners answered with three runs in the bottom half, the big blow coming on Raul Ibanez' two-run home run. Adam Dunn pulled the Sox back within a run in the second inning with his 13th homer of the year. But Ibanez struck again in the third, smacking a two-run double and later scoring on Nick Franklin's double. The White Sox battled back in the eighth, finally chasing Mariners starter Felix Hernandez. Alexei Ramirez singled to right to start the inning and came home on a double by Tyler Flowers. Hernandez was then relieved by Oliver Perez, and was greeted with an RBI single from De Aza. The threat ended when Gordon Beckham grounded into a double play. The Mariners tacked on an insurance run in the eighth when Michael Saunders scored on pinch hitter Kelly Shoppach's sacrifice fly.
What it means: The White Sox’s season-worst losing streak reached eight games. It’s also their first nine-game road skid since May 30-June 22, 2008.
Outside the box: After leaving the game, Peavy underwent X-rays, which were negative for a fracture, and he will have an MRI on Wednesday in Seattle, according to the team's website.
Up next: The White Sox will send Dylan Axelrod (3-4, 4.04 ERA) to the mound against the Mariners’ Hisashi Iwakuma (6-1, 2.13) in the series finale at 2:40 p.m. CT Wednesday.
