Except for two teams, the Chicago White Sox have outscored their opponents 517-469 this season.
That's not great, but a +48 run differential is pretty good. With a little luck and a weak division, you can get into the postseason with a +48 run differential.
But after getting blasted (again) by the Tigers Monday night, the White Sox have been outscored 100-57 by Detroit this season. They've also been outscored 51-20 by the Yankees. That -- along with Adam Dunn and Alex Rios -- tells the story of the South Siders' 2011 season.
