Jake Peavy delayed Detroit's chance to move closer to the AL Central title, pitching the Chicago White Sox past the slumping Tigers, 8-0, Friday night in Detroit.
The Tigers went into the final weekend with a two-game lead over Minnesota but got off to a bad start when Scott Podsednik hit a leadoff home run.
Detroit lost for the fourth time in six games. Meanwhile, the Twins held on for a 10-7 victory over Kansas City, after leading 10-0, and cut the Tigers' AL Central lead to one.
If the Tigers fail to hold off Minnesota, they will become the first team in major league history to lead a division on May 10 and stay atop it until losing the title in the last week of a season.
