Angels starter Ervin Santana struck out a career-high 11 batters and allowed just two hits over seven innings, as Anaheim defeated the visiting White Sox 6-2 Friday.
Detroit's game with Minnesota Friday was postponed, leaving the White Sox holding a 1.5 game lead over the Tigers in the AL Central race.
Chicago's recent offensive slump continued, as they've left 28 runners on base in their last four games. After sweeping the Twins in three games Sept. 14-16, and taking a make-up game over the Tigers as well as winning the first of a three-game set with Kansas City, the White Sox (81-69) have lost three straight.
Alejandro De Aza hit a solo home run in the first inning, but Chicago failed to score again until the 8th when Gordon Beckham singled, driving in Dayan Viciedo.
Jake Peavy (11-12) got the loss, fiving up five runs, all earned, in five innings.
