Bruce Chen outpitched Jake Peavy for his first win in 6 weeks, Billy
Butler hit his career-high 22nd homer, and the Kansas City Royals
beat the White Sox 5-2 on Tuesday night in
Chicago.

The White Sox had won 10 of 13 but saw their lead over Detroit in the AL Central shrink to a half-game with the Tigers beating the New York Yankees 6-5 earlier in the night.

Gordon Beckham hit his first career leadoff homer for Chicago, and the White Sox scored again in the sixth after Kansas City tied it in the top half. But RBI singles by Tony Abreu and Alex Gordon off Peavy (9-8) in the seventh gave Kansas City a 3-2 lead.
