Alberto Callaspo, David DeJesus and Miguel Olivo all hit three-run homers and the Kansas City Royals beat the Detroit Tigers 11-1 on Tuesday night.

The last-place Royals have beaten the AL Central-leading Tigers five straight times, four in the last eight days.

Robinson Tejada (3-1) beat the Tigers for the second time in less than a week, allowing one run and two hits in five innings.

Jarrod Washburn (9-9) allowed four runs in one inning — the shortest outing of his career. Washburn, who has been hampered by a sore left knee, is 1-3 with a 7.33 ERA in eight starts since being acquired from Seattle on July 31.
