C.J. Wilcox set career highs with seven 3-pointers and 31 points, including 21 in the second half, and Washington ran away from No. 15 Colorado for a 71-54 victory Sunday.

It was Washington's first win over a ranked team since Isaiah Thomas' jumper beat then-No. 16 Arizona in the 2011 Pac-10 Conference tournament championship game. Washington (11-6, 3-1 Pac-12) had lost 12 straight against ranked teams.

Colorado (14-3, 3-1) never recovered after leading scorer Spencer Dinwiddie crumbled to the court late in the first half after his left knee buckled while dribbling on a fast break. Dinwiddie had to be helped to the locker room by teammates and did not return.

The Huskies outscored the Buffaloes 49-29 after Dinwiddie's injury.
