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. Wilcox topped his previous high of 30 points set earlier this season against Boston College.
But the surprising part wasn't Wilcox getting hot or the improving Huskies knocking off a ranked opponent playing short-handed after Colorado star Spencer Dinwiddie went down with a knee injury in the first half.
The shock was the length in time since the Huskies had beaten a ranked opponent. 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. The last time Washington beat a ranked team in the regular season was a home win over Texas A&M in December 2009.
No. 1 Arizona 73, USC 53 • In Los Angeles, Brandon Ashley and T.J. McConnell each scored a season-high 19 points and Arizona beat USC to improve to 17-0 for the best start in school history.
Nick Johnson chipped in 15 points and Aaron Gordon had 12 for the Wildcats, the second straight game they've had four players reach double figures in scoring.
The 1931-32 Wildcats held the previous school record for best start at 16-0.
No. 20 Iowa 84, No. 3 Ohio State 74 • In Columbus, Ohio, Roy Devin Marble scored 22 points, Aaron White added 19 and Iowa ended the game on a 22-9 run to hand Ohio State its second loss of the week. Melsahn Besabe had 11 points and 10 rebounds, Mike Gesell added 11 points and Jarrod Uthoff had 10 off the bench for the Hawkeyes (14-3, 3-1 Big Ten), who ended a string of eight straight losses to the Buckeyes.
