No. 1 Arizona 71, Washington 62: Nick Johnson scored a career-high 24 points, including five dunks, as the host Wildcats rallied from a six-point second-half deficit to remain undefeated.

Freshman Aaron Gordon finished with 18 points and 11 rebounds for Arizona (15-0, 2-0 Pac-12), which should be No. 1 for a fifth consecutive week when the polls are released on Monday. It was the fifth double-double of the season for Gordon.

C.J. Wilcox led Washington (9-6, 1-1) with 20 points, six rebounds and three assists while Perris Blackwell added 12 points and 12 rebounds. The Huskies fell to 2-28 all-time when facing top-ranked teams.

Washington jumped out to an early five-point lead thanks to back-to-back baskets by Wilcox and didn't trail until Rondae Hollis-Jefferson capped an 8-2 run with a dunk to give the Wildcats a 16-15 lead. Arizona looked like it might pull away as it quickly extended its lead to six points, but the Huskies closed the half with a 12-4 run to take a 35-33 halftime lead as the Wildcats missed their final seven shots from the floor.

The Huskies extended their lead to 42-36 on a 3-point play by Nigel Williams-Goss early in the second half and led 52-51 with 10 minutes to go after a pair of free throws by Blackwell. But back-to-back dunks by Gordon and Johnson keyed a 9-3 run for the Wildcats over the next five minutes, and Washington was unable to regain the lead down the stretch.
