Arizona (25-3, 14-1 Pac-12) remained on top of the conference standings and won its fourth straight. The Wildcats did it short-handed, with starters Dusan Ristic and Kadeem Allen out because of injuries.
It wasn't easy, as Washington put forth one of its best efforts of the season but still couldn't snap a losing streak that's now reached nine games, tied for the longest in school history. Chance Comanche's rebound and dunk with 52 seconds left finally gave Arizona enough of a cushion to hold on in the final moments.
