Solomon Hill had 19 points, Mark Lyons added 14 and No. 12 Arizona pulled away after an uninspired start to beat Washington 70-52 Wednesday night.
Whether it was the late tipoff or the rare snowstorm outside, Arizona (22-4, 10-4 Pac-12) was sluggish at the start, needing nearly 12 minutes just to crack double figures. Once they got rolling, the Wildcats didn't stop, revving up the rowdy crowd inside McKale Center with fastbreak layups and tenacious defense.
Nick Johnson added 12 points, five assists and keyed a second-half run that put the game out of reach.
