The Wildcats trailed by as many as 14, but used a 15-0 run late in the first half to take a brief lead and then outplayed the Huskies in the second half.
Husky freshman big man Spencer Hawes was saddled with foul trouble and could not play in the second half with the same aggressiveness that he showed in the first half.
For the game the Wildcats shot a stellar 65.3% and needed it as the Huskies shot 53.7% themselves.
Seattle native Marcus Williams scored 22 points for the Wildcats, including eight straight at one point. Six of those points came on drives when the sophomore took it right at Hawes in an effort to draw the center's fourth foul.
Quincy Pondexter, the son and nephew of former Lute Olson players at Long Beach State, scored 25 points. He was benched for the first time this season, and used that as motivation.
The Wildcats have won two in a row in Seattle, but have beaten the Huskies just three out of the last nine times they have played.
