Cal (23-7, 13-4) entered the day tied with Washington for the top spot in the league. The Huskies have two games remaining, while the Golden Bears finish the season at Stanford next Sunday.
The Buffaloes (19-9, 11-5) remain in the running to receive one of four automatic byes at the conference tournament. Even more, they kept their flickering hopes afloat for their first league crown since capturing the 1968-69 Big Eight title. Colorado has to win at Oregon and Oregon State -- then receive major help.
Allen Crabbe had 16 points and Justin Cobbs 15 for the Bears, who had their six-game winning streak snapped. They haven't won in Boulder since Dec. 16, 1974.
