Washington guard Andrew Andrews hit a jump shot with less than one second remaining to beat Colorado on Thursday night.
Andrews pulled up in front of the free throw line and released the ball as Buffaloes forward Wesley Gordon tried to contest.
Andrews, a junior, finished with 12 points, seven rebounds and three assists.
His shot gave the Huskies' their third consecutive victory, a stretch that followed a four-game losing streak.
The win improved the Huskies to 14-4 (3-3 Pac 12) and dropped Colorado to 9-9 (2-4 Pac 12).
Washington will play at No. 12 Utah on Sunday.
