Andre Roberson scored a career-high 24 points and helped spark an 18-2 second-half run to help Colorado beat Stanford 65-63 on Wednesday night.
Roberson, the leading rebounder in the country going into the night, had eight boards and finished 9 of 13 from the floor while helping the Buffaloes (19-8, 9-6 Pac-12) complete a season sweep of the Cardinal after five straight losses in the series between the two schools.
Andy Brown matched his career high with 17 points while Dwight Powell added 12 for Stanford (16-13, 7-9).
Powell nearly pushed the game into overtime after driving around Roberson and dunking the ball on the game's final play, but officials reviewed television replays and ruled that time expired before Powell's bucket.
Colorado has won eight of 10 since opening conference play 1-4 but remains in a logjam in the middle of the conference standings.
