EUGENE, Ore. -- Arielle Roberson scored 16 points to lead No. 19 Colorado to a 60-49 victory over Oregon Friday night.
Chucky Jeffery added 12 points and 10 rebounds for the Buffaloes (23-5, 12-5 Pac-12), who won their eighth in a row to clinch a bye in next week's conference tournament.
Colorado is a game ahead of Washington for fourth place in the Pac-12, but the Buffaloes own the tiebreaker because they won the head-to-head matchup with the Huskies last weekend in Boulder, Colo. Colorado's last regular-season game is Sunday at Oregon State.
Roberson's three-point play with 43 seconds left in the half gave the Buffaloes a 24-21 lead. The Buffs led 30-29 with 12 minutes to play, and outscored the Ducks 14-3 over the next four minutes to build a 12-point lead.
Liz Brenner led Oregon (4-25, 2-15) with 12 points. Jillian Alleyne had 10 points and 12 rebounds for the Ducks.
