LOS ANGELES — Andre Roberson made the go-ahead layup with 10 seconds remaining, lifting Pac-12 newcomer Colorado to a 63-62 victory over Oregon in the league tournament's quarterfinals Thursday night.
Devoe Joseph, an All-Pac-12 first team selection, missed the potential winning 3-pointer from the left sideline at the buzzer for the Ducks.
Carlon Brown scored 18 points and Roberson added 12 points and 10 rebounds for the sixth-seeded Buffaloes (21-11), who advanced to Friday's semifinals against No. 2 seed California, a 77-71 winner over seventh-seeded Stanford earlier at Staples Center.
The Buffs controlled the paint despite getting outrebounded 43-29 and completed a season sweep of the third-seeded Ducks, who lost 72-71 in the teams' lone regular-season meeting. Colorado notched its second straight 20-win season with a victory over Utah, the league's other new team, on Wednesday.
Tony Woods led the Ducks (22-9) with 14 points. Joseph added 12 while missing all seven of his 3-point attempts, and Carlos Emory had 11 points.
