CORVALLIS, Ore. (AP) Ahmad Starks had all 18 of his points during an electrifying second half performance to lead Oregon State to an 83-69 win over Colorado Saturday, helping the Beavers clinch only their second winning season in 22 years.

Roberto Nelson added 16 points and Jared Cunningham had 15 for the Beavers (17-13, 7-11 Pac-12), in the final game of the regular season for both teams. Oregon State will be seeded either eighth or ninth in the Pac-12 tournament.

Askia Booker had 15 points and Andre Roberson added 14 points and nine rebounds for the Buffaloes, whose hopes for the fourth seed and corresponding first-round bye were dashed. The Buffs (19-11, 11-7) need one more win to achieve back-to-back 20-win seasons for the first time in school history.

Starks, a point guard, scored 11 straight points during a stretch early in the second half.
