Bryce Alford scored nine points on 3-of-5 shooting from 3-point distance and Norman Powell finished with eight points for the Bruins, who missed a chance to stay within a game of first-place Arizona.

The Bruins had a chance to take the lead with 14 seconds left, but Jordan Adams was called for a charge on Brandt and Nelson made two free throws on the other end to push the led to three. Anderson was fouled intentionally with 5.6 seconds left, missed the first free throw and made the second and Cooke sealed the win with two free throws on the other end.

Adams, who came in averaging a team-high 17.3 points, missed all seven of his field goal attempts in the first half but the Bruins still managed to take a 31-29 lead into the break. Oregon State twice went up by six early in the second half, but UCLA answered back with a 15-4 run that gave the Bruins their biggest lead of the second half at 52-47 with just over eight minutes left.
