David Singleton hit consecutive 3-pointers early in the second half to help UCLA extend a slim advantage, and the 23rd-ranked Bruins rode it to a hard-earned 57-52 Pac-12 win Saturday over Oregon State in Westwood, Calif.

Cody Riley scored a team-high 16 points as the Bruins (13-3, 9-1 Pac-12), playing for the first time in a week, managed to pull out a win despite their lowest point total of the season.

The 52 points allowed matched the fewest given up by UCLA this season, equaling the mark set in a nonconference win over Seattle on Dec. 3.

Ethan Thompson led Oregon State (8-7, 4-5) with a game-high tying 16 points.

UCLA led by as many as seven in the first half before taking a 27-25 advantage into the break.

After a free throw by Riley to open the second period, Singleton bombed in his 3-pointers -- sandwiching two free throws by Thompson -- to increase the Bruins' lead to 34-27.

The Beavers were down 52-41 with 3:50 remaining before making a late run. Warith Alatishe had two free throws and a dunk in an eight-point burst that made it a three-point game with still 1:45 to play.

After Riley and Thompson exchanged a single free throw apiece, Oregon State had a chance to tie in the final seconds. But after a timeout, the Bruins forced Thompson into a turnover, then iced the win with four free throws from Tyger Campbell.

Riley completed a double-double with a game-high 10 rebounds for UCLA, which had won seven in a row before losing 73-72 at Stanford in overtime on Jan. 23. The Bruins had a home game Thursday against No. 21 Oregon postponed.

Singleton finished with nine points, all on 3-pointers, while Jaime Jaquez Jr. also had nine points to complement eight rebounds. Campbell was a third Bruin with nine points.

The 57 points were one fewer than the Bruins scored in their season-opening loss at San Diego State.

Maurice Calloo backed Thompson with nine points for Oregon State. Alatishe gathered a team-high nine rebounds to go with six points.
