Las Vegas • Drew Eubanks scored 19 points, Stephen Thompson Jr. added 14 and Oregon State outlasted Washington 69-66 in overtime on Wednesday night in the opening round of the Pac-12 tournament.

Oregon State went up 66-64 in overtime on Tres Tinkle’s two free throws and Washington tried to set up a shot to tie, but David Crisp threw the ball out of bounds. Eubanks hit 1 of 2 free throws and Crisp scored on a layup with 3.1 seconds left to pull the Huskies within two.

Tinkle hit two more free throws with 2.5 seconds left and Crisp got a good look at a tying 3-pointer, but it caromed off the back of the rim.

Oregon State (16-15) moves on to face No. 2 seed Southern California in the quarterfinals on Thursday.

Matisse Thybulle had 19 points and Noah Dickerson 15 points as Washington (20-12) saw its slim NCAA Tournament hopes disappear.

Washington made a strong NCAA Tournament push with consecutive wins over Arizona and Arizona State in early February. But the Huskies fell away from the NCAA bubble with a stretch of four losses in five games, including a double-overtime setback at Oregon State.

Washington won two of its final three games, but needed a strong run in the Pac-12 tournament to have any NCAA shot.

Colorado 97, Arizona St. 85 • McKinley Wright IV had 20 points and 11 assists, and Colorado put a dent in Arizona State’s NCAA Tournament hopes.

Colorado (17-14) made 13 of 21 from 3-point range and took control of a close game with a 15-1 run midway through the second half.

The Buffaloes shot 54 percent overall and made 18 of 20 free throws to earn a spot in Thursday’s quarterfinals against No. 15 Arizona.

Wright also had eight rebounds and Dominque Collier had 17 points for Colorado.

Arizona State (20-11) had a pair of long stretches without a field goal in the second half and went 12 for 21 from the free throw line to lose a game it needed to win. Remy Martin had 20 points to lead the Sun Devils, who may have an anxious Selection Sunday after being ousted so early in the Pac-12 tournament.

Stanford 76, California 58 • Reid Travis had 19 points and 13 rebounds, helping Stanford roll over rival California.

Stanford (18-14) shot well early to build a double-digit lead and shut the Bears down defensively to earn a spot in Thursday’s quarterfinals against fourth-seeded UCLA.

The fifth-seeded Cardinal held Cal to 28 percent shooting and had a 30-18 advantage in the paint. Travis hit 7 of 11 shots and Dorian Pickens scored 16 points.

No. 12 seed Cal (8-24) closed out a difficult first season under Wyking Jones with its seventh straight loss and 16th in 17 games.
