LAS VEGAS — Oregon State and Washington played down to the wire twice in the regular season with both teams pulling out wins at home.

So it was no surprise that their Pac-12 men’s basketball tournament first-round game would be similar.

And for the second time they needed overtime to decide a winner.

Like the first meeting, Oregon State came out victorious.

Tres Tinkle hit two free throws with 2.5 seconds left and David Crisp missed a potential game-tying 3 as the No. 10-seeded Beavers escaped with a 69-66 win over the seventh-seeded Huskies on Wednesday night.

The Beavers (16-15) advanced to the quarterfinals for the second time in three years and will play No. 2 seed USC at 6 p.m. Thursday.

“The neat thing was our guys never dropped their chin there,” coach Wayne Tinkle said. “We went with a group there that we were just going to roll with and we made the plays down the stretch. Proud of the guys for the way they hung together.”

The teams split their regular-season meetings with the Beavers winning 97-94 in double overtime at home on Feb.10, then the Huskies won 79-77 at home on March 1.

Drew Eubanks led the way for the Beavers with 19 points Wednesday while Stevie Thompson chipped in 14, Tinkle 12 and Ethan Thompson nine. Tinkle was helped off the court by his teammates after the game.

“I think he tweaked his ankle early in the game and then hurt it a little bit worse later,” coach Tinkle said. “I think the one where he came down on someone else’s foot there on the contact and we went to the free-throw line. He knocked down four after that. Proud of him for that. We’ll see. I haven’t had a chance to talk to him. ... He’s got no choice, he has to play (Thursday). That’s comes from mom not me.”

Matisse Thybulle led Washington with 16 points while Noah Dickerson added 15 and Crisp 13. Dickerson and Jaylen Nowell (nine pints) both fouled out.

Stevie Thompson gave the Beavers an early lead with a 3 in the overtime period but the Huskies scored the next four.

After a Thybulle 3 put Washington up 64-63, the Beavers hit four free throws for a 67-64 lead with 10 seconds left.

Crisp scored on a layup but Tres Tinkle hit two free throws with 2.5 left.

Both teams had a chance win at the end of regulation. Tinkle had an open look for 3 for the Beavers and Zach Reichle’s follow shot was off as the buzzer sounded.

Like the first half, the second half was a nip-and-tuck battle.

The Huskies built a six-point lead to open the half before the Beavers battled back to take a 43-41 lead on Stevie Thompson’s hoop with 12:20 to play.

But the Beavers went 5:40 without scoring and the Huskies took a 47-42 lead. Eubanks’ three-point play ended the drought and pulled OSU within 47-45 with 6:40 to play.

Tinkle’s layup tied the game at 49-all with 5:11 to play.

Eubanks’ alley-oop dunk put the Beavers up 52-51 and Stevie Thompson’s 3 at the top of the key gave OSU its largest lead to that point at 55-51 with 3:32 to play.

Washington used a 7-0 run to take a 12-5 lead with 12:44 to play in the first half.

But the Beavers countered with a 10-2 run, capped off by two Alfred Hollins free throws that gave OSU a 15-14 lead with 7:51 left in the half.

Oregon State took its largest lead of the half at 24-21 on Gligorije Rakocevic’s short jumper with 2:27 left in the half.

However, the Huskies used three-point plays by Sam Timmins and Thybulle and a layup with 1 second left from Crisp to close the half on an 8-1 run for a 29-25 lead.

The Beavers played the final 13:35 of the first half without Ethan Thompson, who was called for a charge, his second foul.

The Huskies also played without a key player as Dickerson was whistled for an offensive foul with 8:28 left in the half and did not return.

The Beavers were just 8 for 23 from the floor and Tinkle had just four shots and scored his only point on a free throw. OSU was 1 for 7 from deep and was 8 for 14 from the free-throw line.

Eubanks led the way with seven points and made all three of his attempts.

The Huskies were 11 for 29 from the floor (2 for 9 from 3) and made 5 of 6 free throws.

Crisp and Thybulle both had eight points to lead Washington in the first 20 minutes.

The Beavers don't have long to celebrate and face a USC team that beat them twice this season.

"We're going to have to some work (mentally)," Wayne Tinkle said. "Some convincing as a staff. Our guys know. This is what its all about, its March Madness, we're not really going to talk about it, just get right back on the horse."
