Matthew Bryan-Amaning helped Washington run past Oregon State.

He knows it was all because of the Huskies' defense.

Bryan-Amaning had 24 points and a career-high 15 rebounds and No. 23 Washington beat Oregon State 103-72 Saturday.

"Everyone looks at the way we have been scoring, and that's because we run," Bryan-Amaning said. "But the only reason we run is we get stops. Contest the shot, rebound and push it."

Jared Cunningham led Oregon State (7-8, 2-2) with 21 points. Roberto Nelson had 15 points.

Washington (12-3) is 4-0 in the Pac-10 for the first time since winning its first six in 1984.

The Beavers led 37-28 in the first half, but Washington closed out the half with a 12-2 run.

Venoy Overton hit a runner as time expired to give the Washington the lead. The Huskies still have not trailed at halftime this season.

"For him to go around about 10 dudes and make that floater, it was a momentum change," Washington's Isaiah Thomas said. "We took that into the second half.

"We're the kind of team and when we're down, we think we're going to come back," he added. "We feel like we can come back on any deficit."

The Huskies kept it up after halftime, opening with a 16-2 run before Beavers coach Craig Robinson called a timeout to regroup with 16:05 left. Bryan-Amaning had eight points during the surge.

"I called timeouts, when I thought I should of but I don't think that is going to stop these guys," Robinson said. "You have to defend these guys and play tough the entire game or a tie game will turn into a blowout in five minutes."

Washington shot 64 percent in the second half, scoring 75 points over the last 23:25 for its 11th straight win over Pac-10 opponents.

That streak is the Huskies' longest since the Pac-10 was formed in 1978.

"We took a huge shot from Oregon State in the first half," Washington coach Lorenzo Romar said. "They came out very aggressive, very physical, scrappy. They came ready to play."

Thomas added 19 points and had eight assists for Washington. Scott Suggs finished with 12 points.

The Huskies blocked 10 shots and had nine steals. They entered the game with a nation-leading 8.3 steals per game.

"That was turnovers, offensive rebounds by them, and they are a momentum team so once they get going, it was like we were a completely different team," Robinson said.
