CORVALLIS, Ore. (AP) -- For an overpowering 12-minute stretch, Stanford played like a team that liked being No. 1 and wants to get that feeling back.

Casey Jacobsen scored 16 points and David Moseley added 15 as the third-ranked Cardinal used a 29-2 run to cruise by Oregon State 73-45 Thursday night.

"Our game plan changes game to game, but the number one thing that the coach puts on the drawing boards at the top is defense," said Jacobsen, who helped Stanford hold the Beavers to 28 percent shooting.

Stanford (13-1, 2-1 Pac-10) started slowly, but began to pull away with a 17-2 run over the final seven minutes of the first half. The Cardinal stepped up the intensity in the first 4½ minutes of the second half with a 12-0 burst to take a 41-18 lead.

The margin of victory was the biggest ever in Corvallis for Stanford, which leads the nation in field goal defense at 32 percent.

"Needless to say, this was a huge win for us," Stanford coach Mike Montgomery said. "This was a game we really needed to have, any way you look at it."

Stanford not only was angry at losing the No. 1 ranking after a 68-65 loss to Arizona last weekend, it was returning to the scene of one of its most bitter disappointments of the 1998-99 season.

The Beavers upset then-No. 6 Stanford 59-45 at Gill Coliseum in the season finale last March 6. The defeat might have cost Stanford a No. 1 seed in the NCAA tournament, and the team wound up being upset by tournament darling Gonzaga in the second round.

Clifton Jones scored 10 points to lead the Beavers (8-5, 0-2), who endured their worst loss since an 87-54 defeat at Stanford on Feb. 13, 1997.

"As the game wears on and you're not making your shots, your defensive energy drops," Oregon State coach Eddie Payne said. "Stanford is a very good team; they withstood our early surge -- the emotion and energy."

Coming off the loss, the Cardinal maybe had too much emotion early in the game, turning the ball over 10 times in the first half. Despite a height disadvantage, the Beavers played tough defense, forcing Stanford into some bad shots.

Stanford trailed 16-12 with 7:20 left in the half before taking control. A 3-pointer by Moseley broke a 16-all tie, and two straight baskets by Jarron Collins made it 24-16. After a dunk by Jones, Moseley scored five straight points to make it 29-18 at halftime.

"I had to come out there and set a precedent for our team, as far as intensity," Moseley said. "I hit a few, and everyone else got confident. It was just rolling from there."

Jacobsen scored seven points during Stanford's 12-0 run to start the second half, but Ryan Mendez topped him. Mendez, scoreless in the first half, hit four straight shots, including consecutive 3-pointers, to make it 58-28.

Stanford's Mark Madsen, in his fifth game back after missing seven weeks with a pulled right hamstring, had eight points and 10 rebounds.

The margin was Stanford's largest ever in 34 games in Corvallis.

Oregon State, second in the Pac-10 in 3-pointers at just over seven per game, finished 3-of-21 from long range.

Brian Jackson, Oregon State's heralded freshman from tiny Knappa, Ore., had a miserable performance in his first big Pac-10 game. He was 2-of-14 from the field and scored seven points, well below his team-leading 16.7 average.

Deaundra Tanner, leading the conference in 3-point shooting at 52 percent, was 0-for-5 and finished with three points.

Beavers center Jason Heide played with his broken right hand wrapped in tape, but it was an injured right ankle that knocked him out of the game. He dived for a loose ball just over three minutes into the game. He returned but was ineffective, and the school said he's doubtful for Saturday's game against California.
