TUCSON, Ariz. — Salim Stoudamire took Stanford's success in Tucson personally.

The senior guard had 20 of his 26 points in the second half of No. 14 Arizona's 90-72 victory over Stanford yesterday.

The Cardinal had beaten the Wildcats their past four trips to McKale Center, and won their past three in the series overall.

"I told (Chris) Hernandez I had to get him sometime. It feels great. I want to go out and party," Stoudamire said.

Channing Frye had 15 points and 13 rebounds, Hassan Adams and Chris Rodgers scored 13 each, and Ivan Radenovic had 10 points for the Wildcats.

Frye also tied his season high with four blocks, leading a strong defensive effort that lifted Arizona (9-2 Pac-10, 19-4 overall) to its 16th victory in 18 games. Coach Lute Olson earned his 299th conference victory — second only to John Wooden's 304.

"It was by far the best back-to-back games that we have had all year," Olson said. "I think Stanford had difficulty scoring and getting good looks."

The Wildcats beat California 97-76 on Thursday, coming back strong after a 70-63 loss to Washington State — their first home loss in 18 years to a team with a losing record.

"Right now, we're trying to stay consistent," said Frye, who has scored in double figures 14 consecutive games. "Two games is good. How about three? How about four? I would be fooling myself if I said this was going to make or break our season, but this is a good step forward."

Dan Grunfeld had 23 points for the Cardinal (6-5, 12-9), and Hernandez scored 13.

"The bottom line is they were really, really good," Stanford coach Trent Johnson said. "They had some guys coming out today with a lot of energy. They made some shots early, got some separation and we had to play from behind, which isn't what we do best."

CORVALLIS, Ore. — David Lucas and Nick DeWitz each had 22 points and nine rebounds as the Beavers beat the Ducks, avenging an earlier Civil War loss in Eugene.

Aaron Brooks had 21 points, and Malik Hairston had 20 for the Ducks (3-7 Pac-10, 11-8 overall), who have lost five conference games in a row and sit alone in ninth place.

The Beavers (4-6, 12-9) led 34-30 at the intermission on the strength of DeWitz's 11-point first half.

But Bryce Taylor pulled the Ducks into a tie, first converting a three-point play and then burying a three-pointer to knot the score at 62.

Chris Stephens and David Lucas both made two free throws, and DeWitz hit a three-pointer to give the Beavers a seven-point lead with 1:53 left.

California 84, Arizona St. 82

TEMPE, Ariz. — Richard Midgley's off-balance layup with 2.8 seconds left lifted the Bears over the Sun Devils.

Arizona State (5-6, 16-7) called a timeout with 2.2 seconds left, and Ike Diogu missed a 12-footer on the baseline as time expired. Diogu had 35 points and seven rebounds.

Rod Benson led California (5-6, 12-9) in scoring with 20 points, and Midgley added 15 points.
