No. 7 UCLA 81, No. 24 Arizona 66

Had this game been played a month earlier, it would have been the worst home loss in coach Lute Olson's 24-year career at Arizona. Instead, a 92-64 loss to North Carolina last month holds that distinction.

Josh Shipp tied a career-high with 24 points (on 10-of-14 shooting), and Darren Collison added 17 points and a career-high 15 assists as the seventh-ranked Bruins beat No. 24 Arizona 81-66 in Tucson, Ariz., on Saturday.

On senior night for the Wildcats, UCLA (23-3 overall, 12-2 Pac-10) defeated Arizona for the fifth-straight time. It was the seventh loss in 11 games for Arizona.

Arizona (17-9 overall, 8-7 Pac-10) fell to 4-14 against ranked opponents in the past two years and is flirting with missing the NCAA Tournament for the first time in 23 years.

Marcus Williams and Mustafa Shakur led the Wildcats with 17 points each.

UCLA will now host the Bay area schools this week; Arizona will begin a three-game road trip with a visit to ASU on Sunday.

Arizona State 68, No. 23 USC 58

Rest assured Sun Devil fans, your team is no longer on its way to the first winless conference record since the Pac-10 expanded to 10 teams in the 1978-79 season.

Jeff Pendergraph had 14 points and 15 rebounds to lead ASU to a 68-58 win over No. 23 USC in Tempe, Ariz., on Sunday. The Sun Devil faithful stormed the court after ASU's first conference win — a victory that ended the team's school record 15-game losing steak.

"A lot lesser group of fans could have been at home watching Desperate Housewives," ASU coach Herb Sendek told the Associated Press.

Arizona State (7-19 overall, 1-14 Pac-10) hadn't won a game since Dec. 21, against North Carolina A&T. The losses certainly weren't from lack of effort; ASU's past five defeats had come by six points or fewer.

Gabe Pruitt scored a game-high 22 points for USC (19-8 overall, 9-5 Pac-10), while Lodrick Stewart added 18.

ASU will seek its second-straight conference win at home against Arizona on Sunday; USC remains tied for third in the Pac-10 and will host Stanford and Cal this week.

Stanford 88, No. 17 Oregon 69

Without its second-leading scorer and few believers outside of Northern California, Stanford simply finished its 14th-straight home sweep of the Oregon schools.

Brook Lopez finished with a career-high 26 points, leading the Cardinal to its fifth win over a ranked opponent this season and an 88-69 win over No. 17 Oregon in Maples Pavilion on Saturday.

It was Stanford's 21st consecutive win at home over the Ducks.

Oregon (20-7 overall, 8-7 Pac-10) was led by the 25 points of senior guard Aaron Brooks, while freshman Tajuan Porter had 20. The Ducks have lost six of their past eight, but will finish the regular season with three home games.

Seattle product Mitch Johnson replaced Stanford's Anthony Goods — who was out with a sprained ankle — in the starting lineup, and finished with a career-high 12 points and no turnovers.

Oregon will host the Washington schools this week; Stanford (17-8 overall, 9-5 Pac-10) will travel to the L.A. schools.

Cal 84, Oregon State 80 (OT)

Cal apparently had too much of a home court advantage against Oregon State on Saturday.

Down 71-68 in regulation, the Beavers' game-tying attempt was blocked and the final buzzer sounded. After further inspection, officials determined that the clock operator started the time too early.

OSU's Angelo Tsagarakis took advantage of the second opportunity, sending the game into overtime with a last-second 3-pointer. In the extra period, Cal scored the first six points and never looked back en route to an 84-80 win in Berkeley, Calif.

Patrick Christopher led the Golden Bears (14-12 overall, 6-8 Pac-10) with a career-high 24 points off the bench. Ayinde Ubaka and Theo Robertson each had 21.

Reserve Jack McGillis had 24 points to lead the Beavers (10-18 overall, 2-13 Pac-10).

Cal will visit No. 4 UCLA on Thursday; OSU will host Washington.
