PACIFIC 10 BASKETBALL ROUNDUP : Arizona State’s Riley Sinks Arizona, 53-52

Ron Riley pulled up in the lane for a 13-foot jump shot for the game’s final points with 1:34 to play Thursday, and No. 15 Arizona State hung on to defeat No. 9 Arizona, 53-52, in the Pacific 10 opener for both teams at Tempe.

It was the first time in 20 years that both had been ranked when they played each other.

Arizona State (10-2) had lost 14 of its last 16 against the Wildcats (9-3), but had beaten Arizona twice in three seasons in Tempe. The Sun Devils got 19 points from Riley--16 in the second half--and 12 from Isaac Burton to make it three of four, even though Mario Bennett was held to eight points.

Arizona’s Ben Davis scored 15 points and Ray Owes had 11.

The last time both teams were ranked in the top 15 when they met was Feb. 1, 1975.

Washington State 83, No. 17 California 71--Donminic Ellison scored a career-high 26 points, and the Cougars pulled away down the stretch to beat the Bears at Pullman, Wash.

Washington State improved t 5-3; Cal lost its second consecutive game after beginning the season 7-0.

Carlos Daniel added 13 points for Washington State, which outscored Cal, 17-7, in the final two minutes of the game.

No. 23 Stanford 65, Washington 51--Brevin Knight, whose status was in doubt because of an injury, scored 10 of his 16 points in the second half at Seattle as the Cardinal became 10-0 for the first time since 1953.

David Harbour scored 14 points for Stanford.

Knight, a sophomore point guard, was found to have a stress reaction in his leg. His status for the conference opener was in doubt as he waited for medical clearance.

Harbour scored five points and Andy Poppink four during a 10-0 run early in the second half that put the Cardinal up, 44-29.

The Huskies (4-5) could get no closer than nine points.

Mike Amos scored 13 points for Washington, which shot only 33% and was outrebounded, 38-29.
