PASADENA, Calif. — Backup Matt Scott had another big game, passing for a career-high 319 yards, and No. 15 Arizona held off UCLA 29-21 on Saturday to remain in contention for its first Pac-10 championship.

Scott was 24 of 36 with one interception and one touchdown. The junior also carried 12 times for 71 yards.

Scott threw for 233 yards and ran for another 65 in a 44-14 victory over Washington last weekend filling in for Nick Foles, who sprained his right knee two weeks ago. Foles might be healthy enough to return next Saturday when the Wildcats play at No. 13 Stanford.

Keola Antolin rushed for 111 yards on 23 carries for the Wildcats (7-1, 4-1 Pac-10).

No. 13 Stanford 41, Washington 0

At Seattle, Andrew Luck ran for one score and threw for another, and No. 13 Stanford scored touchdowns on its first four possessions in an impressive rout of Washington.

Facing Washington quarterback Jake Locker in a matchup of touted NFL draft prospects, Luck was easily more impressive. The Stanford sophomore completed 19 of 26 passes for 192 yards and added another 92 yards rushing. Stepfan Taylor ran for 97 yards and two touchdowns for Stanford (7-1, 4-1 Pac-10).

Arizona State 42, Washington State 0

At Tempe, Ariz., Steven Threet returned from last week's concussion to throw for 300 yards and hit Jamal Miles on two of his three touchdown passes, helping Arizona State extend Washington State's Pac-10 losing streak to 15 games with a dominating win.

Coming off an embarrassing loss to California, Arizona State (4-4, 2-3) never gave Washington State (1-8, 0-6) a chance at the upset, overwhelming the Cougars with its rapid-fire offense.
