EUGENE, Ore. – Kellen Clemens threw for 425 yards and four touchdowns Saturday and No. 20 Oregon beat Washington 45-21, decisively defeating the northwest rival Huskies for the second straight year.

Clemens completed 36 passes, an Autzen Stadium record, with no interceptions as the Ducks handed Washington its 11th consecutive loss against a Pac-10 conference opponent.

Washington (1-5, 0-3) was coming off a bye week after losing 21-17 to UCLA.

The Ducks (6-1, 1-1) defeated Arizona State 31-17 in Tempe last week, a victory that moved Oregon up five spots in the rankings. Oregon’s lone loss this season came against top-ranked USC.

Demetrius Williams had five catches for 92 yards, including a pair of Clemens’ scoring passes.

Isaiah Stanback completed 13-of-26 passes for 111 yards and a pair of touchdowns for Washington. He was intercepted once.

While the Huskies jumped out to an early lead on Stanback’s 26-yard scoring pass to Anthony Russo, Oregon had the next three TDs.

Clemens hit Demetrius Williams with a 1-yard pass, then Jaison Williams from 8 yards out. Oregon made it 21-7 when Demetrius Williams pulled down another pass from Clemens, stumbling into the end zone for a 30-yard reception with two Washington defenders trying to pull him down.

Terrence Whitehead caught an 11-yard scoring pass from Clemens to open the second half, making it 28-7. That pass moved Clemens past Joey Harrington into third on Oregon’s career list with 60 touchdown passes.

Matt Evenson added a 30-yard field goal before freshman Jonathan Stewart’s 17-yard scoring run made it 38-7.

The Huskies showed some life in the fourth quarter.

Stanback found Robert Lewis with a 5-yard touchdown pass with 10:08 to go, and Ty Eriks ran in a 1-yard score some five minutes later to make it 38-21.

The Ducks responded with Brian Paysinger’s 5-yard TD run in the final minutes, and Oregon finished with 570 yards in total offense.

Clemens’ completions broke the Autzen record of 33, shared by Paul Pinegar and Ty Detmer.
