SEATTLE, Wash. -- Armed with Sam Bradford's nearly perfect passing, No. 3 Oklahoma made sure Pac-10 officials had no say in this one. Bradford completed 18 of 21 passes for 304 yards, matched his career high with five touchdowns and ran for a sixth score to help the Sooners beat Washington 55-14 on Saturday night. Ryan Broyles caught two of Bradford's touchdown throws for Oklahoma (3-0), which went home for a bye feeling much better than it did on its last trip to the West Coast two years ago. Washington (0-3) felt its largest margin of defeat at home since 1929, when it lost 48-0 to Southern California.
