SEATTLE (AP) - Third-ranked Oklahoma made sure Pac-10 officials had no say tonight. OU quarterback Sam 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. Ryan Broyles caught two of Bradford's touchdown throws for OU, which is 3-0 and went home for a bye week feeling much better than it did on its last trip to the West Coast two years ago. Washington fell to 0-3 and was handed its largest margin of defeat at home since 1929, when it lost 48-0 to Southern California. OU scored its most points on the road since a 56-25 win at Texas Tech on Nov. 22, 2003. OU coach Bob Stoops threatened to never again bring his team to Pac-10 country after losing 34-33 at Oregon in 2005, with the help of blown calls at the end. The Pac-10 apologized for errors by its officiating crew after that game, but the conference's system of having its officials work non-conference games at its stadiums still exists.
