TEMPE, Ariz. (AP) - Kenjon Barner ran for 143 yards and three touchdowns, Marcus Mariota added 135 yards, and No. 2 Oregon manhandled Arizona State in a 43-21 victory Thursday night.
Facing its first true road test, Oregon (7-0, 4-0 Pac-12) turned what was supposed to be a duel in the desert into another we've-seen-this-before rout by running over the Sun Devils in the first half.
The Ducks had their way against what had been the Pac-12's best defense, racing to a 36-point halftime lead and rushing for 406 yards to win their nation-leading 12th straight road game.
Arizona State (5-2, 3-1) got the start it wanted, forcing a fumble on Oregon's second play and scoring a touchdown on its first.
The Sun Devils wilted after that, unable to make up for the early loss of star defensive tackle Will Sutton or find a way to slow down the Ducks as they raced past.
