No. 3 Oregon 49, No. 22 Arizona 0
Redshirt freshman Marcus Mariota threw for 260 yards and two touchdowns, including a 55-yard scoring pass to freshman Bralon Addison late in the third quarter, and Oregon rolled. Billed as an offensive juggernaut between the Pac-12's fastest scoring teams, Oregon didn't find its stride until the second half - and Arizona never did - and the Ducks (4-0, 1-0) got their seventh straight conference-opening victory.
