Santa Clara, CA - Oregon wasn't going to let Arizona ruin its national title dreams for a second straight season.

The Ducks were 9-1 going into last year's meeting in Arizona, which the Wildcats won 42-16. Oregon followed that up with a 31-24 home loss to a then- unranked Arizona squad back in October.

Since then, the third-ranked Ducks have won eight straight games, including a 51-13 rout of the eighth-ranked Wildcats in the Pac-12 championship game at Levi's Stadium.

Marcus Mariota, the front-runner for the Heisman Trophy, accounted for five touchdowns on Friday and the Ducks assuredly locked up a spot in the first College Football Playoff. Oregon (12-1, 8-1 Pac-12) entered the game No. 2 in the CFP rankings.

Mariota completed 25-of-38 passes for 303 yards and two touchdowns for the Ducks, who racked up 640 yards of total offense. The mobile junior from Hawaii has thrown for at least one touchdown in each of the first 39 games he's played at Oregon, an FBS record.

Mariota also carried the ball 10 times for 33 yards and three scores for Oregon, which captured its second Pac-12 title. Royce Freeman rushed for 137 yards on 21 carries and Darren Carrington caught seven passes for 126 yards and a touchdown.

Anu Solomon completed 6-of-12 passes for 34 yards for the Wildcats (10-3, 7-2), who entered the contest No. 7 in the CFP rankings. Jesse Scroggins started the second half and connected on 3-of-9 passes for 79 yards, one touchdown and an interception.
