NEW ORLEANS (AP) -- Baker Mayfield passed for 296 yards and two touchdowns, including one scoring pass to fellow Heisman Trophy finalist Dede Westbrook, and seventh-ranked Oklahoma ended its season on a 10-game winning streak, defeating No. 17 Auburn 35-19 in the Sugar Bowl on Monday night.
Sooners running back Joe Mixon's two short touchdown runs were among the highlights of a performance in which he gained 180 yards from scrimmage -- 91 rushing on 19 carries and 89 receiving on five catches.
Auburn (8-5), which wound up in the Sugar Bowl despite dropping its last two Southeastern Conference games to Georgia and Alabama, entered the game hopeful that it would be buoyed by the return of quarterback Sean White, who'd missed the Tigers' final two games with a throwing shoulder injury. White led Auburn to a touchdown on its first series -- Chandler Cox's 3-yard run on fourth down -- but the quarterback left the game for good in the first half with a right arm injury.
With John Franklin and Jeremy Johnson taking the remainder of the snaps, the Tigers' offense was less consistent, increasing pressure on Auburn's 20th-ranked defense to keep the Sooners' fast-paced, high-powered attack in check.
That was bound to be a struggle.
Mixon broke loose for a 35-yard run in the third quarter that set up his second TD, which he scored from 4 yards out by diving for the pylon. Early in the fourth quarter, Samaje Perine took a direct snap for a 2-yard TD that made it 35-13.
With the Sooners (11-2) pulling away for their second Sugar Bowl triumph in four years, Auburn fans started filing out.
With back-to-back fourth-quarter runs of 16 and 15 yards, Perine reached the 83-yard mark, giving him the Oklahoma record for career yards rushing with 4,119. He added 3 more yards afterward to reach 4,122. The previous record of 4,118 was set by Billy Sims back in 1979. When Perine set the mark, Mixon quickly trotted toward him for a congratulatory embrace on the field.
