Eugene, Ore. • Marcus Mariota threw a 12-yard touchdown pass to Josh Huff with 29 seconds left, and No. 12 Oregon overcame a tenacious effort by Oregon State 36-35 Friday night in the 117th edition of the Civil War rivalry.
Mariota threw for 285 yards and three touchdowns all to Huff, who had nine catches for a season-high 186 yards and the Ducks (10-2, 7-2 Pac-12) sealed their sixth straight 10-win season. It was also the team's sixth straight victory over the Beavers in the series.
With the Ducks holding a 24-23 lead, the Beavers scored on Sean Mannion's 4-yard pass to Tyler Anderson to pull in front 29-24 early in the fourth quarter. But Oregon answered with Mariota's fourth-and-11 pass to Huff for a 12-yard touchdown and the Ducks took a 30-29 lead with 7:56 left in the game.
Victor Bolden ran for a 25-yard touchdown to make it 35-30 for the Beavers with 1:38 remaining, but Oregon State's defense couldn't stop the Ducks on their final drive.
Mannion passed for 314 yards and two touchdowns for the Beavers (6-6, 4-5), who ended the season on a five-game losing streak, their worst since dropping six straight to conclude the 1997 season.
Freshman Thomas Tyner rushed for 141 yards and another score for Oregon, which finished undefeated at home for the first time since 2010.
The Ducks were coming off a deflating 42-16 loss at Arizona last weekend that ended their Pac-12 and national title hopes.
Oregon State are one of nine Pac-12 teams vying for a spot in the seven conference bowl games. The Ducks were without Byron Marshall, who injured his ankle in the loss to Arizona last week.
Washington 27, Washington State 17 • Bishop Sankey blitzed the Cougars for 139 of his 200 yards rushing in the second half to become Washington's all-time single-season rushing leader, and the Huskies reclaimed the Apple Cup in Seattle.
