EUGENE, Ore. (AP) - Freshman wide receiver James Rodgers ran 25 yards around end for the go-ahead touchdown, and the Oregon State defense stuffed No. 18 Oregon on fourth down to preserve a 38-31 victory in double overtime on Saturday.

The two teams matched field goals in the first extra session before Rodgers broke free on the first play of the second overtime. Oregon (8-4, 5-4 Pac-10) was faced with fourth-and-1 from the 16 when it got a chance to answer, but tailback Jonathan Stewart was stopped for a loss on a run up the middle.

The Beavers (8-4, 6-3) spilled onto the field to celebrate their victory in the 111th Civil War, giving a big lift to their bowl resume with their third straight win. It was the first time a road team had won the rivalry game since 1996.

Both teams had a chance to win in regulation with field goal attempts in the final minutes.

But Oregon cornerback Walter Thurmond blocked a 35-yard field goal attempt by Oregon State's Alexis Serna with 1:09 left to play, and Ducks kicker Matt Evensen missed from 53 yards with 46 seconds on the clock.

Evensen got a second chance after the Beavers were flagged for a personal foul, but this time his 40-yard attempt on the last play of regulation fell short.
