EUGENE - If the Oregon football team needed a spark in Saturday's 115th Civil War, it sure got it early in the second quarter.
The Ducks, who saw their national title aspirations evaporate after last week's loss to USC, jumped out to a quick 7-0 lead, but couldn't get much else going.
Then they were shocked when Oregon State's Jovan Stevenson took a short pass from quarterback Sean Mannion and weaved his way into the end zone for a 58-yard scoring play that got the Beavers even at 7-all.
So what did the ninth-ranked Ducks do?
Just score on three of their next four possessions to take a 28-7 lead into the halftime break and all but make the second half irrelevant.
And they did it in typical Oregon fashion - with speed, big plays and quick drives. And a defense that isn't too shabby, either.
That scoring burst helped the Ducks to their fourth straight victory in the Civil War, a 49-21 win before a crowd of 59,802, the 81st straight sellout of Autzen Stadium.
The win clinched the Pac-12 Conference's North Division title for the Ducks (10-2, 8-1) and a date with UCLA next Friday back in Autzen Stadium for the first Pac-12 title game. The winner advances to the Rose Bowl.
The Beavers (3-9, 3-6) kept it close for a while Saturday, but in the end it was not nearly enough as they head into the offseason with their second straight losing campaign.
"They had a good scheme, but eventually with the ability to throw the ball like Darron (Thomas) threw it today, guys like David Paulson coming up big and catching the ball" that got the Ducks in a groove, Oregon coach Chip Kelly said. "Our plan was to make them defend the whole field and that opens up the run game. Then the run game opens up the throw game and it kind of goes hand in hand."
The Ducks were exceptional in both categories on Saturday. Oregon finished with 365 yards on the ground and 305 through the air for a 670-315 edge in total yards.
After Stevenson's catch and run for the score, the Ducks answered immediately, going 79 yards in nine plays. Thomas found Paulson open for a 16-yard TD. (Time of possession: 3:03).
Next it was a 39-yard run by LaMichael James that set up an 8-yard Thomas to De'Anthony Thomas pass and a 21-7 lead. (Time of possession: 2:55).
Then, right before the half, the Ducks needed only 1:18 to go 75 yards in six plays. Darron Thomas found Kenjon Barner for a 16-yard TD and it was 28-7 at the break.
The Ducks didn't slow down in the second half, scoring on the opening drive of the third quarter. Barner bounced off his own lineman and scored to make it 35-7 just over 2 minutes in.
At that point, it was all over except the final score.
Colt Lyerla made it 42-7 with a 39-yard reception from Darron Thomas early in the fourth and Ayele Forde ran in an 8-yard score later for the Ducks.
Mannion tossed fourth-quarter TDs to Kevin Cummings (19 yards) and Brandin Cooks (23 yards) to complete the Beavers' scoring.
"It comes down to football is a game of making plays and they made more plays than we did," OSU senior linebacker Cameron Collins said. "They got a lot of their guys in space and we weren't able to contain them and that's how it goes."
Oregon had a chance to put the game away much earlier but couldn't take advantage of OSU's slow start.
Oregon's Michael Clay intercepted Mannion on the Beavers' first possession. The Ducks then scored with James breaking a tackle at the 1 and losing his helmet as he bulled his way into the end zone for a 7-0 lead less than three minutes in.
On OSU's next possessions, punter Johnny Hekker had a 10-yard punt and Mannion threw his second interception, this time to Kiko Alonso.
"Turnovers are never good no matter when they are at," OSU senior H-Back Joe Halahuni said. "At the beginning of the game (we wanted) to execute as well as we could and we didn't play to our full potential."
But the Ducks were stopped on fourth down on both possessions, and were stopped on another fourth down the following possession.
That allowed OSU to make it a game as Mannion and Stevenson teamed up for the 58-yard score.
But that was all for the Beavers.
Darron Thomas finished with 305 yards passing, completing 27 of 40 attempts, and four touchdowns. Paulson had a career-high eight catches for 105 yards and James led the rushing attack with 142 yards on 24 carries before leaving after reinjuring his left elbow.
Mannion was 27 of 44 for 299 yards and three scores for the Beavers. But the Beavers managed just 16 net yards rushing.
