EL PASO, Texas — If anyone forgot how good Oregon looked earlier this season, Jonathan Stewart and Justin Roper offered a reminder.

Stewart set a Sun Bowl record with a career-high 253 yards rushing, while Roper, a redshirt freshman, threw four touchdown passes in his first start to help Oregon beat South Florida, 56-21, yesterday.

"I knew I was ready to play," Stewart said. "I knew I was ready to run today. I think I played well, but I'll give all the credit to the offensive line for opening up the truck lanes."

The Ducks (9-4) scored 28 straight points in the third quarter to snap a four-game postseason losing streak, their first bowl win since beating Colorado, 38-16, in the Fiesta Bowl after the 2001 season.

Oregon made it look easy against South Florida (9-4), which boasted one of the nation's better defenses.

"I didn't expect to have that many stats. I expected to do well, but not that well," said Roper, who completed 17 of 30 attempts for 180 yards with no interceptions. He tied a Sun Bowl record with the four TD passes.

The Ducks also won for the first time since losing quarterback Dennis Dixon to a knee injury in November, snapping a three-game losing streak that killed their national title hopes.

"Losing a Heisman Trophy candidate — the leading Heisman Trophy candidate — was a big blow," Oregon coach Mike Bellotti said. "It took us a couple of games to recover."

How easy was it this time for the Ducks? They won a matchup of teams that had been ranked No. 2 in the nation earlier this season handily, despite setting a Sun Bowl record with 138 penalty yards.

Roper started the second-half scoring avalanche with a 14-yard TD strike to Jaison Williams and added a 15-yard scoring pass to Ed Dickson.

On the next play from scrimmage, Walter Thurmond stepped in front of a pass by South Florida's Matt Grothe and returned it 25 yards for another TD, giving the Ducks a 39-14 lead midway through the third.

"Second half, I can't explain what happened," Bulls coach Jim Leavitt said. "We didn't play good enough defense. That's all there is to it, and when you have those turnovers you have no shot at all."

Grothe had another interception on the ensuing possession, setting up Roper's 8-yard TD pass to Stewart.
