EUGENE, Ore. (AP) -- There were no fancy plays or controversies in Oregon's victory over UCLA, only workmanlike efficiency.

The No. 18 Ducks, who were humbled at California last weekend, put together a solid 30-20 win over the Bruins on Saturday.

Dennis Dixon threw two touchdown passe and Jonthan Stewart ran for 121 yards for Oregon (5-1, 3-1 Pac-10). Brian Paysinger had four catches for 105 yards and a TD.

"I think what we wanted to establish was our regular game plan that we've had for the whole season," Stewart said.

Going into the game, UCLA (4-2, 2-2) led the Pac-10 and was ranked second nationally in run defense, allowing 50 yards a game. Ducks ran for 256.

"We usually have stopped the run, and we did not do that today," UCLA coach Karl Dorrell said. "When you get an offense running and passing like that it makes it a lot harder for your defense to attack."

The Ducks were coming off a 45-24 loss at California, when their running game -- and just about everything else -- malfunctioned. It was the Ducks' first loss of the season and put them in a four-way tie for third in the Pac-10. UCLA, coming off a victory over Arizona, was also in that group.

Patrick Cowan started at quarterback for the Bruins in place of Ben Olson, who injured his knee during last weekend's victory over Arizona and was expected to be out up to six weeks.

Cowan, a 6-foot-5, 225-pound sophomore, completed 16 of 31 passes for 112 yards. He was intercepted once -- and lost his voice.

"I felt I could have done some things better," Cowan said. "I knew they had a good D-line, and they got some pressure on us."

Kahlil Bell had two short TD runs for UCLA.

Oregon was fast and efficient on its first drive, scoring on an 11-yard pass from Dixon to Dante Rosario. The point-after was blocked by UCLA's Justin Hickman, making it 6-0.

Jeremiah Johnson added a 7-yard touchdown run for the Ducks, before the Bruins made it 13-3 with Justin Medlock's 35-yard field goal.

Before the end of the first quarter, Paysinger outsprinted Bruins free safety Dennis Keyes and caught Dixon's 26-yard pass in the end zone to make it 20-3.

"We wanted to make a statement early. Coach said to get after it, get a push and get 'em down," Oregon center Enoka Lucas said. "The more we beat them down the more they gave up."

Medlock had a 48-yard field goal before the half to narrow it to 20-6.

James Finley caught a 4-yard TD toss from Oregon backup Brady Leaf in the second half after Dixon was hit hard earlier in the series. It was Leaf's only completion of the game.

Dixon was 10-for-17 for 144 yards and no interceptions.

Bell's 1-yard scoring run to open the final quarter narrowed it to 27-13.

Matt Evenson attempted a 45-yard field goal for the Ducks which fell way short, but he later made a 21-yarder that put the Ducks ahead 30-13. Bell scored on another 1-yard dash with 1:59 left in the game.

Stewart credited the offensive line for Oregon's success.

"Our blocking was really good," he said. "There were holes we could actually choose from."

UCLA tight end Ryan Moya left the game in the first half. The team reported he had a fractured left fibula, but no additional details were immediately available. Offensive tackle Aleksey Lanis also left the game with an ankle injury.

Oregon guard Josh Tschirgi left the game with a sprained ankle.

The teams hadn't met since 2004, when UCLA won 34-26 in Autzen Stadium.

UCLA plays next week at Notre Dame, while Oregon heads to Washington State.

"Getting back home after a couple of road games, and a tough loss last weekend, we wanted to come out and set the tone," Oregon linebacker Blair Phillips said. "I think we did that for the most part in the first quarter."
