CORVALLIS - Oregon picked an optimal time to produce one of its best offensive games of the season.

The Ducks continued where they left off two weeks earlier against Arizona, putting up a school-record 694 total yards - including 385 yards rushing - on a solid Oregon State defense in a 65-38 win at Reser Stadium.

"I was pleased that against a good rushing defense that we were able to do that," Oregon coach Mike Bellotti said.

Oregon had little trouble moving the ball against the Beavers, who entered the game second in the Pacific-10 Conference in total defense, second against the run and fourth versus the pass.

Oregon nearly reached its per-game rushing average of 268 by halftime with 252, as the Ducks took a 37-17 lead.

Jeremiah Johnson accounted for 203 of that by himself, on 12 carries with one touchdown.

Quarterback Jeremiah Masoli put together one of his most complete games in his nine starts.

The two-time Pac-10 offensive player of the week threw for 274 yards and three touchdowns with no interceptions. He also rushed for 53 yards and one score.

Masoli said he feels like he's gaining a grasp of the Oregon spread offense.

"There's a lot of responsibility on the quarterback, and I think I'm getting it now," he said.

Oregon put up 37 points by halftime despite often starting with poor field position.

The Ducks scored 27 of those points on five drives that they started at their own 20 or worse.

Oregon State made the game interesting with a third-quarter touchdown to cut the Ducks' advantage to 37-24.

But Oregon answered with what had helped the Ducks build a first-half lead - the running game. Oregon moved the ball 76 yards in five running plays, capping the drive with a 14-yard Masoli touchdown.

As has been the case in several games this season, the Oregon defense gave up big plays but did just enough to give the offense some breathing room.

A 40-yard interception return for a touchdown by Walter Thurmond III gave the Ducks a 37-10 lead.

The Beavers had trouble running the ball as Oregon took advantage of the absence of Oregon State freshman running back Jacquizz Rodgers, who was out with a shoulder injury.

The Ducks keyed on the run, allowing Oregon State just 41 yards on 16 carries in the first half and 89 yards on 31 carries for the game.

Oregon kept a close eye on Jacquizz's brother, sophomore receiver James Rodgers, when he got the ball.

Rodgers came up big for the Beavers in the 2007 Civil War, including scoring the game-winning touchdown on a 25-yard fly sweep in a 38-31 victory.

Saturday, he had 29 yards on six carries in the first half and 56 yards on seven tries for the game.
