NORMAN, Okla. - Jason White threw for two touchdowns and ran for another and Oklahoma's defense was dominant in leading the top-ranked Sooners to a 52-9 rout of Oklahoma State on Saturday.

In ending a two-game losing streak against the Cowboys, Oklahoma (9-0, 5-0 Big 12) remained on track for the Big 12 title and a spot in the BCS' national title game.

DeJuan Jones added two touchdowns for the Sooners.

"This was one of those hurdles we knew we had to get over," Jones said. "We came out fired up and knew we had to take care of business today."

The defeat dropped the Cowboys (7-2, 3-2 Big 12) a game behind Texas and into third place in the Big 12 South, all but ending their hopes of a BCS game.

The momentum of the game shifted late in the first quarter on Darrent Williams' fumble of a punt return. Williams fielded the ball, dropped it, then tried to pick it up again. The ball squirted away and Oklahoma recovered it at the 50.

Eight plays later, Jones scored from 3 yards out to give the Sooners a 17-0 lead early in the second quarter.

"They are an awfully good football team; we knew that coming in," Cowboys coach Les Miles said. "We didn't get exactly what we wanted from our football team, but they certainly did."

In a game that featured two of the nation's top scoring offenses, it was Oklahoma's defense that stole the show.

Oklahoma State's celebrated trio of quarterback Josh Fields, running back Tatum Bell and receiver Rashaun Woods couldn't do much against the Sooners when the game was competitive.

"All week the whole talk was about their offense," Sooners. coach Bob Stoops said. "You would have never thought we played any defense around here."

The Cowboys had more punts (5) than first downs (3) in the first half, and had more penalty yards (58) than offensive yards (47) late into the third quarter.

In the Sooners' final show of superiority, Oklahoma State failed to punch the ball into the end zone on three tries from the 1 early in the fourth quarter.

The Cowboys, who came into the game averaging 445 yards of offense a game, were held to a season-low 161 yards.

Renaldo Works led the Sooners with 103 yards rushing on 19 carries.

The Sooners own the nation's longest winning streak at 11 games.
