Oklahoma 31,

Kansas State 21

-- Jason White spent much of the week touting a young Oklahoma teammate for the Heisman Trophy.

On Saturday, he played -- with one exception -- like a front-runner for a second straight award of his own.

White threw a third-quarter interception that was returned by Kansas State for a touchdown and a Wildcats lead. But he rebounded to toss two clutch touchdown passes to Mark Clayton -- part of a four-touchdown day for White -- lifting No. 2 Oklahoma to a 31-21 victory.

"I knew I made a mistake but you wanted to make up for it," said White, who also threw two touchdown passes to Travis Wilson in the first half. "The pass game was there all day, and we had to take advantage of it."

Freshman Adrian Peterson added 130 yards rushing -- all but 26 of those after halftime -- and helped the Sooners (6-0, 3-0 Big 12) control the tempo in the fourth quarter. White is among those campaigning for Peterson to get Heisman consideration.

Kansas State, which beat Oklahoma 35-7 for the Big 12 title a year ago, led three times Saturday but dropped to 2-4 overall and 0-3 in conference play for the first time since 2001.

"I had to be real patient," said Peterson, the only Oklahoma freshman to go over 100 yards in each of his first six games. "The guys kept me going and told me that it would open up."

Running back Darren Sproles was held largely in check both by Oklahoma's defense and Kansas State's pass-first game plan.

Sproles, who ran for 235 yards in the Big 12 title game last year, had 34 yards on only 13 carries. One of those carries was a botched halfback pass attempt in the first quarter, one snap before a turnover that slowed the Wildcats' early momentum.

Kansas State's Jesse Tetuan (23) doesn't have quite as much to celebrate as Oklahoma's Wes Sims (60) and Jason White, who went 20 of 31 for 256 yards, 4 TDs.
