AUSTIN, Texas — Ramon Richards intercepted Sam Ehlinger's pass in the end zone in overtime and Matt Ammendola kicked a field goal, giving No. 10 Oklahoma State a 13-10 victory over Texas on Saturday.
The Cowboys (6-1, 3-1 Big 12) scored the winning points on a 34-yard field goal by Ammendola on the first possession of OT. He missed a 29-yard attempt in the fourth quarter.
Though the field goal came first, Richards didn't realize the game ended with his play.
Texas (3-4, 2-2) had a first down on the Oklahoma State 12 after a pass interference penalty against A.J. Green.
Oklahoma State's Masons Rudolph passed for 282 yards. The Cowboys beat Texas for the fifth straight time in Austin, the most ever by a Longhorns opponent.
