Oklahoma State ended the game with 282 yards passing and 146 yards rushing.
This was the third time Oklahoma State had played an overtime game this season, and it was also the latest instance of a rebuilding Texas team showing it can hang with the top opponents on its schedule. Last week the Longhorns overcame a 20-point deficit to take a 24-23 lead on Oklahoma before dropping the game 29-24.
On Saturday, the Cowboys leaned on their defense.
The Cowboys (6-1, 3-1 Big 12) entered the game as the top offensive team in the nation, averaging nearly 611 yards and 49 points per outing, but they were stymied by the improving Texas defense.
Sitting at 3-3 overall and 2-1 in conference, Texas has a shot to stay in contention for the Big 12 title with an upset at home.
A fumbled by running back Justice Hill at the UT 14 early in the second quarter denied the Cowboys another scoring chance; Texas quickly took advantage.
The interception came on third down with the Longhorns a short distance away from a shot at a game-tying field goal try to force a second overtime.
NOTES: Texas' youth has shined through in the starting lineup. Oklahoma State has won two straight against the Mountaineers.
Texas will presumably improve quickly under Herman and be competing for Big 12 championships soon enough, but the deflating losses have to be weighing on the Longhorns at this point.
Two plays later, freshman quarterback Sam Ehlinger hit junior wide receiver John Burt on a simple hitch route that should't have gone for more than 10 yards, but Burt shoved sophomore cornerback A.J. Green off of him, tip-toed the sidelines and then turned on the boosters for a 90-yard gain down to two.
"Their punter is - did he win the Ray Guy Award previous year?"
Texas: The Longhorns are at Baylor on Saturday. Amendola made up for it with a 34-yard field goal in overtime.
