NORMAN, Okla. -- After the first overtime game in the Bedlam rivalry, a wild celebration on Owen Field and yet another 500-yard passing game, it all settled in for Landry Jones.

His last home game with Oklahoma was over, and what a way to go out.

Jones threw three touchdown passes and Brennan Clay scored on an 18-yard run in overtime to lift the Sooners (No. 13 BCS, No. 14 AP) to a 51-48 win against Oklahoma State (No. 21, No. 22) in the Bedlam rivalry on Saturday.

"No better way," Jones said. "God blessed me so much tonight to be able to go out like this.

"There's no better way to go out."

The Sooners (9-2, 7-1 Big 12) never led during regulation, wiping out double-digit deficits in both halves. Backup quarterback Blake Bell tied it with 4 seconds left on a 4-yard keeper on fourth-and-1 after Jones directed the first 16 plays of an extended drive.

The victory kept alive Oklahoma's chances for at least a share of the Big 12 championship. The Sooners could win it outright by beating TCU next week if Kansas State loses to Texas.

"Football's a crazy game," Jones said. "There's up sand downs, good and bad. You have to stay somewhere in that middle ground, realizing who you are and what you're capable of and what type of offense you are.

"When you need a play, just go out and make it."

On the Sooners' second play, Clay got through traffic at the line of scrimmage and then broke through attempted tackles by Daytawion Lowe and Shamiel Gary to score the game-winner and set off an unusually giddy celebration on Owen Field.
