NORMAN, Okla. (AP) - Rhett Bomar threw a 21-yard touchdown pass to Juaquin Iglesias in the second overtime to lift Oklahoma to a 37-30 win Saturday night against Baylor and maintain the Sooners' perfect record in the series.

The Bears' hopes for their first win against Oklahoma ended when Shawn Bell 's fourth-down pass fell incomplete. The Sooners rushed out onto the field in jubilation, and Baylor players walked to the locker room with their helmets in their hands.

The win moved the Sooners (4-3, 3-1 Big 12) above .500 for the first time this season and continued an undefeated streak against Baylor, which has lost all 15 games against Oklahoma in a series dating back to 1901.

The Bears (4-3, 1-3) rallied from 11 points down to pull within two on a 55-yard touchdown pass from Bell to Dominique Zeigler with 1:17 left. Bell then scrambled for the 2-point conversion to tie it.

A desperation pass by Bomar fell incomplete as time expired in regulation, and the teams exchanged field goals in the first overtime period.

After consecutive runs by Jacob Gutierrez to start the second overtime, Bomar dropped back on third-and-6 and found Iglesias in the right corner of the end zone.

The completion gave him a career-high 269 passing yards and the Sooners the win.

With Adrian Peterson out with a sprained ankle and backup Kejuan Jones suspended, Gutierrez was forced to make his first start at tailback and had 173 yards and two touchdowns on 30 carries.

Gutierrez, a 5-foot-6 sophomore who'd started once before at slot receiver, had touchdown runs of 7 and 28 yards as the Sooners scored 24 points in the second quarter. After Baylor took an early 6-0 lead, the Sooners scored on four consecutive possessions and appeared to be in control with a 24-13 halftime lead.

Shaun Rochon , who had a 98-yard kickoff return for a touchdown earlier in the game, pulled the Bears within 24-19 late in the third quarter when he caught a 7-yard touchdown pass from Bell. Rochon caught the ball at the 5, spun out of Chijioke Onyenegecha 's tackle and walked into the end zone.

Bell finished with 228 yards and three touchdowns on 20-for-44 passing, and Zeigler had 141 yards on nine catches.

Garrett Hartley stretched Oklahoma's lead to 27-19 with a 25-yard field goal with 9:17 to play, and Baylor went three-and-out on its next possession. Colin Allred gave the Bears a chance when he forced a Gutierrez fumble with 2:39 to play and Julian Hill recovered at the Bears 18.

On a third-and-10, Bell found Zeigler deep down the middle, where he had beaten safety Lewis Baker and lofted the ball into his arms.

Baylor struck first with a 20-yard field goal in overtime, but Oklahoma tied the game again on Hartley's 39-yarder.
