ARLINGTON, Texas (AP) — Rhamondre Stevenson had a 5-yard touchdown run in overtime and No. 6 Oklahoma made its bid for another playoff berth with a 30-23 win over No. 7 Baylor in the Dr Pepper Big 12 Championship game Saturday.

“We didn’t play our best, but we beat a damn good team here today, and we’re the champs,” coach Lincoln Riley said.

A day after No. 5 Utah lost in the Pac-12 championship game, and before No. 4 Georgia took on No. 1 LSU for the SEC title, the Sooners (12-1, No. 6 CFP) won their fifth consecutive Big 12 title, and 13th overall. Oklahoma went to the playoff three of the past four seasons.

“I like our case,” Big 12 commissioner Bob Bowlsby said before the game about his league’s playoff chances.

Baylor (11-2, No. 7 CFP) tied the game in the fourth quarter after two long passes by freshman Jacob Zeno, the second quarterback used after starter Charlie Brewer left the game in the second quarter following a big hit he delivered on a defender.

There was an 81-yard catch-and-run touchdown by Trestan Ebner with 9:41 left in regulation and a 78-yarder to Chris Platt that set up John Mayers’ third field goal, a 27-yarder with 3:25 left to make it 23-all.

After Oklahoma scored on three plays to start overtime, Zeno was under tremendous pressure on Baylor’s chance. There were two incompletions before he was sacked for a 10-yard loss, and then he was under distress again when he flung a game-ending pass that fell to the ground.

The Bears had only 105 total yards before the 81-yard TD pass in the fourth quarter. They finished with 265.

“They played like they have the majority of this year. There’s some great defense being played at the University of Oklahoma right now,” Riley said. “Man, I’m proud of those guys.”

Jalen Hurts, who last year led Alabama’s comeback win over Georgia in the SEC title game, was 17-of-24 passing for 278 yards and a touchdown. CeeDee Lamb, the Championship's Most Outstanding Player, had eight catches for 173 yards after missing the previous game against the Bears.

It was the second time in four games that Oklahoma beat the Bears, who in coach Matt Rhule’s debut season two years ago lost 11 games with a depleted roster.

Brewer was taken out of the game not long after bulling over a defender at the end of a 7-yard run early in the second quarter. He finished that series and played one more before Gerry Bohanon took over after referee Mike Defee told Rhule that the starter needed to be checked.

Bohanon directed Baylor on scoring drives on its last two possessions before halftime. He threw a 33-yard touchdown to Tyquan Thornton before a 28-yard field goal by Mayers put the Bears up 13-10 at halftime — even with only 98 total yards — after they trailed 10-0.

Three weeks after their biggest comeback ever, a 34-31 win at Baylor after a 25-point deficit, the Sooners jumped ahead 10-0 in the first quarter.

Lamb turned a short catch into a 71-yard gain to the 7 on Oklahoma’s second drive, setting up Kennedy Brooks’ 6-yard TD run. On the next drive, Lamb’s 26-yard catch to the Baylor 19 came before Gabe Brkic kicked the first of his three field goals.
