After weeks of debate, patience paid off for Oklahoma.

The Sooners beat Baylor in overtime in Saturday's Big 12 Championship Game, earning OU a spot in the College Football Playoff.

No. 4 OU will face No. 1-ranked LSU in the Peach Bowl at 3 p.m. on Dec. 28 in Atlanta. The official announcement took place Sunday morning.

The other semifinal features No. 2 Ohio State vs. No. 3 and defending national champion Clemson at 7 p.m. on Dec. 28 in the Fiesta Bowl in Glendale, Arizona. The two winners play in the CFP National Championship on Jan. 13 in New Orleans. Both semifinals are broadcast by ESPN.

The Sooners victory in the Big 12 Championship Game, coupled with LSU's blowout win over Georgia in the SEC Championship Game and Ohio State's comeback against Wisconsin in the Big 10 Championship, opened the door to OU's fourth CFP berth in the last five years.

That door looked mostly closed when the Sooners were ranked 10th in the CFP after their narrow win over Iowa State.

The Sooners, 12-1 overall, have yet to win a game in the playoff, coming closest in 2017 when they dropped a double-overtime semifinal decision to Georgia. OU lost to Alabama 45-34 in last year's CFP semifinal in the Orange Bowl.

OU needed to beat Baylor, ranked seventh in the CFP top 25, and have an SEC championship game win by LSU over No. 4 Georgia to earn a playoff spot.

The Tigers knocked off the Bulldogs 37-10. Oregon opened the door for OU or Baylor to make the playoff when it beat No. 5 Utah in the Pac-12 Championship Game on Friday.

Ranked sixth heading into championship weekend, the Sooners scored first in overtime on a Rhamondre Stevenson 5-yard run. Then OU's defense held the Bears to minus 11 yards on four downs to seal the game.

The Bears, 11-2, lost to OU 34-31 in Waco three weeks ago, losing a 21-point lead in the second half. The Bears played the second half Saturday without starting quarterback Charlie Brewer, who was evaluated for a concussion in the first half after a hit from Kenneth Murray. Baylor had just seven completions and less than 80 yards passing through three-plus quarters.

But the Bears got within 23-20 in the fourth quarter when their third quarterback of the day, Jacob Zeno, found Trestan Ebner for an 81-yard touchdown. Zeno found Chris Platt for a 78-yarder later in the fourth quarter, setting up the 27-yard field goal that tied the game at 23 with 3:25 left.
