ARLINGTON, Texas — Baker Mayfield threw four touchdowns and No. 2 Oklahoma staked claim to a playoff spot with a 41-17 victory against No. 10 TCU in the return of the Big 12 championship game Saturday.

With their record 11th Big 12 title, the Sooners (12-1) are a lock to be in the College Football Playoff for the second time in three seasons. They are the only Big 12 team to make the four-team playoff format that started in 2014.

Oklahoma jumped out to a 17-0 lead, including Caleb Kelly’s 18-yard fumble return for a touchdown after running back Kyle Hicks’ turnover on the first offensive play by TCU (10-3).

Kenny Hill threw two TD passes to get the Horned Frogs within 24-17 at halftime, but Oklahoma scored twice on its first three offensive plays after the break.

Auburn was the hottest team in the country, rolling into Atlanta after wins over Georgia and then-No. 1 Alabama in its last three games. But the Tigers were stymied by two crucial turnovers, a blocked field goal and a Georgia team eager to make up for its embarrassing 40-17 defeat to Auburn.
