Baker Mayfield threw an 18-yard touchdown pass to Sterling Shepard in double overtime and No. 19 Oklahoma rallied from a 17-point deficit in a 31-24 victory Saturday over No. 23 Tennessee.
Zack Sanchez clinched Oklahoma's victory by picking off a Joshua Dobbs pass in Tennessee's second overtime possession, continuing the Vols' recent history of frustration against Top 25 foes.
Oklahoma (2-0) had forced overtime on Mayfield's 5-yard touchdown pass to Shepard with 40 seconds left.
Tennessee went ahead 17-0 in the first 18 minutes of the game and still led 17-3 until Mayfield engineered two fourth-quarter touchdown drives.
After going 8 of 25 for 84 yards with two interceptions in the first three quarters, Mayfield was 9 of 14 for 103 yards with three touchdown passes plus a touchdown run in the fourth quarter and overtime.
Tennessee (1-1) has lost 28 of its last 29 games against Top 25 teams.
