Blake Bell passed for 413 yards and four touchdowns in his first start as quarterback for No. 14 Oklahoma and the Sooners beat Tulsa 51-20 on Saturday.
Sterling Shepard caught eight passes for 123 yards and two touchdowns - all career highs - and Jaz Reynolds had 109 yards receiving and one score for Oklahoma (3-0). The Sooners scored on their first five possessions against Tulsa (1-2) to continue their dominance in the series, having won 12 of the last 13 games between the in-state rivals.
The Sooners are 13-0 against Tulsa as a ranked team and 7-0 against the Golden Hurricane since Bob Stoops became Oklahoma's coach in 1999.
Oklahoma is 3-0 for the third time for four seasons, heading into a showdown in two weeks at No. 21 Notre Dame, which beat the Sooners last year in Norman.
