No. 5 Baylor 41, No. 8 Oklahoma 12: Bryce Petty threw for three touchdowns and ran for two more scores as the Bears overcame a slow start and improved to 8-0 for the first time in school history with a dominant effort against the visiting Sooners.

Petty completed 13-of-26 passes for 204 yards and rushed for 45 yards on 16 carries to lead Baylor (8-0, 5-0 Big 12), which trailed 5-3 early in the second quarter before reeling off 28 consecutive points. Shock Linwood rushed for a career-high 182 yards in place of Glasco Martin IV and Lache Seastrunk, who each suffered injuries in the first half.

Blake Bell was 15-of-35 for 150 yards with a touchdown and two interceptions for Oklahoma (7-2, 4-2), which lost for the second time in 24 games against the Bears. The Sooners were 4-for-17 on third-down conversions and rushed for 87 yards, well below their season average of 234.
