Bryce Petty threw for two touchdowns and ran for another score, helping No. 10 Baylor open its riverfront campus stadium with a 45-0 victory over former Southwest Conference rival SMU on Sunday night.
Petty played two quarters because of a bruise to his lower back after taking an early shot. He threw for 161 yards while moving gingerly at times and often grabbing at his back.
Big 12 champion Baylor (1-0) led 24-0 after one quarter. It had a 6-yard TD drive after an SMU fumble and a 4-yard drive after Levi Norwood's 45-yard punt return.
The Bears sacked SMU's three quarterbacks a combined eight times and held the Mustangs (0-1) to 67 total yards.
On the day a statue of Robert Griffin III was dedicated, Petty extended his streak with at least one touchdown pass to a school-record 14 games, breaking a tie with Baylor's only Heisman Trophy winner.
