Bryce Petty threw four touchdown passes, leading No. 8 Baylor to a 63-21 victory against Buffalo on Friday night.

Petty went 23 of 34 for 416 yards through three quarters, and Shock Linwood had 98 yards rushing and two touchdowns for Baylor (3-0). Hawthorne Lynx and Jay Lee each caught two touchdowns passes.

The Bears scored on their first four possessions on their way to a 35-0 halftime lead. Baylor had more touchdowns (five) than Buffalo had first downs (four) in the first half.

The Bulls (1-2) scored twice on consecutive possessions in the third quarter. Joe Licata hit Devon Hughes for 41-yard touchdown pass, and Anthone Taylor scored on a 41-yard run.
