NORMAN, Okla. (AP) Baker Mayfield passed for 388 yards and three touchdowns, and Joe Mixon had 142 yards from scrimmage to help No. 19 Oklahoma defeat Akron 41-3 on Saturday night.

Mayfield set a school record for yards passing in a season opener, surpassing the previous mark of 363 yards by Sam Bradford in 2007. The walk-on transfer from Texas Tech won the starting job in a preseason battle with last year's starter, Trevor Knight.

Mixon, a redshirt freshman who was suspended last season after punching a woman in the face at a restaurant, caught a 76-yard touchdown pass from Mayfield early in the third quarter.
