Byron claims first Xfinity victory
NEWTON, Iowa — Rookie William Byron grabbed the lead with just over 20 laps and won the NASCAR Xfinity race at Iowa Speedway on Saturday night for first series victory.
A seven-time winner last year in the Truck Series, Byron, broke through just a week after an agonizingly close loss to Denny Hamlin at Michigan.
Ryan Sieg was second in the stand-alone race with no Monster Energy Cup regulars in the field.
