Byron dominated much of Saturday night’s race, leading 212 of 403 laps, but a late caution sent the event into a two-lap overtime and bunched the field one last time.
Byron cleared for the lead and took the white flag but Logano tried to get to his rear bumper off Turn 4 for a pass but couldn’t complete it and Byron took the checkered flag by 0.303 seconds for his first win at Martinsville (Va.) Speedway.
