The NASCAR Xfinity Series returns to the high-banks of Talladega Superspeedway for Saturday afternoon’s Ag-Pro 300 (4 p.m. ET on The CW Network, MRN and SiriusXM NASCAR Radio). The bemouth 2.66-mile track always provides a season highlight reel and has all the trappings for another headline-making show this weekend.
