19 drivers in contention for 4 Chase slots (The Associated Press)

As the NASCAR Sprint Cup Series heads to Richmond for the final event in the 26-race regular season, there are 19 drivers competing for the final four berths in the Chase for the NASCAR Sprint Cup. Eleven drivers can clinch a Chase spot only with a victory in Saturday night's Federated Auto Parts 400 at Richmond International Raceway (7:30 p.m. ET on NBCSN). Ryan Blaney, AJ Allmendinger, Trevor Bayne, Ricky Stenhouse Jr., Paul Menard, Greg Biffle, Danica Patrick, Aric Almirola, Clint Bowyer, Casey Mears and Landon Cassill are comfortably within the top 30 in the Sprint Cup standings, but their only path to the playoffs consists of winning at Richmond.
