Monster Energy NASCAR Cup Series
Already clinched: Martin Truex Jr., Kyle Larson, Kyle Busch, Kevin Harvick, Brad Keselowski, Denny Hamlin, Jimmie Johnson, Ricky Stenhouse Jr., Ryan Blaney, Kurt Busch, Ryan Newman, Kasey Kahne, Austin Dillon.
Bristol scenarios: No one can clinch on points yet. The only way a driver can clinch a playoff spot is with a win and a top 30 spot locked up. Drivers from Ty Dillon (23rd in points) and higher have already locked up a top 30 spot and would automatically clinch a spot with a win. Paul Menard, Chris Buescher, AJ Allmendinger, Michael McDowell and Danica Patrick need a win and some help to lock up a spot.
Note: Martin Truex Jr. can clinch the regular-season championship if he leaves Bristol with a 121-point lead over second place (or a 120-point lead on second place if the second-place driver has only one win leaving Bristol). He currently has a 129-point lead on second place.
