Only Kyle Larson is safe in Championship 4. In addition to winning Martinsville, here’s how the other three will be determined:
Waypoints: If there is a repeat winner, or a victory for a driver outside the top eight, subsequent drivers could clinch ahead of the fourth driver without a win in the standings. The scenarios below would be true if another win came from Chase Elliott, Denny Hamlin, or Kyle Busch.
Chase Elliott: Would win with 20 points, 22 points if Kyle Busch wins
Denny Hamlin: Would win with 23 points, 24 points if Kyle Busch wins
Kyle Busch: would win with 54 points
Ryan Blaney: Would clinch with 55 points, need help if Kyle Busch wins
Martin Truex Jr.: Would clinch with 55 points, need help if Kyle Busch wins
Brad Keselowski and Joey Logano: Could only get off with help
If there is a new winner from Ryan Blaney or another winless driver lower in the standings but still eligible for the Championship, subsequent drivers could clinch ahead of the third winless driver in the standings.
Chase Elliott: would win with 22 points
Denny Hamlin: would win with 25 points
Kyle Busch, Ryan Blaney, Martin Truex Jr., Brad Keselowski: Could only get off with help
