NASCAR Cup Series Martinsville race live updates, highlights, leaderboard for YellaWood 500

The math is somewhat complicated, with Christopher Bell (-74) and Chase Briscoe (-79) at a similar range. Joey Logano (-100), Ryan Blaney (-107) and Tyler Reddick (-126) are also still mathematically alive. But if Larson finishes Martinsville with a lead of 77 points or more, he will clinch his third Cup Series championship. If the lead is less than 77 points, the title won't be decided until next week's season finale at Homestead. Another number to note: 59.
