After a wild overtime shootout at Talladega Superspeedway, the NASCAR Cup Series championship picture has been entirely reshaped. Kyle Larson took the victory in the YellaWood 500 by leading 23 laps and surviving a chaotic finish after dropping as far as 11th on the final lap. It was an improbable win given his previous 0-for-58 record in the draft. Larson now holds a 73-point advantage over Denny Hamlin heading into the Xfinity 500 at Martinsville Speedway, putting him in a position to potentially secure the title this weekend, though he will still need to start the race at Homestead-Miami Speedway to officially be crowned champion.
Larson controls his own destiny with his 73-point lead. The defending champion turned up the wick once September arrived, finishing sixth or better in the first six Chase races while banking wins at Gateway and Kansas to snap a 51-race winless streak. Sporting a 2.83 average finish, he posted the second-best six-race stretch in Cup Series postseason history. His only postseason mishap came at Phoenix due to an ill-handling car and a tire failure resulting in a 34th-place finish, before bouncing back at Talladega. Racing Insights projects a 92.3% chance of him winning the championship, with a 36.8% chance of clinching on Sunday if he scores 59 points.
Denny Hamlin trails by 73 points and sits as the closest challenger. The No. 11 driver has suffered issues in nearly every Chase race, posting just two top fives, including a slow pit stop and contact with Michael McDowell at Darlington, a Stage 1 spin at Las Vegas, and a flat tire at Phoenix. Racing Insights gives the Joe Gibbs Racing driver a 4.1% chance of winning the title. Hamlin needs to outscore Larson by 74 points over the final two races and must leave Martinsville within 22 points of Larson to control his own destiny at Homestead. If Larson outscores Hamlin by three or more points on Sunday, Hamlin is eliminated. Should Hamlin win both Martinsville and Homestead, his odds jump to 60%.
Christopher Bell sits 74 points back, with Racing Insights projecting his title odds at 2%. Bell opened the postseason with a crown-jewel victory in the Southern 500 and finished sixth or better in five of the first eight races, but suffered damage at Gateway, power steering woes at Las Vegas, and a solo crash during green-flag pit stops at Talladega that left him 35th. To remain eligible entering Homestead, Larson cannot outscore him by two or more points at Martinsville. Winning the final two races would increase his title odds to 49.4%.
Chase Briscoe trails by 79 points, backed by a 1.3% championship projection from Racing Insights. The No. 19 Joe Gibbs Racing driver started the postseason with a sixth-place finish at Darlington, but saw trouble when he was caught in Chase Elliott's brake rotor failure at Gateway and suffered late wall contact at Bristol. He bounced back by ripping off back-to-back wins at Las Vegas and Charlotte Motor Speedway before a DNF at Talladega. To stay in the fight entering Homestead, Briscoe needs to outscore Larson by three or more points at Martinsville, while victories in the final two races would raise his odds to 49.8%.
Joey Logano, Ryan Blaney, and Tyler Reddick remain mathematically eligible despite facing Herculean deficits, with Racing Insights projecting all three at 0.1% odds. Logano trails by 100 points and needs to outscore Larson by 25 or more at Martinsville; Blaney trails by 107 and needs to outscore Larson by 32 or more; Reddick trails by 126 and needs to outscore Larson by 51 or more. Winning the final two races would boost Logano's odds to 23%, Blaney's to 9.1%, and Reddick's to 2.7%. Meanwhile, Austin Cindric, Ty Gibbs, Carson Hocevar, William Byron, Chase Elliott, Bubba Wallace, Daniel Suárez, Ryan Preece, and Chris Buescher have all been mathematically eliminated from championship contention.
