Overview
- Christopher Bell passed Kyle Larson with about a dozen laps remaining to win the Cook Out Southern 500 at Darlington on Sunday night, ending a nearly yearlong win drought and scoring his first Cup victory of 2026.
- Rain late in the race produced a red flag and a restart where Larson led on older tires before Bell, on fresher rubber, made the decisive inside pass and held off teammate Ty Gibbs for the win.
- Weather canceled practice and qualifying for the weekend so NASCAR set the starting grid by its performance metric, giving Tyler Reddick the pole and altering early race strategy.
- Denny Hamlin suffered toe-link damage after contact with Michael McDowell, lost track position and finished 18th but kept the Chase points lead, which narrowed to a 12-point margin over Bell.
- Toyota swept the podium with Bell, Ty Gibbs and Reddick and William Byron’s late engine failure dropped him to 37th and caused a steep fall in his Chase standings as the series heads to Gateway on Sept. 13.
