Goodyear 400

Denny Hamlin stole the Goodyear 400 at Darlington Raceway on Throwback Weekend, capitalizing on a late-race caution and a lightning-fast pit stop to win his second consecutive race and 56th of his career, breaking his tie with Rusty Wallace on the all-time wins list. William Byron had dominated all afternoon, leading a staggering 243 of 297 laps, but a caution with three laps remaining for an incident between Kyle Larson and Bubba Wallace erased Byron's advantage and sent the field to pit road. Hamlin's Joe Gibbs Racing pit crew delivered the fastest stop of the day, and the veteran driver converted that track position into a 0.597-second victory over Byron on the overtime restart.

The dramatic finish robbed Byron of what appeared to be a certain victory on the Lady in Black's abrasive surface. Ryan Blaney had briefly seized the lead from Tyler Reddick with three laps to go before the caution froze the field, and the subsequent restart shuffle left both Blaney and Reddick watching Hamlin pull away. Christopher Bell completed a JGR 1-3 finish by running third, while the Throwback Weekend paint schemes honoring legends like Dale Earnhardt and Jeff Gordon added an emotional layer to the proceedings. The race featured eight cautions for 45 laps across the extended 297-lap distance.

For Hamlin, the consecutive victories at Martinsville and Darlington validated the early returns of his partnership with Chris Gayle and silenced any remaining doubts about the No. 11 team's trajectory. Byron's 243 laps led were the most by any driver in a single race to that point in the season, making his runner-up finish a particularly cruel result for a driver who did everything right except pit under that final caution.
