Dale Earnhardt Jr. shared his reaction to Denny Hamlin’s dramatic win at Dover Motor Speedway on social media. The post came shortly after Hamlin clinched a major feat, his fourth win of the 2025 NASCAR season. He is the first driver to have attained 4 race wins this season.Hamlin’s win at Dover wasn’t handed to him easily. After a one-hour rain delay with just 13 laps remaining, NASCAR dried the soaked concrete and set up a final sprint. In the closing laps, Hamlin had to hold off teammates Christopher Bell and Chase Briscoe, both of whom were charging hard with fresher tires.On the first restart after the rain delay, Bell spun while racing Hamlin for the lead, causing a crash that also involved William Byron and Noah Gragson. Briscoe then moved up to second and challenged Hamlin in double overtime. They made contact near the white flag, but Hamlin held on and pulled ahead to win. Addressing this race performance, Dale Earnhardt Jr. wrote on his X account,“Dover was interesting for sure. Great run to the finish. Glad Nascar gave it the best effort to see the checkered. Indy next.”It was also Hamlin’s 58th career Cup Series win and his second consecutive win at Dover. With four wins in the current season, Hamlin is a top contender in 2025. Meanwhile, Briscoe finished second, followed by Alex Bowman, Kyle Larson, and Ty Gibbs. The rest of the top ten featured Chase Elliott, Bubba Wallace, Ryan Blaney, Chris Buescher, and Brad Keselowski.“Absolutely miserable inside the racecar”: Dale Earnhardt Jr. warns fans about brutal heat ahead of NASCAR Cup Series race at DoverBefore the green flag waved at Dover Motor Speedway, Dale Earnhardt Jr. took to X to share just how tough Sunday’s conditions would be for drivers.
