The NASCAR O’Reilly Series competed at Dover Motor Speedway, and as usual, it was an amazing event. Brandon Jones won Stage 1 while Ross Chastain won Stage 2; however, neither driver entered victory lane. Instead, it was a Hendrick Motorsports driver who made a late-race pass to tame the Monster Mile.
Corey Day and the No. 17 team for Hendrick Motorsports won the BetRivers 250 at Dover, earning their second victory of the 2026 O’Reilly Series season. Day passed JR Motorsports driver Justin Allgaier, with under five laps to go, when a lap car affected the No. 7 vehicle. The driver of the No. 17 car took advantage while running the top lane.
Day has been an emerging star in the O’Reilly Series, and Saturday’s race at Dover was the perfect example. The Hendrick Motorsports driver is turning into a championship threat with his speed and consistency. Day has significantly developed in 2026, and there are more victories on the way.
