Corey Day made a thrilling late-race pass with four laps remaining to win the BetRivers 200 at Dover Motor Speedway, securing his second career NASCAR O’Reilly Auto Parts Series victory.
A key incident involved Rajah Caruth and Jesse Love colliding while battling for the lead, which affected the race dynamics and allowed Justin Allgaier to briefly regain control.
Justin Allgaier led a race-high 71 laps and finished second, extending his NASCAR O’Reilly Auto Parts Series championship lead over Sheldon Creed to 175 points.
“Man, I was hoping that’s how it would play out,” Day said. “I saved so hard there early in the last run once we put on tires and the yellow came out and I thought it was all for nothing, but it all just worked out good.”
“This one feels really special.”
The late pass capped a dramatic final run that saw multiple contenders battle for control of the race throughout the afternoon.
The incident opened the door for Allgaier to briefly reclaim control before Day hunted down the JR Motorsports veteran in the closing laps.
Rajah Caruth said, “I’m not sure how to handle it,” Caruth said. “I’ve been the one to ruin their day multiple times. All I can do is my best.”
Allgaier finished second after leading a race-high 71 laps. The result marked his 18th top-10 finish in 26 career races at Dover Motor Speedway and his 12th top-10 result of the 2026 campaign.
Sam Mayer delivered another strong run at Dover, finishing third for his fourth top-10 finish in five career starts at The Monster Mile.
William Sawalich crossed the line fourth, while Austin Hill rounded out the top five with his best finish since March.
Ross Chastain appeared to be one of the fastest cars in the field after leading 68 laps and winning Stage 2, but his bid for the victory ended shortly after the halfway point following contact with Taylor Gray that sent both drivers spinning.
Brendan Jones captured the Stage 1 victory, while JR Motorsports driver Carson Kvapil extended the organization’s top-10 streak to 71 consecutive races with a sixth-place finish.
Ryan Sieg, Sammy Smith and Anthony Alfredo rounded out the top-10 finishers.
The action continues Sunday at Dover Motor Speedway with the NASCAR All-Star Race taking the green flag at 1 p.m. ET. NASCAR’s biggest stars will battle at The Monster Mile in one of the sport’s premier events. Denny Hamlin will start from the pole position, while the No. 38 team secured the first pit selection after winning the Mechanix Wear Pit Crew Challenge earlier Saturday afternoon.
