As the Kaulig trio approached the checkered flag, Haley’s No. 11 Chevrolet edged ahead to hold off Allmendinger and claim his first win of the season.
“It’s been a tough year – we’ve had a lot of bad luck,” Haley said. “I was trying to formulate the plan. Hats off to Kaulig Racing, I think we got the teammate thing down. It’s just so special to win here at Daytona.
“I’ve won twice at Daytona and neither time did I get to see anyone on the frontstretch, so thank you guys for being here. I love you.
“This was absolutely incredible. It was a close one to just beat out A.J., who always leads a lot of laps here.”
The win is Haley’s fourth career win in the series and second at Daytona. It’s also the fifth win by a Kaulig driver in the 2021 season.
