Monster Energy NASCAR Cup Series rookie William Byron led the final practice round before Daytona 500 qualifying Saturday, circling Daytona International Speedway at 201.681 mph in the No. 24 Hendrick Motorsports Chevrolet.
Byron earned the top spot despite a couple of close calls with other drivers when the No. 24 drifted up the track in the draft.
“Yeah, that was one of those ‘Oh, shoot!’ moments, but that was a lot of fun,” Byron said. “That was the best chance for me to really learn what I needed to do in the draft.”
Ricky Stenhouse Jr. was second-fastest in practice, logging a speed of 201.649 mph in the No. 17 Roush Fenway Racing Ford.
Joey Logano was third in the No. 22 Team Penske Ford at 201.608 mph, while Denny Hamlin finished fourth in the No. 11 Joe Gibbs Racing Toyota at 201.464 mph.
David Ragan rounded out the top five in the No. 38 Front Row Motorsports Ford.
NASCAR told teams to make a gear change for Saturday’s final practice, though speeds still increased from the initial practice, where Kyle Busch had the fastest car at 199.743 mph.
The practice was the final one before Daytona 500 qualifying Sunday at 12:15 p.m. ET (FOX).
