William Byron Wins Charlotte Xfinity Race After Penalty

William Byron won his fifth career NASCAR Xfinity Series race and his first since 2017 at Charlotte Motor Speedway, just one day after signing a contract extension with Hendrick Motorsports through 2029. Byron overcame a pit road speeding penalty at the end of Stage 2 and fought back from the rear of the field, aided by several late-race cautions. He swept both stages and led 71 laps in what was his final scheduled start in the No. 17 Chevrolet this season. Justin Allgaier, who led 101 of 205 laps, opted to stay out on older tires during a late caution but was overtaken in overtime by Byron, Connor Zilisch, and Nick Sanchez, finishing fourth. Connor Zilisch finished second in his return from injury, and Nick Sanchez placed a career-best third. The Xfinity Series will return next week at Nashville Superspeedway.
