Who won the NASCAR Xfinity Series race today?

Driving the #17 Chevrolet for Hendrick Motorsports, William Byron won Saturday’s Xfinity Series race at Charlotte Motor Speedway in overtime after recovering from a pit-road speeding penalty.

Byron emerged victorious when he grabbed the lead from Justin Allgaier through Turn 4 of the first lap of overtime and stayed out front until a wreck involving Jeb Burton and Brennan Poole brought out the caution and froze the field.

NASCAR Cup Series star led 71 laps and crossed the finish line 0.302 seconds ahead of Xfinity Series rookie Connor Zilisch to take the checkered flag. It marked Byron’s fifth career win in the Xfinity series.
