After watching his Hendrick Motorsports teammate Kyle Larson – who dominated most of the race – wreck out late, Byron got around Bubba Wallace and Chase Briscoe on a restart with five of 267 laps remaining to take the lead for the first time.
Byron, 25, then held off a late charge by Ross Chastain and cleared him by 1.863 seconds to take the win – team owner Rick Hendrick’s 300th Cup victory.
