The Pennzoil 400 at Las Vegas Motor Speedway appeared to be in the hands of Hendrick Motorsports driver Kyle Larson, but a late-race caution sent the race into overtime and bunched the field up for a final restart.
Larson's teammate William Byron was able to retake the lead after a dominant day to earn the victory and deliver a 1-2-3 finish for Hendrick Motorsports.
