William Byron took the lead on the second-to-last lap of overtime to win the NASCAR Cup Series race at Las Vegas and put an exclamation mark on a dominant day for Hendrick Motorsports. The top three drivers were from Hendrick, with Byron beating teammates Kyle Larson and Alex Bowman. Bowman won last year’s March race at Las Vegas. This is Byron’s fifth career victory in his six seasons. He led 176 laps and won both stages.
