William Byron became the youngest pole winner in Darlington Raceway history Saturday, putting the No. 24 Hendrick Motorsports Chevrolet on the pole for Sunday's Bojangles' Southern 500.
Bearing a throwback paint scheme honoring driver Cole Trickle from the movie "Days of Thunder," Byron, 21, turned a lap of 172.487 mph to top Brad Keselowski (172.088).

Kyle Larson, Kurt Busch and Daniel Suarez rounded out the top five on the grid.
"The car was really good for us," Byron told NBCSN. "We'll see what happens. It's a really long race. We're in good shape in the points, so we can be aggressive."
It's Byron's fourth career pole, all of them coming this season. By the way, Byron becomes only the third driver to win the pole for the Daytona 500, Coca-Cola 600 and Southern 500 in the same season, joining Fireball Roberts and Bill Elliott.
