Byron wins at New Hampshire in 1st NASCAR Trucks Chase race

LOUDON, N.H. (AP) William Byron dominated Saturday at New Hampshire Motor Speedway and won the inaugural Chase race in NASCAR's Trucks Series.

The 18-year-old Byron won for the sixth time this season and advanced to the second round of the Chase.

Christopher Bell was second, followed by Matt Crafton, non-Chase driver Tyler Reddick and Timothy Peters.

NASCAR expanded its Chase format this season to include the feeder Xfinity and Truck Series, its champions now crowned in a four-driver shootout at the season finale. The format mostly mirrors the playoff setup used to determine the Sprint Cup champion the last two years.

Trucks will use a seven-race Chase to decide a champ. In Trucks, the format is eight drivers cut down to six and then a final four at Homestead.
