William Bryon continued his dominance in the NASCAR Truck Series at Pocono Raceway on Saturday, winning for the fifth time this season.

Byron added the Pocono victory to wins at Kansas, Texas, Iowa and Kentucky.

The 18-year-old Byron survived a race that saw nearly half of its 60 laps run under caution. He set a record for Truck Series wins in a season by a rookie. Kurt Busch had four wins in 2000.

Cameron Hayley was second, followed by Brett Moffitt, Timothy Peters and Cole Custer.

Byron led a race-high 44 laps and added one more win in the No. 9 Toyota for Kyle Busch Motorsports.
