Rookie William Byron took the lead on lap 82 and withstood several challengers to win Thursday night at Kentucky Speedway and make Kyle Busch Motorsports the winningest Camping World Truck Series team in NASCAR history.

Daniel Hemric and John H. Nemechek battled side-by-side at time down the stretch in hopes of catching Byron but neither could chase down the series points leader, who passed Timothy Peters and didn't look back en route to KBM's 51st career victory.

The 18-year-old Byron led two times for 70 laps in the 225-mile race in the No. 9 Toyota for his fourth win this season and second in three starts. Nemechek finished second in a Chevy, followed by Hemric (Ford), rookie Christopher Bell (Toyota) and Johnny Sauter (Chevy).

Byron's win offered some consolation for the team owner and Sprint Cup Series champion, who finished 30th after hitting the wall following contact with Spencer Gallagher on lap 58.
