Thursday morning, Hendrick Motorsports announced it signed NASCAR Camping World Truck Series points leader William Byron to a long-term driving deal.

Next year, Byron will race a full NASCAR XFINITY Series schedule for Hendrick affiliate JR Motorsports and at some point afterwards will presumably move up to Hendrick's NASCAR Sprint Cup Series team.

Heavy stuff for a young man who is just 18 years old but already has won five races this season.
