CONCORD, N.C. (AP) -- Nextel Cup rookie Kyle Busch became the youngest winner in Craftsman Truck Series history, holding off Terry Cook and Ted Musgrave in a three-lap closing sprint Friday night at Lowe's Motor Speedway.

The 20-year-old Busch beat the previous mark set by the late Ricky Hendrick, 21 when he won in 2001. That also was the year Busch burst on the truck scene as a 16-year-old high school student, nearly winning a couple of races as a rookie.

But NASCAR changed the rules following that season, setting a mandatory age of 18 for its major series and sending Busch back to the lower leagues. He eventually made it back with Hendrick Motorsports -- the team founded by Hendrick's father -- and last season he tied Greg Biffle's Busch Series record of five victories for a rookie. More
