AVONDALE, Ariz. (AP) Todd Gilliland won the NASCAR K&N Pro Series race Thursday night at age 15 to become the youngest winner in Phoenix International Raceway's 52-year history.
Gilliland is the son of NASCAR Sprint Cup driver David Gilliland. He won an ARCA Series race in Toledo, Ohio, in May, two days after his 15th birthday.
Gilliland took the lead after J.J. Haley's dominating run ended with a blown tire with six laps to go. Haley led every lap until the wreck.
Chris Eggleston finished 10th to win the K&N Pro Series West season championship.
Seventeen-year-old William Byron was second in the race.
