Andretti Autosport signs 15-year-old driver

INDIANAPOLIS (AP) -Sage Karam isn't old enough to drive on the streets of his home state. But the Pennsylvania native will be racing on the streets of St. Petersburg, Fla., later this month.

The 15-year-old from Nazareth, Pa., was hired Thursday by Michael Andretti to drive in the USF2000 national championship, which begins March 27-28 in the Florida city. It's the first time Andretti's team will compete in the “Road to Indy” driver development program.

Karam has competed in the Skip Barber national championship and the World Karting Association the past several years. He was the only American driver to compete full-time in a national karting championship and an open-wheel series in 2009.
