Andretti Autosport has signed 15-year-old Sage Karam to drive for the team in this year's Cooper Tires presents the USF2000 National Championship powered by Mazda, the entry level series for the Indy Racing League's Road to Indy.

The entry marks Andretti Autosport's debut in the Indy Racing League's new "Road to Indy" driver development program. Comfort Revolution, a developer and distributor of specialty bedding mattresses and accessories, and The Michael Fux Foundation will sponsor the effort.

"We look forward to bringing Sage on board as Andretti Autosport's first USF2000 National Championship driver and hope to make him the first driver to go all the way through the 'Road to Indy' program all the way to the IZOD IndyCar Series," said company CEO Michael Andretti. "I've watched him grow to become an accomplished young driver, and I think his experience in karting and Skip Barber will serve him well this year in the USF2000 series. I'm very confident Sage will be successful with Andretti Autosport."

Karam, a native of Nazareth, Pa., has spent the last few years competing in the Skip Barber National championship, a part of the MAZDASPEED Motorsports Development ladder program, as well as the World Karting Association (WKA). He was the only American driver to compete in both a national karting championship and an open-wheel professional series full time in 2009.

"The opportunity to drive for my mentor, Michael Andretti, has always been a dream of mine," Karam said. "I've worked very hard to get to this point, but I know I have a long way to go. Driving in the USF2000 with Andretti Autosport is the best way to reach my ultimate goal: racing in the IZOD IndyCar Series and winning the Indy 500."

Karam began competing in karts at the age of five. He has since established himself as a 35-time WKA and Indy Racing League (IRL) Stars of Karting national champion. Karam also stands as the only driver ever to win a WKA Triple Crown Championship and titles in the IRL Stars of Karting (East, West and National) all in the same year (2007). In 2008, Karam – then 13 – established himself as the youngest winner in the history of the Skip Barber Shootout.
