In case you thought his nearly winning the Indy 500 was a fluke, on Sunday Marco Andretti became the youngest driver in U.S. history to win a major-league open wheel race when he captured the Infineon Indy Grand Prix in Sonoma, California. The 19 year-old son of Michael Andretti, and grandson of former world champion Mario Andretti, also locked up the IndyCar Series Rookie of the Year title in the process.
Marco beat Andretti Green Racing teammate Dario Franchitti to the line by only 0.6 seconds, after gaining the lead on a brilliant out-of-sequence pit stop call by crew chief Kyle Moyer. The two AGR cars were 10 seconds clear of third place Vitor Meira (Panther Racing).
On the championship front, the IndyCar Series heads into its last race at Chicagoland Speedway with Helio Castroneves holding just a one-point lead over Penske Racing teammate Sam Hornish Jr.
