Nineteen-year-old Graham Rahal, in his first ever IndyCar race, has won the Grand Prix of St-Petersburg and his victory made him the youngest winner ever in a major open-wheel race - 74 days younger than Marco Andretti was when he won at Infineon Raceway in 2006. "It doesn't get any sweeter than this," Rahal said. "I knew we had the pace and I knew if we stayed calm; if I could attack the car, we could pull away. You don't want your focus to get off the car and the race, and we never did."Helio Castroneves who was able to challenge Rahal the late stage of the race finished second in front of pole-sitter Tony Kanaan, who led early as the race started under wet conditions but fell behind as his team tried a different strategy. The race began with 10 laps under caution while sweepers attempted to reduce large puddles on the track following a downpour minutes before the scheduled start.Six of the first 10 drivers were from the former Champ Car Series.
