On the 37th lap after a restart, rookie Graham Rahal was hit from behind by Will Power while running 3rd. He was able to continue. Several cautions slowed the race, including a crash by Ryan Briscoe, and a multi-car incident involving Vítor Meira, Franck Perera, and Townsend Bell. On the restart that followed, Rahal-Letterman Racing driver Ryan Hunter-Reay led Graham Rahal. Rahal got the jump and took the lead into the first turn. With time running out before the two-hout time limit, the race was poised to end before the scheduled distance. On the final restart, just under 4 minutes of racing remained. Rahal held off a charging Hélio Castroneves and won his first race.
