Hunter-Reay overtook Darren Manning in the No. 14 ABC Supply Co. car for A.J. Foyt Racing in Turn 1 on a Lap 51 restart and hung on the remaining nine laps. Tony Kanaan finished third and Buddy Rice was fourth. Marco Andretti finished fifth. Dale Coyne Racing’s Bruno Junqueira was sixth and Mario Moraes seventh — IndyCar Series bests for both drivers.

“It’s a dream come true,” Hunter-Reay said. “American kid winning with ethanol on the side of the car. It’s an American team – Bobby Rahal gave me the job and now we’re in Victory Circle. I can’t tell you how happy I am. This is amazing.”

It was the first victory for Rahal Letterman Racing since Michigan in 2004 with Rice.

“I just got a good run on Darren, stuffed it down in there, and said I’ll deal with it when it happens,” Hunter-Reay said. “Then I got to the top of the hill, Darren popped to the outside so I stuck to the inside and we held on to it from there.”

IndyCar Series points leader Scott Dixon, who was seeking a series-record fourth consecutive victories at The Glen, finished 11th. His No. 9 Target Chip Ganassi Racing car spun in Turn 10 as he was warming up the tires under yellow on Lap 49 and was struck in the rear by the No. 6 Team Penske car of pole sitter Ryan Briscoe. Briscoe, who led a field-high 37 laps, finished 12th.
