Ryan Hunter-Reay (Andretti Autosport) earned his second victory in as many weeks after finishing on top of an eventful race at the Iowa Speedway on Saturday night.
It looked as though the conclusion of the race would be settled by a race between some of the night's leaders but, with only four laps to go, Dragon Racing's Katherine Legge spun and brought out a caution, leaving the race to finish under yellows.
Tony Kanaan (KV Racing Technology) hanged on with the leading pack and moved over Scott Dixon (Ganassi) late in the race to take third behind Hunter-Reay's teammate Marco Andretti.
Dixon held on for fourth ahead of Schmidt Hamilton's Simon Pagenaud, who had to battle his way all the way to the front after being penalized and sent to the back of the grid for a engine change.
Things got difficult for pole-sitter Dario Franchitti (Ganassi) as he had to retire after his engine blew up during a warm-up lap.
Franchitti wasn't the only one struck by bad luck as more than eleven cars failed to finish, including championship leader Will Power, who was involved in an accident with EJ Viso (KV).
Penske's Ryan Briscoe had his own run-in with Sarah Fisher Hartman's Josef Newgarden that resulted in both drivers' retirement.
Oval championship leader and runner-up in the standings James Hinchcliffe on the other hand put his Andretti Dallara-Chevrolet into the barriers all by himself.
