Chip Ganassi Racing driver Charlie Kimball surprised with a qualifying run good enough to place him second.

[1] Graham Rahal and Josef Newgarden, who had qualified third and fifth respectively, had their times disallowed and were moved to the back of the starting grid for failing to meet minimum car weight regulations in post-qualifying inspection.

On lap six, Will Power lost control of his car entering turn seven while trying to defend from Alexander Rossi.

Graham Rahal would lead briefly due to extending fuel farther than anyone else, but would fall back following his own pit stop.
