On lap 7, Scott Dixon pulled off course and rolled to a halt in turn five with engine failure, leaving him with a last place finish.

At the first round of stops, Power easily emerged back in the lead, but Kanaan was challenged by Graham Rahal for second place.

As the race approached lap 40, the last round of pit stops came, with the running order remaining Power, Pagenaud, Kanaan, Rahal.

On lap 40, the race's only caution period came out after the rear suspension on Conor Daly's car failed, sending him off course and into the wall in turn one.

On the restart on lap 44, Power held his lead, while Tony Kanaan moved past Simon Pagenaud into second.

In a repeat of the Indianapolis 500, Pagenaud reported that his engine had developed a misfire, causing him to drop quickly down the running order.
