Newgarden lined up on the outside of the front row and fell into line behind Power but on a Lap 23 restart he took advantage of the #12 car getting sideways under throttle to dive under Power at Turn 1 and claim the lead.
Newgarden thereafter held off challenges from Power, championship leader Marcus Ericsson of Chip Ganassi Racing and Pato O’Ward to lead 208 of the 250 laps and claim his fourth victory at the 0.894-mile D-shaped oval in Newton, IA.
