O’Ward had a 1.5sec margin over Harvey. Newgarden gas saved by means of the primary 22 laps, however was instructed by strategist Tim Cindric to catch as much as the Meyer Shank automotive earlier than the primary spherical of pitstops. For Newgarden, who had began on the primaries, this got here on the finish of Lap 27, and he took on new alternates, whereas Dixon stopped on Lap 28 to alter from scrubbed blacks to recent blacks. Power received off the reds and onto new primaries on the finish of Lap 30, and the 2 Arrow McLarens stopped a lap later.
Newgarden had been flying on his reds and had a side-by-side battle with Power earlier than nosing forward and pulling away.

The Lap 53 restart noticed Rosenqvist – second on monitor resulting from shedding a lap from a Ferrucci-caused puncture – making an attempt to get previous Rossi however he couldn’t fairly make it.
Behind them, O’Ward moved up as did Dixon, who needed to survive some furry moments as he confronted assault from Harvey, who would quickly be penalized two spots for hip-checking Askew… who did the identical factor on Hunter-Reay out of the hairpin onto the entrance straight.
Marco Andretti, in the meantime, was making nice progress on his reds and handed Harvey and Askew in a single slick maneuver at Turn 4, and dived down the within of Rahal subsequent time by to take seventh.
Well forward of this enjoyable was chief Rossi who by Lap 60 had a 1.9sec margin on Herta, with Hinchcliffe 2.7sec additional again, coming underneath rising strain from Newgarden.

On Lap 63, Herta made an error underneath braking at Turn 4, which allowed Hinchcliffe and Newgarden into second and third. The defending champion didn’t keep there lengthy, as he made one other cease on Lap 65 for major blacks. That compelled the hand of the competitors, Rossi and Dixon pitting on Lap 66, O’Ward on 67. Andretti, Harvey and Bourdais pitted subsequent time by, Hinchcliffe a lap after that, Herta a lap after that – and Colton thereby jumped James to get again to a (web) second.
That allowed Rahal, Hunter-Reay, Askew and Marcus Ericsson into the highest 4 however nonetheless needing their remaining cease. Then the axe fell on their probabilities, as Rossi – who had simply allowed Rosenqvist to get his lap again – misplaced it exiting Turn 3 and smacked into the partitions on both aspect.
So the brand new order was Herta, Hinchcliffe, Alex Palou (off technique and on reds), Newgarden, O’Ward, Dixon, Andretti, Harvey, Sato, and Pagenaud.
However, an enormous transfer by Sato down the within of Harvey at Turn 4, noticed him clip the right-hand-rear of Andretti, deflating his tire and spinning him out at Turn 5.
As the yellow flew, Hinchcliffe spun on the hairpin, restarted and pulled out proper into the trail of Harvey which value him his entrance wing and he couldn’t recover from to drag into the pitlane entrance, so needed to limp round underneath yellow for one more lap.
