Following the final round of stops in which his Chip Ganassi Racing-Honda teammate Scott Dixon, who had led 95 laps, was pinged for speeding on pitlane, Marcus Ericsson emerged third behind the two Arrow McLaren SP-Chevrolets of Felix Rosenqvist and Pato O’Ward. But he passed the pair of them to take the lead, which he built up to three seconds – the biggest advantage anyone had held all day.
Then on the 194th lap, his teammate Jimmie Johnson, making his Indy 500 debut, struck the wall at Turn 2, bringing out first the yellow flag, then the red.
