Dixon won by less than half a second from Rahal Letterman Lanigan Racing’s Graham Rahal and Arrow McLaren’s Pato O’Ward.
Title contenders Alex Palou (Chip Ganassi Racing) and Josef Newgarden (Team Penske) endured a wild first lap in which both made contact with Marcus Armstrong, with Newgarden losing a lap as Palou, typically, escaped relatively unscathed and finished seventh. Newgarden trailed home in 25th.
