Scott Dixon scored Ganassi’s first victory of 2018 in the opening race of the ‘Dual at Detroit’.
Hunter-Reay came home third ahead of team mates Alexander Rossi and Marco Andretti, who changed places in the closing stages after a muscular pass by Rossi on the outside of turn three.
With Takuma Sato fifth ahead of Ed Jones the top six places were commanded by Honda-powered cars at a race sponsored by rival Chevrolet. Will Power was their top finisher in seventh. Robert Wickens, Josef Newgarden and Spencer Pigot completed the top 10.
Graham Rahal, who won both races in last year’s double header, crashed out heavily at turn 12 after hitting the inside kerb hard. A second caution period was triggered when Charlie Kimball ran into Santino Ferrucci, dumping the newcomer into the barriers at turn seven.
