Ryan Hunter-Reay won his first IndyCar race since 2015, prevailing at Belle Isle after teammate Alexander Rossi slid off the track at a turn with about seven laps to go.
Rossi, the pole winner, was struggling to hold off Hunter-Reay before the mishap at a right turn on lap 64 of 70. From there, it was smooth sailing for Hunter-Reay on the 2.35-mile street course. He finished more than 11 seconds ahead of second-place Will Power.
Ed Jones finished third, followed by Scott Dixon. Rossi fell to 12th and dropped out of the series points lead.
