In wet and rainy conditions, Simon Pagenaud won the IndyCar Grand Prix for the third time, and matching Will Power's accomplishment from a year earlier, swept the month of May by winning the Indianapolis 500 two weeks later. Pagenaud charged from 6th place to 1st over the final 18 laps. With two laps to go, race leader Scott Dixon led Pagenaud as they approached the end of the Hulman Boulevard backstretch. Dixon slid a little wide in turn 7, and Pagenaud took the lead in turns 8-9. Pagenaud pulled out to a 2-second victory.
