Following a four-hour rain delay, the IndyCar blue ribband event boiled down to a dramatic showdown between Josef Newgarden and Pato O’Ward, with the Mexican taking the lead into Turn 1 on the 200th and final lap.
But Team Penske's Newgarden wasn't finished and reclaimed the head with a daring outside move at Turn 3 before crossing the line to become the first back-to-back 500 winner since Helio Castroneves in 2002.
