After taking the lead from polesitter and Penske team-mate Will Power in the early stages, Newgarden dominated the 250 lap race held on the 0.804 mile oval, that was punctuated by a series of cautions.
Having survived brief contact with Indy 500 winner Marcus Ericsson, Newgarden went on to take the win from Arrow McLaren's Pato O'Ward and Power.
