INDIANAPOLIS (AP) — Josef Newgarden put his cheating scandal behind him to become the first back-to-back winner of the Indianapolis 500 since Helio Castroneves 22 years ago and give Roger Penske a record-extending 20th win in “The Greatest Spectacle in Racing.” The Tennessean passed Pato O’Ward on the final lap of Sunday’s rain-delayed race to become the first driver to win consecutive 500s since Castroneves did it for Penske in 2001 and 2002. And just like last year, Newgarden stopped his Chevrolet-powered car on the track and climbed through a hole in the fence to celebrate with fans in the grandstands. O’Ward slumped his head over his steering wheel in bitter disappointment. He was trying to become the first Mexican in 108 runnings to win the Indy 500.
