Josef Newgarden becomes first repeat Indy 500 winner in 22 years

• Pato O'Ward second after losing lead on final lap
• Nascar's Kyle Busch finishes 18th after rain-delayed start

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 race.

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 as he did 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.
