Brazilian Helio Castroneves became a four-time Indianapolis 500 winner Sunday in front of the largest crowd since the start of the pandemic.

To celebrate he jumped out of his car and scaled the fence at Indianapolis Motor Speedway in front of his adoring fans.

Castroneves won his third 500 in 2009 and has been chasing win No. 4 ever since.

He joined A.J. Foyt, Al Unser Sr., and his former mentor Rick Mears, at Team Penske as the only four-time winners of "The Greatest Spectacle in Racing." Mears was the last driver to join the exclusive club of four-time Indianapolis 500 winners in 1991.

At age 46, in his first season no longer driving for Roger Penske, he held off Alex Palou to win the 105th running of the race in front of 135,000 fans – the most at any sports event in the world since the pandemic began 18 months ago. The number represented 40% of the speedway’s capacity and was agreed upon by health officials.
