Legendary race car driver Al Unser Sr. died Thursday at his home in Chama, New Mexico, the president of the Indianapolis Motor Speedway (IMS) announced.
He was 82 years old and had been battling cancer for the past 17 years, according to the racing league. Unser won the Indianapolis 500 four times, one of only four racers in history to do so. IMS President J. Douglas Boles said Unser also set a record for the most laps led in the Indy 500.
