FILE - In this May 24, 1987, file photo, Al Unser raises four fingers in front of the Borg-Warner trophy after winning his fourth Indy 500 race at the Indianapolis Motor Speedway in Indianapolis, Ind. Long before he won the Indianapolis 500, Al Unser was an up-and-coming 25-year-old sprint car driver who had showed up at Indianapolis Motor Speedway to watch his older brother try to qualify. Unser still remembers the feeling of awe when he drove through the tunnel beneath the track. (AP Photo/Mike Conroy, File)
