Ice-T hit Indy to root for "my homey Marco." David Letterman vowed he would shear his Santa Claus beard if Graham Rahal won the Indianapolis 500.
Not even a dose of star power was enough to help Marco Andretti and Rahal in their bids to join their famous families in the winner's circle.
This time, something as simple as tire pressure forced Andretti off the pace and into the pits out of sequence, leaving him a lap down with a quarter of the race remaining in the 100th running of the race Sunday.
Andretti started near the back but had climbed into the top 10 before his tires began showing a reading of too much pressure. He was almost 15 mph off the pace when he was forced to pit. In more than 70 attempts, his family has only Mario Andretti's victory in 1969.
Marco Andretti finished 13th and Rahal, son of 1986 winner Bobby Rahal, was 14th.
