NEW YORK (AP) Marco Andretti and Graham Rahal know their rivalry is good for a sport craving attention. The two young drivers with the famous racing names are happy to talk it up heading into Sunday's Indianapolis 500.

On April 15 at Long Beach, Andretti's car launched briefly into the air and spun into a tire barrier after hitting Rahal from behind. IndyCar officials put Rahal on probation for six races, saying he was guilty of blocking and initiating avoidable contact.

Rahal's comments that day drew a rebuke on Twitter from racing great Mario Andretti, Marco's grandfather. The two cleared the air over the phone, but that won't stop the occasional jab between the two families.

Bobby Rahal, Graham's dad, won Indy in 1986. Michael Andretti, Marco's dad, settled for near-misses.
