M1 Racing's Nicolas Costa made another stirring charge during Pro Mazda competition Saturday at the Indianapolis Motor Speedway. Coming from the 15th starting position, he had just taken second following a restart with six laps to go in the 20-lap race when there was contact with the driver he'd just passed. Costa ended up backwards in the wall entering Turn 1 for a 16th-place finish in round six of the series, which is presented by Cooper Tires.
