Andretti Sports Marketing will only assist with ’13 Grand Prix of Baltimore

Andretti Sports Marketing has signed a deal with Grand Prix of Baltimore organizers Race On LLC "to return for the 2013 event."

Andretti will "play a smaller role" for next year's race, "leaving much of the preparations" to Race On. The promoter will handle race-day operations and national sponsorship sales next year after handling "most organizational aspects" of this year's event. BIZJOURNALS.com
