The Marlins have selected the Bicentennial Park in downtown Miami as their site for a new ballpark. The team wil dedicate the next 45-60 days to discuss the ballpark with the city. If it appears after that period that Miami is not a viable option, then Fort Lauderdale will be reconsidered. In addition, the Marlins named HOK as design architect and architect of record. The announcements were made by Marlins Chairman John W. Henry. New Ballpark Page.
