 $3.3 billion ballpark to replace Tropicana Field. The ballpark would be the beginning of what is expected to be a $6.5 billion public and private investment project on the 65-acre site. The Rays have committed to paying $700 million plus towards the stadium, while Pinellas County, where St. Petersburg is located, is set to vote later this month on the final $300 million in tax revenue.
