The South Florida Sun-Sentinel reports a memo from Miami-Dade County Manager George Burgess to county commissioners said the public financing needed to build a new stadium is out of their reach.
The Marlins and local officials are in discussions on building a 38,000-seat, retractable-roof park, but talks are stalling out.
County officials are trying to shore up the $45 million gap in funding that would keep the Marlins in south Florida.
The state Legislature didn't approve a tax break for the building and Miami officials said they have no more money to give to the project.
Burgess is working on finding other funding and will report to the county commission on Sept. 22.
