The Marlins are now owned by Jeffrey Loria, who purchased the team in 2002 for $158 million.
In 2012, the Marlins moved into a gleaming new ballpark, with many artistic flourishes inspired by Loria, who made his fortune as an art dealer.
As Sporting News pointed out in December, fans have been incensed by the stadium bill, Loria's apparent refusal to pour some of the revenue sharing funds he's received from other Major League Baseball teams into the Marlins roster, his selling off of top players that would've made the team more competitive and for firing Miami's long-serving television analyst for criticizing management on the air.

Kushner is the father of Jared Kushner, Ivanka's husband and Senior Advisor to the president.
Loria donated $125,000 to Trump's presidential campaign a year ago. Charles Kushner meanwhile reportedly had tried to buy into an National Basketball Association team in the last decade.
A spokesperson for Charles Kushner declined comment.

The sale requires approval and "takes months", according to Heyman. Kushner was convicted of illegal campaign contributions, witness tampering and tax evasion in 2005 and served time in federal prison.
It's not a secret that the Miami Marlins have pretty much been up for sale for some time now. The team has continued to rank near the bottom of all Major League Baseball teams in attendance despite the forecast for larger crowds once it moved into its new ballpark in 2012. The Marlins have not finished with a winning record since 2009. Loria has always been the bane of fans, unhappy with the team's repeated roster sell-offs in which it has traded such stars as Miguel Cabrera, Josh Beckett and Jose Reyes.
As for the Marlins, the team is considered by many as one on the rise.
