St. Louis, San Francisco and Boston might not be at the top of Giancarlo Stanton’s destination wish list. But the alternative — remaining with the Marlins as the lone star on a stripped-down team through a slow and potentially agonizing rebuild — might be even less appealing to him. It’s a choice that could force Stanton’s hand if the Marlins work out acceptable trade proposals with teams that are less desirable to him than others. According to two sources with knowledge of discussions, the Marlins informed Stanton in October that if he refused to waive his no-trade rights and accept a trade, he would remain a Marlin and team officials would look to trade off other top players to reduce payroll. While it wasn’t presented to Stanton as an ultimatum, one source said, it shows that the Marlins aren’t without leverage in their efforts to deal Stanton and relieve them of the financial burden he brings. Stanton has said he doesn’t wish to be part of a rebuild. Shedding the $25 million that Stanton is set to make in 2018 — not to mention the $295 million owed to him over the remainder of his contract — would go a long way toward helping the Marlins reach their $90 million target payroll next season. They would also like to trade infielders Dee Gordon and Martin Prado to help satisfy that goal.
