Yankees general manager Brian Cashman said he has had no trade talks regarding Rodriguez with anyone and described the first report as "false."
That ESPN New York link, however, also says:
What began as a casual, joking conversation between New York Yankees president Randy Levine and Miami Marlins owner Jeffrey Loria about the possibility of Alex Rodriguez playing for the Marlins may develop into serious trade talks this offseason, according to a source with knowledge of the conversation.
Could it really happen? There are some obstacles:
A second source with knowledge of Rodriguez's thinking said the likely only place Rodriguez eventually would accept a trade to is Miami. Rodriguez has five years and $114 million remaining on his contract, not including milestone home run bonuses.
Ed Valentine of SB Nation New York thinks it should happen for the betterment of the Yankees:
No matter the financial cost it seems that a divorce would be best for everybody. The cost of getting rid of him, in dollars, will be exorbitant. We are already seeing what keeping a fading A-Rod the Yankees no longer believe in is costing them on the field and in the fan base.
It might have started as a "Ha, ha, get this!" joke between team executives. The more it's parsed by everyone involved, though, the more sense it seems to make for everyone involved.
