Trades between the New York Mets and New York Yankees are rare. Negotiating trades in the major leagues can be complicated enough without the additional hurdle of both sides (in the back of their minds) trying their best to out-maneuver the other, knowing that if a mistake is made, it will remain in their backyard, haunting them for years to come.
Therefore, I can’t imagine there’s a deal to be made between the two based on the recent rumors.
The Mets are far from having an ‘excess’ of starting pitchers that would allow them to trade members of their current staff as it is.
