The exclusive club of players who have suited up for the New York Mets and New York Yankees is quite extensive. The newest member of this group is Dellin Betances, the longtime Yankees reliever who will suit up for the Mets in 2020.
For years, Betances has been one of the best relievers in the game. He has never known another big league team aside from the Yankees. In 2020, he’ll finally get a taste when he switches boroughs.
After the 2010 campaign, the Mets were on the opposite side of a switch like this.
