I might have overlooked someone, I’ve found only two current Yankees listed on the remaining World Baseball Classic rosters. 
Robinson Cano — Dominican Republic
Francisco Cervelli — Italy
There are plenty of former Yankees in the mix. Russell Martin is on the Canadian roster, Melky Cabrera is on the Dominican Republic roster, Jose Molina is on Puerto Rico’s roster and Andruw Jones is on the Netherlands’ roster. Team Mexico has Luis Ayala, Alfredo Aceves, Ramiro Pena and Karim Garcia.
