Thanks to Dave Mackey in the post below who pointed out new assignments as per the Mets.com roster. I'll rap more about these later, but here's the pertinent info. Hats off to outfielding prospect Kirk Nieuwenhuis, with the highest digits assigned so far. 

Of interest: Alex Cora moving to 13 and new catcher Chris Coste taking over 3.
