3. Amed Rosario, SS, Mets

A player with potentially more upside than Nimmo, but that comes with less polish, is shortstop Amed Rosario.

Rosario has consistently played above his age level everywhere he’s gone, yet he has still been able to show consistent performance.

He displays a good approach with good instincts at the plate, but still has some room for improvement.

In the field, Rosario shows great speed and range and has one of the strongest arms of any player in the Mets system.

While Rosario is still several years away from getting a Major League shot, he has all the makings of the Mets shortstop of the future at some point.
