So exactly how much time does he need in Rochester? If he can hit in Triple A but not yet in the big leagues he needs to learn in MLB. I don't see much benefit to honing his fielding in the minors. Ground balls are ground balls. I think he will be up by June. Unless Escobar finds whatever he was on last year.
Psychologically, though, booted ground balls hit by the Syracuse Mets aren't the same as booted ground balls hit by the OG Mets.
