Three pitchers and an outfielder. (Sounds like a bad reality show on the MLB Network.)
Tony Armas Jr. will be returning to the Mets organization and Matt DeSalvo, Valerio de los Santos and Bobby Kielty will be the newcomers to the the team.
I like Armas Jr., as he's versatile to start or be the long-man if needed.
Nothing really important to note here, only that Kielty looks a heck of a lot like the bad guy from The Incredibles.
