The players are Shortstop Amed Rosario, Pitchers Marcos Molina, Chris Flexen, Catcher Tomas Nido, and Outfielder Wuilmer Becerra.
Of those, the most highly regarded is the 20 year old Rosario, who is the Mets number one prospect. Rosario signed as an international free agent in July 2012 for $1.75 million.
He participated in the 2016 MLB All Star Futures Game. During this season, he hit .324 with 42 Extra-base hits, 71 Runs Batted In, and 19 Stolen Bases split between St. Lucie and Binghamton.
Marcos Molina recently came back from Tommy John rehab and pitched fairly well in the Arizona Fall League.
