Baseball America does such a fantastic job of filling the offseason with baseball prospects and prognostication. They've kicked it off with the Top 20 from Arizona (I recognize the offseason is still a ways off).

The Gigantes had three players listed;

7. Waldis Joaquin, rhp, Giants (Dominican Rep)
   
10. Shairon Martis, rhp, Giants (Curacao)
    
11. Sharlon Schoop, ss, Giants  (Curacao)
