Castillo good, not great, prospect

— -- Cuba has produced its fair share of major league stars in recent years, with players such as Yasiel Puig, Jose Abreu and Aroldis Chapman all having fantastic seasons and looking like fantasy mainstays for the next several seasons.

Here's a breakdown of why Castillo, 27, has a chance to be a quality fantasy player in the coming years, and also why it's unlikely that he reaches the level of the players mentioned above.
