One of the more difficult players to analyze right now is Giants first base prospect Angel Villalona. He's got two huge strengths: enormous raw power, and age-relative-to-league, since he was just 17 for most of last year in full season ball (assuming that his listed age is correct). He also has a huge weakness: his strike zone judgment is awful. He also lacks speed and will have to work hard to maintain his physical condition.
So, how do we balance this out? Is his youth more important than the awful strike zone judgment? I gave him a Grade B in the book, a compromise between Grade A potential and Grade C refinement. What is your take on Villalona, and how do you see his career developing?
