Billy Hamilton is incredibly fast. And his plate approach is a little bit better than Yorman's is. With that said, he is also two years older. Projection wise, I don't think its really close in terms of offense. Billy Hamilton isn't going to hit for power. Yorman Rodriguez has above average raw power. Average wise, I don't think Hamilton has an advantage either. Both project to be good defenders.
I have been saying the last two weeks or so since Top 100's have started coming out that the pendulum has swung a little too far towards Billy Hamilton in terms of how good of a prospect that he is. Some people fall in love with speed too much and I think that is what we are seeing here. Speed is a complimentary skill, not a main skill. It can help out your other skills some (turning a few singles into doubles and a few doubles into triples as well as a few outs into singles), but overall bat on ball and plate discipline mean immensely more than speed. Hamilton is solid with the bat, don't get me wrong. But if he doesn't hit some HR's, and there is some concern that he might not be able to hit more than a few, what is his upside at the plate?
