Andy Seiler and Pat Hickey recently posted their top 50 over at MLB Bonus baby.
I am currently working on mine, but I don't have enough info on some of the high school guys yet to have a firm ranking. I'd like to be confident when I post it and I'm not there yet. If you want to know some names check out their site and my link for 2011 and 2012 draft names to watch. Keep an eye out for my top 50-100. I will post a link on the right when I get it posted.
