I just got BA's prospect handbook and McKamey's Minor League Baseball Analyst. I haven't even opened BA's yet but McKamey's is really impressive. Does a great job of quantifying the scouting aspect by rating a players tools on a 1-5 "+" scale, a paragraph on every player, plus a lot of useful statistics(AVG/OBP/SLG/OPS, BB%, Contact%, XBH rate, RC/G, and others). For pitchers, he grades each of their pitches on the 1-5 scale, with radar ranges when he can get them. Stats include ERA, WHIP, Batters Faced/Game, OBA, H%, S%, xERA, and several others. He also projects each players role, and estimates their MLB debut.
