Whether you're interested in Fantasy baseball research or just love reading about the game and the players, the Baseball Prospectus is the best, most interesting book on the market. There are general team comments which tend to focus on personal, economic and historical issues. Then come the player comments --the book is organized by league and team then by player dividing hitters from pitchers. It doesn't just write about players in the majors or top rookies, its breath of players is impressive and reason enough to buy it -- from the deep minors on up. The writing is interesting, usually insiteful; although sometimes they try to get too funny (usually about a player who's perfomance needs more analysis than humor). Still that's a minor quible. Would I use it for a fantasy baseball draft, yes (I do); although its probably more valuable in season as teams start adding players you've never heard of (the Prospectus has, don't worry). Would I read it if I weren't in a Fantasy Baseball league -- yes without a doubt. In fact, I would say the book is geared to discussing baseball as a sport more than assessing fantasy value. There are hours of reading here. One word of warning -- the stats listed in the book are NOT the actual stats, but rather translations to a "normal" league environment (they list the past 4 stat lines). This translation makes it easier to compare a player's A Ball performance with another's AAA and another's Major league stats, but it can cause some confusion on the first read. If you are looking for Fantasy Baseball books, also take a look at Shandler's Baseball Forcaster, which is probably better for draft preparation. Still, if I was buying only one baseball book, The Baseball Prospectus would be it.
