Attached here are the Batter Minor League Projections (MLPs) from the 2007 minor league seasons (for players with 200+ AB+BB).  In one sense, this can be viewed as a list of the 100 most-promising minor-league seasons from 2007, though some of the low-AB seasons are less reason for optimism than worse rate stats over more AB.

Using aging curves, modified by a variety of factors, Major League Projections (MLPs) attempt to project a given set of data compiled in a given minor-league season out to the “prime years” of a player's major-league career.  To me, the easiest way of thinking about these target values is an average of the “middle three” seasons from ages 26-30, meaning to discard the high and low outliers from this grouping.  Various factors are taken into account, such as park factors, BABIP, and other stats which can influence how much growing a player has left before age starts him into a decline phase.  Obviously, MLPs are geared toward the mythical “neutral park”, since a lot of things can change between the time a guy plays in A ball and when he's in his prime in the majors.

And others - as with MLB players as well – have wild fluctuations, though with the adjustments for BABIP, some of the fluky batting-average variations are smoothed out.  Obviously, this system also assumes that players will follow a typical growth pattern, based on their previous stats, and not pull a Hanley Ramirez explosion nor a Sean Burroughs collapse. 

Note: SB and CS numbers are NOT projected, rather they are simply the minor-league totals.
