Here's a set of rankings showing the top 10 prospects at each position, including separate lists for right- and left-handed pitchers. I've combined second basemen and shortstops due to the intrinsic lack of second-base prospects in the minors; second basemen are identified by (2b) after their team affiliations. All positions are current, rather than projected, although if a player is likely to have to move off of the position it is taken into account in the rankings.
