After the season the Elias Sports Bureau will take all players over the 2010-11 period, divide them into five groups for each league, and rank them based on various statistics. Then each player will be labeled a Type A, B, or none. Those designations and the possible accompanying arbitration offers determine draft pick compensation (click here for a refresher).
Eddie Bajek has reverse-engineered the Elias rankings, and he's providing that information exclusively at MLB Trade Rumors. Here's a look at how the players rank for the period beginning with the 2010 season running through June 25th, 2011. The Google spreadsheet below has separate tabs for each position group and can also be found directly here.
