After the season the Elias Sports Bureau will take all players over the 2009-10 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 2009 season running through July 3rd, 2010. The Google spreadsheet below has separate tabs for each position group. The players have about three more months to change these rankings. You can also go directly to the Google spreadsheet here, download the rankings in Excel here, and view a PDF here.
