The Elias rankings are out for major league players. They are used to determine whether a player is considered "A" or "B". While most players listed are not free agents right now, this of course has been used to determine what kind of draft compensation a team can expect if they lose a player to free agency.
Players' performance over the past two seasons are used to rank them. I'm sure there will be some questions about the rankings, but it's certainly interesting.
As far as our Oakland Athletics go, only Swish is rated "A" among outfielders, first basemen, and DH's. None are "type A" for 2B, SS or 3B...Ellis is a "B"...Haren and Blanton are "A" starters, while Street and Embree are "A" relievers. Street is considered the third best reliever in the AL, behind only JJ Putz and Joe Nathan.
