Major League Baseball granted free agency to 537 minor league players on Nov. 2, five days after Game Seven of the World Series heralded the end of the 2011 season. The number of players in this year's free agent class is consistent with totals from 2010 (533 players) and ’09 (536). You can find past free agent classes archived on our blog.

Update: Sort all 600-plus free agents by position, organization or level with out new Minor League Free Agent Tracker. (Nov. 7)

Typically, MLB deems a minor league player a free agent if one of two conditions is met. (A minor league player is one not on a 40-man roster.) In many cases, his initial signing team simply has used all six of its contract renewals. We can illustrate this concept using the example of Orioles 2005 third-rounder Brandon Erbe, who signed weeks after that draft. Baltimore exercised contract renewals for Erbe for the maximum of six years—for the 2006, ’07, ’08, ’09, ’10 and ’11 seasons. To retain him for 2012 they would have had to add him to the 40-man roster—or in his case re-add him to the roster.

In other cases, a player's one-year minor league contract, signed either during the 2011 season or in the offseason, has expired. These players are no longer bound to their signing organization with contract renewals. They simply go year to year on one-year pacts. To cite examples, the Nationals signed veterans Matt Antonelli and Michael Aubrey to such deals last offseason.
