There have been a number of Japanese players who will allegedly be posted this winter, and a few Cuban players have defected and will be free agents. Many of these players were not on previous top 50 free agent lists, but they have cracked this new list.
Players have begun to sign with new teams, which also has led to some other changes in the top 50 MLB free agents that are available.
Each one of these players will be sought after this winter by a number of teams. The list is very top heavy, but there are a number of good free agents who are on the market. These players will all help improve whatever team signs them.
