Fake teams has released the names of the Marlins you will need to include on your fantasy team next season.
Fantasy Baseball: Top 5 Florida Marlins for 2010
You will notice that Chris Coghlan is not on the list. I assume that has to do with him playing outfield, should the Marlins trade Uggla and Coghlan moves to second, get him on your team immediately. Of course that assumes that he is still available in your league and not suffering from a sophomore slump, which I don't think he will.
