Rotoworld released their list of the top ten prospects for each club in the NL East. For the Marlins they actually include two position players, quite a novelty from previous lists. Rotoworld also included the next five but didn't do write up about them.
Rotoworld's Top 10 Prospects - NL East
As long as we are on the subject of fantasy baseball, Eric, our friend at Fake Teams, needs some help. He is trying to determine who are/is the possible sleepers for the Marlins. If you have an opinion on which nonstarter will get 200-350 AB, he would like to hear it. Either leave your comment at his site or in this thread, since I'm sure he will find it.
