An uneducated guess would be a top ten prospect that is a pitcher, another top ten prospect, and a top 20 prospect. As the Boston Globe guy said, the Twins have so many holes it would be difficult for them. In a heartbeat the trade would happen if the prospects didn't include Buxton, Sano, Rosario, or Meyers. One of the prospect would have to have power hitting potential for the Marlins.
