The Miami Marlins are now sitting at 32-28 and the trade deadline will be here before we know it, so the question remains, do these three players remain with Miami. Could the three players be used as trade bait, are they worth anything in the market, and would Marlins GM Kim Ng find a replacement for each of them, if possible. The Marlins are in sole possession of second place in the National League East and the final wild card spot for the playoffs, so they will be buyers at the deadline barring some major change.
