I think that from your list. Rasmus and Gordon aren't going anywhere. If they are inexpensive, they will stay put where they are comfortable with. Parra though will go to the highest bidder which will still be inexpensive.
Chen and Leake I can see moving. Although I don't know if Chen is an upgrade to what we have now. Leake at least has that low WHIP, but always am hesitant on a NL pitcher going to the AL with non dominating numbers. Gallardo is probably going to move, but again, not sure if he's an upgrade. His WHIP is awefully high.
Zobrist is going to get paid. I don't think he will be inexpensive. Also doesn't help he plays for KC which like Gordon, KC has money to spend.
Kendrick is a possibility. But not many players go back to teams that traded them. Would be nice if he did though.
Murphy is also a possibility. Mets may blow their wad on Cespedes.
