This is a tough question really. On a 4 man bench we need a backup C (Thole), a backup CF (Gose), and a backup MIF. This leaves you room for two platoon bats. I think Reimold is a nice platoon bat (for Lind) / bat off the bench. He get the spot for me.
I don't see how you avoid loosing Francisco and maybe even Valencia (which won't happen). The only way you can not loose one or both of those guys is leave your team with no backup at CF of MIF. If one of those guys gets hurt, you play out that game and move a move for the next game. Its not ideal, but it might have to happen.
For what its worth my bench is;
Thole, Reimold, Tolleson, and Valencia (just because I know he won't be sent down).
Starting Roster is; Reyes, Cabrera, Bautista, Lind, EE, Navarro, Lawrie, Rasmus, Goins or Kawa
Sent down; Francisco, Gose, Goins or Kawa
