Keeper help for 2013

[Setzer]

I'm in a H2H Points league and we get 4 keepers. Below are a list of player I'm considering keeping. I'll note if they were drafted or undrafted.

Mike Trout(24th)
James Shields(20th)
Cole Hamels(5th)
Craig Kimbrel(16th)
Chris Sale(undrafted)
Kris Medlen(undrafted)

Right now I'm definitely thinking Trout, Sale and Kimbrel but undecided on the 4th. Any suggestions? Which 4 would you pick?

Kind of hard to not keep Shields with that value. I would attempt to redraft Medlan.
