12 team keeper league (standard stat + holds/OBP). I can keep one of Shields or Zimmerman To staff my rotation of Hamels, Greinke, Price and Pomeranz. I can only keep one. Who's the Better keeper for the 2012 season? WHIR as always!
With only one 'n', I came in here thinking you should definitely hang onto the third baseman. As it is, go with Shields. You may feel guilty if Zimmermann lights it up this year, but at least you know what you're getting in Shields. That is, if he doesn't regress to some bad habits.
