How about dropping Theriot? Wieters is supposed to be ridiculously good, especially in a keeper but there are a lot of folks out there who think he'll step right in this season and do some damage. I wouldn't recommend losing Sandoval or Iannetta... you'd have a surplus at catcher, but you can always trade it later for speed or a back-up infielder if you miss Theriot.
Check out the thread on Wieters in the 2009 Predictions forum & also note he's 11-for-25 so far in Spring Training...
