Agree with Slateman on Zimmerman sticking to first base. The Nats would rather weaken themselves at one position, perhaps only against lefties, by playing Moore in left and RZ at first, than move RZ back for a few games to left, away from his full time position for the next several years. Moore might be a better first baseman than an outfielder, but the Nats would likely use him sort of like SF used Morse last year. He'll play early and get replaced by McLouth if we have a lead. The only issue will be whether Moore would start against righties or whether the team will

with McLouth getting the bulk of time.
This may not even be an issue if Werth recovers in 2 months rather than 3 (or more). This can be a simple surgery. One of the guys on MLB network pointed out Mo had this late in his career and did not miss much time. Werth is an outfielder, so it is not like he has to make as many quick throws without proper position like an infielder. The move to left also helps. I just don't see the panic before the surgery. If they find out it is more complex than they thought once they go in, then I can see maybe making more of a move than signing a low tier FA to compete for a roster slot.
I don't think this team burns roster time for M. Taylor.
