According to MASN, the contract is one year for $8 million.  Zuckerman has the signing but not the amount. 

I would rather have had Lee for one year than LaRoche for three; let's hope that the scuttlebutt is true that the Nats are the only team left in the hunt.  A two year deal for LaRoche would be fine, perhaps a three year deal with a team option for a nominal buyout of the 3rd year.  Personally I'd prefer to have LaRoche at 1b and have Morse as a 400AB swing guy platooning with Bernadina in LF and also spelling Werth in RF and LaRoche at 1b.  That would also give the team some real thump from the bench with Morse from the right side and Stairs from the left.  But they need to sign LaRoche first.
