Teixeira got 8/180, so 6/130 is about right. I don't know if they'll go to a 7th year.
Now the Sox don't look too bad for letting V-Mart go. Barring any major injuries, the team is pretty much set at every spot except catcher for the next 3 years (as in, they'll be guaranteed good production from every slot, assuming Kalish replaces Drew adequately).
Edit: Of course, this is assuming the Sox sign Crawford or Werth, which makes too much sense to not do.
