From what I can tell, the Sox will have somewhere around $30 million to spend this offseason with Ortiz having his $12.5 option picked up. My numbers may be off a bit (exact salaries are difficult to determine sometimes). What we haven't discussed--or what I haven't noticed--is that that doesn't actually give them a ton of flexability. They need a 3B, a C, possibly another OF, and probably at least a few decent bullpen options.
They could hand a starting job to Kalish next year, but it seems a tad risky to me. I actually think guys like Nava, Reddick and Kalish are all ready to contribute at the backup level, so OF might not be highest priority; at the same time, Werth and Crawford probably offer the most offensive "rejuvenation" and I think Crawford in particular gives the team flexability if they want to look at moving Kalish or Ellsbury elsewhere.
Now that they have picked up the expensive Ortiz option, I am looking for them to sign one of Crawford, Werth, Martinez or Beltre, add a catcher (Miguel Olivo, Mike Napoli?) and sign a few bullpen arms. At that point I expect them to more or less stop, except for the trade market where I hope they will be aggressive.
