OK I'm going to go out on some limbs here.
Limb #1: Ortiz is not renewed. It's actually possible we will take him back at reduced cost if he produces at an above average rate.
Limb #2: The Sox are going to be in a position to spend. There's going to be some money coming off the books and we'll be looking for quality replacements
Limb #3: One of Lars Anderson and Anthony Rizzo becomes our presumptive starting 1Bman of the future over the course of 2010.
Limb #4: Beltre has a great year and heads back to the market to cash in.
So with that in mind:
CATCHER:
Starter: Victor Martinez: Will be re-signed if possible. The drop-off to either Luis Exposito or Mark Wagner, or any free agent catcher not named Mauer, is significant so the Sox have every incentive to make VMart happy for a couple years.
Backup: Mark Wagner. He's got all the hallmarks of a fairly decent backup and he's not getting any younger. After 2010 it'll be big leagues or bust for him.
In AAA:
Luis Exposito (starter)
Dusty Brown (backup, here mostly because he's already on the 40-man and Lavarnway won't be ready yet, and to make sure Exposito isn't the victim of an emergency rush job)
FIRST BASE:
Starter: Derrek Lee. I think Lee is going to be available, and would be a good fit for 2 years and an option. He's a 3 time gold glover with a good approach at the plate and a Fenway friendly spray chart. If he's a FA i prefer him instantly over re-upping Beltre. I'd go for Pena, but Lee's skillset is more likely to age well.
Backup: Jeff Natale, Aaron Bates, or Ross Gload, depending on what the team feels they need out of a backup 1B. Natale would provide patience and work the count, but without much power, Bates would field well but probably not hit, and Gload would probide LHH matchup possibilities.
AAA: Lars Anderson. If he hits at all he'll be placed on the 40-man at the end of 2010 -- he might even earn a September callup
Backup: ONE of Natale and Bates. The other gets cut if he doesn't crack the roster. Given their ages and Natale's injury history he's probably the odd man out.
INFIELD:
Second Base: Pedroia
Third Base: Youkilis
Shortstop: Scutaro*
Backup: Jed Lowrie
In AAA:
Travis Denker
Tug Hulett
Ryan Khoury
Too danged little else. Any real depth problems we run into at second, third or short, we'll have to deal with from outside the system, especially since the Astros took Jimenez. this is particularly a problem at SS and 3B, neither of which we have even a replacement level backup for right now -- although maybe Hulett or Denker could serve in an emergency.
OUTFIELD:
RF: Drew*
CF: Cameron*
LF: Ellsbury
Backup: Reddick. I think Reddick starts to prove himself next year and cracks the roster officially as a backup the year after. There should be plenty of opportunities for him to get playing time with an aging Drew and an aging Cameron both pencilled in as regulars.
In AAA
Ryan Kalish: This might actually be reversed with Reddick -- Kalish could be better 4th OF material with his skillset vs. Reddick's, since Kalish adds an element of speed Reddick really doesn't.
Daniel Nava: There is literally no point in keeping this man around unless he gets a chance to crack the bench, and frankly he's earned at least a look IMHO. He's done everything that was asked of him well, destroyed the minors at every level, and has a good bench skillset, especially if the switch-hitting pans out at the big league level. He'd have to really clunk at the AAA level in 2010 for me to think he isn't at minimum very strong bench candidate.
Pitchers:
Rotation:
Lester
Beckett (will be renewed, there's no real reason we can't keep him around)
Lackey
Matsuzaka
Buchholz
Minors:
Bowden
Tazawa
One of the joys of this rotation is how simple it will be to keep it together over multiple seasons -- just re-sign Beckett and you're done.
Bullpen:
Papelbon
Delcarmen
Bard
RamRam
Richardson (LH)
Okajima (LH, we still hold arb control over him IMHO)
Doubront (Long)
Minors:
Bowden
Tazawa
Mills
Weiland
(Possibly Kelly, if he beats the door down, which he could)
Ryne Miller (underrated bullpen prospect with IMHO more potential than he gets credit for)
Fernando Cabrera (mostly cuz, iunno, he's already there)
* last year of his deal
