According to WEEI.com, Boston declined Takashi Saito's $6-million club option for 2010, ultimately resulting in Saito declaring himself a free agent.  Regardless, it is believed that the two sides may still negotiate a deal for 2010.

Miguel Gonzalez was selected in the 2008 Rule 5 Draft from the LA Angels.  He spent the entire 2009 season on the DL after March 2009 Tommy John Surgery.  As such, the Sox will need to keep him on the active roster for an aggregate of ninety days in 2010 or they must return him to the Angels.  He'll likely remain in the Sox organization until he returns to the mound, at which point he may see some rehab time in the minors. However, he'll make a major league salary for whatever time he rehabs next season, so don't expect the Sox to give him a long rope.  

Victor Martinez has a $7.5-million club option for 2010 that the Sox are expected to exercise.

Alex Gonzalez has a $6-million mutual option for 2010.  It is believed that Gonzalez will return to Boston next season, but there is some speculation that the two sides may attempt to restructure a new deal first.  If the Sox don't bring Gonzalez back, a long-term Type A free agent signing is unlikely.  In that case, Adam Everett and Jack Wilson could be potential targets. Hanley Ramirez is also an outside possibility as a trade target, but would come at a hefty price.

Jason Bay filed for free agency on November 5.  He has indicated that Boston is one of the few teams on his radar.  If Boston is unable to sign Bay, other free agent outfielders that the Sox might target include Matt Holliday, Johnny Damon, and Gary Sheffield.

George Kottaras has just 1 year and 21 days of major league service time, meaning Boston has the option of bringing him back as the backup catcher for the major league minimum in 2010.  However, he is out of options and thus can't be assigned to the minors without clearing waivers.  Given that Kottaras threw out only 16.1% of would-be base stealers in 2009, the Sox may look for a more defensive-minded backstop for the 2010 season.

Casey Kotchman will be arbitration-eligible this off-season, meaning he will likely receive a raise from his $2.89-million salary from 2009. The problem for Kotchman is that there doesn't appear to be a lot of space for him on the 2010 roster unless the Sox anoint him the starter at first base.  Even if Boston doesn't sign a corner infield bat this off-season, there will still be a crunch for playing time at first and third base next year between Kevin Youkilis, Victor Martinez, Mike Lowell, and even David Ortiz when the Sox play in NL parks. As Kotchman is good enough to start for a mid-market team, and his contract is still relatively reasonable, he may be a candidate to be traded this off-season.  Otherwise, he'll be an excellent bench option for the 2010 club.
