Jacoby Ellsbury is under control of the Red Sox for one more season, but his future with the franchise may be decided this winter.

A multi-year contract will be considered, but his value is hard to determine. Ellsbury has an MVP-level season in 2011, but injuries derailed his 2010 and 2012 campaigns.

Boston's best bet may be to trade Ellsbury, who has more value to a team on the verge of winning a championship. The starting rotation has been the team's weakness for two years running and the young center fielder could be used as a trade chip.

The Giants and Nationals may be likely trade partners due to their deep pitching staffs.
