"At this point, less than a month before pitchers and catchers report to spring training, the Red Sox are more likely to address their starting rotation needs through free agency than via a trade, according to a major league source.

One potential solution: Edwin Jackson.

Jackson, a free agent right-hander, is mulling "a variety of options," agent Scott Boras said by phone yesterday, and may reach a decision by week's end.

Boras declined to confirm a tweet from ESPN.com's Jim Bowden that the Sox have made an offer, but indications are Jackson may be amenable to a one-year contract after initially seeking a multiyear deal."
