According to FOX Sports' Ken Rosenthal pursuing a trade for Phillies left-hander Cole Hamels is likely the "Plan B" for the Red Sox if they are unable to sign free agent left-hander Jon Lester.

The market for Hamels could become clearer once Lester lands somewhere, though it’s still up-in-the-air as to whether the Phillies asking price will be met for Hamels this winter.  However, in the report he says its "not out of the question"  that both Hamels and Lester could wind up on the Red Sox roster.

The 30-year-old southpaw is owed $96 million over the next four seasons with a $24 million option for 2019, which is a very solid value in this market.

USA Today's Bob Nightengale reported about two weeks ago that the Red Sox "have had the most serious talks" with the Phillies regarding a trade for Hamels.  Furthermore, Nick Cafardo of the Boston Globe reported a few weeks ago that the Red Sox had already rejected a couple of trade proposals from the Phillies, but the dynamic has changed now that the Sox have signed both Hanley Ramirez and Pablo Sandoval.

Something to keep an eye on...
