SAN DIEGO -- The Red Sox and Phillies have had discussions this offseason about a deal that would send left-hander Antonio Bastardo to Boston in exchange for a package involving infield prospect Sean Coyle, according to a major-league source with knowledge of the situation. It is unclear if those talks are still progressing, though the teams are known to be in contact due to Boston's continued interest in both Bastardo and Cole Hamels.

Bastardo, who drew significant interest before the non-waiver trade deadline, has been thought of as a trade candidate this winter as the Phillies try to rebuild their roster. The Red Sox are lacking left-handed relief after the departure of Craig Breslow to free agency, and are known to be poking around the free-agent market for southpaws as well.

Coyle, who recently switched representation, is currently ranked by SoxProspects.com as the team's fourteenth best prospect, and is thought of as trade bait due to the Red Sox' glut of young infielders. The team is also known to be shopping Deven Marrero, and Garin Cecchini may become available as well.
