Relievers On Boston’s Radar

4:23pm: The Red Sox are having ongoing discussions with Dan Wheeler about a possible deal, according to Alex Speier of WEEI.com. One of Speier's sources is optimistic about the negotiations.

1:16pm: The Red Sox liked Matt Guerrier well enough to offer him a two-year deal, but the Dodgers offered a third guaranteed year and the right-hander has agreed to play for Los Angeles. The Red Sox will have to move on to other targets as they look to round out their 'pen. Nick Cafardo of the Boston Globe has the details on what he says is the biggest challenge of the offseason for GM Theo Epstein.

Two former Twins, right-hander Jesse Crain and left-hander Brian Fuentes are the team’s priorities now. The Red Sox are also considering trades and would “love” to reacquire Justin Masterson, according to Cafardo. The Indians have been reluctant to part with Masterson, whom they acquired in the 2009 Victor Martinez trade.

There are a number of alternatives for Epstein to pursue, including Indians relievers Joe Smith and Rafael Perez, who “could be on Boston’s radar.” The A’s are likely willing to listen on their relievers and the Mariners would listen on David Aardsma, Cafardo writes.
