The free-agent dam is slowly beginning to break, as Eric Hosmer, Andrew Cashner, Jason Vargas and Tony Watson have all agreed to multi-year deals in the past five days, while Eduardo Nunez, Jaime Garcia and Chris Tillman have all come off the board on one-year pacts. J.D. Martinez, though, remains available as the top bat on the market despite a lack of obvious suitors for his services outside of the Red Sox and D-backs. Here’s the latest chatter on the slugger… The Red Sox and Martinez are now “moving close to a deal,” tweets Jon Heyman of FanRag Sports. There’s nothing finalized yet, he adds, noting that details on the pact remain unclear at this time. Earlier Updates Martinez and the Red Sox are still negotiating as of this afternoon, reports Evan Drellich of NBC Sports Boston. Chairman Tom Werner deferred questions on the matter to president of baseball operations Dave Dombrowski, Drellich writes, noting only that, “Obviously, there’s no news,” at this time. Peter Abraham of the Boston Globe, meanwhile, tweets that the door for a deal between Boston and Martinez remains open but adds that the team’s interest isn’t going to be indefinite. The Red Sox, according to Abraham, are “prepared to move on entirely or to another player” if they reach the point where they feel there’s no compromise possible with Martinez. Logan Morrison has been reported to be a possible fallback option for the Red Sox if they move on or if Martinez signs elsewhere.
