Catcher Dioner Navarro is "moving to resolution" with a team, according to Peter Gammons of the MLB Network (on Twitter). Gammons doesn't have the name of the front-runner yet, but he adds that the Red Sox are not in pursuit.
Navarro, who turns 30 in February, enjoyed a strong rebound campaign with the Cubs in 2013, batting .300/.365/.492 with 13 home runs in 89 games (266 plate appearances). The Marlins are the main team to have expressed interest in Navarro so far, though the Red Sox did apparently express some interest as a fallback option should their top targets fall through.
The Blue Jays have been said to be in the market for a catcher, as have the Twins, in light of the news that Joe Mauer's days behind the plate are done and he will be a first baseman going forward. The Rays don't figure to be in the mix after reaching an agreement with Jose Molina over the weekend.
