The Marlins have discussed Mike Napoli and could get involved at the right price, a source tells Ken Rosenthal of FOX Sports (on Twitter). Napoli signing with Miami isn't likely if he has better options (link), but he's a South Florida native and he is good friends with Marlins catcher Jeff Mathis.
We recently heard that the Marlins were interested in free agent catcher Dioner Navarro (as well as pitcher Phil Hughes), but Napoli represents a much more ambitious target for Miami. While a big-name free agent like Napoli being connected to the Marlins will clearly be met with skepticism (and rightfully so), it's worth pointing out that they were very much in the mix for Jose Dariel Abreu before he signed with the White Sox. That pursuit, at the very least, indicates that the Fish may have some willingness to spend on a first baseman to pair with Giancarlo Stanton in the middle of their lineup.
