FRIDAY: The Mariners are definitely in on Napoli and the Rangers and Red Sox are also involved, Jon Heyman of CBSSports.com reports (on Twitter).

THURSDAY: The Red Sox and Mariners continue pursuing free agent catcher Mike Napoli, Jim Bowden of ESPN.com and MLB Network Radio reports (on Twitter). Napoli is holding out for a fourth guaranteed year from Boston, and he's meeting with the Mariners, who might be willing to commit for the extra year.

The Mariners, Red Sox and Yankees are among the teams that have already been linked to Napoli this offseason. The 31-year-old ranked 14th on MLBTR’s top 50 free agent list earlier in the month. He did not obtain a qualifying offer from the Rangers, which means he won’t be linked to draft pick compensation. In 417 plate appearances as a catcher, first baseman and designated hitter, Napoli posted a .227/.343/.469 line with 24 home runs this past season. He is a client of Paragon Sports International.
