The Boston Herald's Scott Lauber reports Mike Napoli is scheduled to visit with the Mariners.
This is just confirmation on what ESPN's Jim Bowden reported Thursday. Napoli received a three-year offer from the Red Sox but is seeking a four-year contract. The extent of the Mariners interest, or if they'd be willing to go four years, isn't yet known. Napoli would primarily be used as a catcher in Seattle.
