Veteran catcher Kelly Shoppach is in Seattle meeting with Mariners officials and is scheduled to take a physical on Wednesday, according to a baseball source, as the club continues looking to add depth behind the plate. The deal will pay Shoppach a base salary of $1.5 million with an opportunity to earn an additional $500,000 in incentives, the source said. Shoppach, 32, has played with the Red Sox, Indians, Rays and Mets during his eight years in the Majors, posting a .226 batting average with 67 home runs and 207 RBIs in 536 games. The Mariners recently sent his backup, John Jaso, to Oakland in a three-way trade that brought Michael Morse from Washington to Seattle. Montero is currently the only catcher on the 40-man roster, but the Mariners signed veteran Ronny Paulino to a Minor League deal last seek and have also invited Minor Leaguers Mike Zunino, John Hicks and Jesus Sucre to their Major League camp, which starts Feb. The right-handed-hitting backstop split last year between the Red Sox and Mets, hitting .250 with five homers and 17 RBIs in 158 at-bats with Boston before being traded in mid-August.
