Seth Gruen of the Northwest Herald says that the Seattle Mariners are interested in acquiring A.J. Pierzynski. Gruen also adds the Texas Rangers are interested in the catcher as reported by Mark Gonzales of the Chicago Tribune last week.

Gruen adds that Pierzynski will continue to become more attractive to teams looking for a starting catcher as his left-handed bat heats up.

A potential hangup for any trade involving Pierzynski would be the catcher’s 10-and-five rights (10 years in the majors, five years with the same team), which entitle him to veto any trade.

His rights will become active June 14. If the Sox don’t close in on the division lead quickly, Pierzynski could be the first to go.
