The Mariners have extended their contract with Triple-A Tacoma of the Pacific Coast League through at least the 2014 season.
Tacoma announced a four-year extension of the player-development contract on Tuesday.
Mariners general manager Jack Zduriencik says he values the convenience of the Triple-A team being so close to Seattle.
Tacoma has been affiliated with the Mariners since 1995.
