Mariners finalize 25-year lease to remain in Seattle

SEATTLE — The Seattle Mariners and Washington State Major League Baseball Stadium Public Facilities District Board have reached a final agreement on a new 25-year ballpark lease for the ballpark formerly known as Safeco Field.

The board on Monday unanimously approved the lease during their quarterly meeting.

The lease and companion non-relocation agreement ensures that the team will remain in the city for the next 25 years with options for two three-year extensions.

The lease says the Mariners are responsible for "performing all the maintenance, operations, and capital improvements and upgrades at the publicly-owned ballpark." The Mariners will pay all costs beyond the fixed contributions made by the facilities board and King County.

The Mariners are expected to announce a stadium naming rights deal in the next few weeks.
