On opening Night 1990, the Mariner Moose became the first mascot in team history. The Moose was selected from over 2,500 entries submitted by children 14 and under across the Pacific Northwest.

Located in Center Field on the Main Concourse, the Moose Den provides our younger fans an opportunity to meet the Mariner Moose periodically during each Mariners home game. Photo opportunities are provided for all guests.
