During the season-long celebration former Mariners players will be welcomed back to Seattle for special appearances and promotions at Safeco Field. Details of the special events will be announced before the start of the season.
A logo has been created to commemorate the 40th Anniversary. It will be worn on the right sleeve of Mariners home and road jerseys during the 2017 season. The logo features Mount Rainier and the Seattle skyline with the Mariners trademark nautical compass rose superimposed on the number 40.
The patch will be in two color schemes -- with navy as the predominant color; and a version in royal blue and gold for the Sunday alternate uniforms. The logo will also appear on the outfield wall at Safeco Field.
Other patches the Mariners have worn on their uniforms over the years have included the All-Star Game (2001), the team's 30th Anniversary (2007), a tribute to Dave Niehaus (2011), the team's 35th Anniversary season (2012), an MLB-wide tribute to the Negro Leagues in 1985, and commemoration of the 125th Anniversary of Major League Baseball in 1994.
Authentic home and road jerseys featuring the 40th Anniversary patch are scheduled to be available in Seattle Mariners Team Stores next week. Alternate jerseys, along with other apparel featuring the logo will be in stores in January. Seattle Mariners Team Stores are located at Safeco Field, at Fourth & Stewart in downtown Seattle, Bellevue Square, Alderwood Mall and Southcenter Mall.
