The Seattle Mariners' wordmark logo has been a part of the baseball team's history since its inception in 1977, particularly in relation to the Seattle Mariners Primary logo. The original logo featured an italicized version of the team name 'Mariners', with a blue and green color scheme that was meant to represent both sea and sky. This iconic design has remained largely unchanged for over 40 years, although there have been some minor adjustments made throughout its lifespan.

In 2009, the Mariners unveiled their new primary logo which incorporated elements from their previous designs while also introducing a more modern look to reflect changes within Major League Baseball as well as changes within Seattle itself. The new design features bolder lettering with slight modifications to make it appear more contemporary, along with brighter colors such as navy blue and bright yellow-green that were chosen specifically because they represented both land and sea—the two key components of any great maritime city like Seattle! Additionally, this updated logo includes an image of Mount Rainier in order to pay homage to one of Washington state’s most beloved natural landmarks.

Today, the current iteration is still widely recognized by fans around the world thanks in part due its simple yet effective design which effectively captures all aspects associated with being “Mariner Proud:” strength through adversity; respect for tradition; passion for excellence; commitment towards innovation; resilience through change—all things embodied by this historic MLB franchise located on Puget Sound!
