To honor their Negro leagues predecessors, the Mariners will have a new look for Sunday home games this season when they don the black-and-white uniforms of the Seattle Steelheads.
The Mariners have periodically worn Steelheads uniforms in the past — first in 1995, and most recently in 2023 — but Saturday’s announcement represents the team’s first commitment to wear them on a regular basis.
The Mariners are the first MLB team to feature a Negro leagues uniform as part of the club’s standard uniform rotation.
The Steelheads-inspired look will replace the cream-colored Sunday uniforms the Mariners wore for home games starting in 2015.
First baseman Josh Naylor unveiled the Steelheads uniform on Saturday during the Mariners' FanFest event at T-Mobile Park
That's one of the coolest uniforms I've ever worn," Naylor said. "This is so cool. Having the privilege of wearing it is, it's awesome."
When he showed up at the park Saturday morning, Naylor was not expecting to play the part of a fashion model, but he gladly showed off the new look before an announced crowd of 12,500.
In full uniform, Naylor popped out of the home dugout with strobe lights and a smoke machine going off around him.
The Steelheads played one season in Seattle, at Sick's Stadium in 1946, as part of the West Coast Negro Baseball League.
"The history behind it is beautiful," Naylor said. "And to represent those who wore it is, it's honorable.
As part of Saturday’s unveiling, the Mariners also announced they have created the Steelheads Community Fund with a $500,000 commitment in support of local Black-led baseball and softball organizations and community initiatives.
“We are proud to honor our game’s history and invest in the future of our community with Steelheads Sundays at T-Mobile Park,” Kevin Martinez, the Mariners president of business operations, said in a statement. “Through the Steelheads Community Fund, we will celebrate the legacy of the Steelheads, while continuing our long-standing effort to advance access to baseball and softball and well-being for underserved communities in our region.”
