Every Sunday home game, the Seattle Mariners take the field in Seattle Steelheads uniforms, honoring the city’s 1946 Negro League team and its place in Black baseball history. For many fans, the uniforms are a visible and powerful reminder of a legacy that helped shape the game long before integration.
But for the Mariners, the tribute goes far beyond what happens on the field.
Through the Steelheads Initiative, the organization has committed to a broader effort to connect that history to present-day impact. Central to that effort is the Steelheads Community Fund, backed by a $500,000 investment to support Black-led baseball and softball programs, along with community initiatives across the region. Additional funding comes from Steelheads merchandise sales and Sunday 50/50 raffles, creating ongoing opportunities for fans to participate in the effort.
Christian Halliburton, Seattle Mariners Deputy General Counsel and Senior Director of Government and External Affairs, said the idea to wear the Steelheads uniforms began with a desire to properly recognize the legacy of Negro Leagues Baseball and its influence on the sport.
“We know that the Negro Leagues were synonymous with baseball excellence, and were at the core of a vibrant industry that fundamentally influenced the game as we know it today,” said Halliburton. “So, we felt it was our duty to pay homage to that contribution in a way that connects the past with the present while looking towards an even brighter future.”
That commitment to honoring the past while investing in the future guided how the Mariners approached the initiative from the beginning. Rather than developing the program internally, the organization worked to engage community voices throughout the process.
“Instead of designing the program behind closed doors, we convened a series of meetings and ongoing conversations with community leaders and stakeholders so that we could listen to a variety of perspectives and learn about what it would take to build something that would feel real and resonate as authentic,” said Halliburton.
That approach also required reflection within the organization itself, including how the Mariners wanted to show up in their relationships with the community and how to align the initiative with broader values.
“It was also important that we engaged in honest reflection on our organizational identity, how we wanted to show up in our external relationships, and how we could align shared interests to guarantee that the Initiative was rooted in a genuine commitment to the intended outcomes,” said Halliburton.
The result is a multi-layered initiative that blends recognition, investment and community engagement. The Steelheads Sundays experience at T-Mobile Park, the uniforms and the community fund are all designed to work together as part of a long-term commitment rather than a symbolic gesture.
Halliburton said the investment in Black-led baseball and softball organizations reflects the Mariners’ belief in the role the sport can play in expanding opportunity and building community.
“The Steelheads and the Negro Leagues were the embodiment of these beliefs, and given the alignment with the Mariners core values, we were proud to be able to invest in a future that promotes access to baseball and shares our love for the game,” said Halliburton.
For many in the community, that investment represents more than funding. It helps create access points for young athletes who may not otherwise have opportunities to participate in organized sports, while also reinforcing the cultural significance of baseball in Black communities.
The initiative also extends beyond the field through partnerships that bring history into everyday spaces. Steelheads Alley, a Seattle brewery, taproom and event space, was developed in partnership with Métier Brewing Company to celebrate the legacy of the 1946 team while creating a gathering place rooted in that history.
The space features craft beer from Métier Brewing, one of the few Black-owned brick-and-mortar breweries in the country, along with visual displays that highlight the history of Black baseball and the Negro Leagues.
“Fans visiting Steelheads Alley are treated to exceptional brewed beverages and complementary food offerings, and they can enjoy those food and beverage offerings in a space that showcases the visual history that inspired it,” said Halliburton.
For Métier Brewing founder Rodney Hines, the space represents a powerful intersection of history, culture and community.
“Steelheads is busy, it’s vibrant, and what truly makes it different is when you pause and look up, you are met with powerful images of Black and brown softball and baseball players from the ’30s, ’40s, and beyond,” said Hines. “Stories deserving to be seen, remembered, and honored.”
“Humbly in partnership with the Seattle Mariners, the Black Heritage Society, and others, we are doing more than just telling history,” continued Hines. “We are making sure it is known, celebrated, and carried forward.”
For the Mariners, the Steelheads Initiative also serves as an opportunity to engage in broader conversations about the history of the Negro Leagues and the conditions that led to their creation.
The Negro Leagues were established during an era when Black players were excluded from Major League Baseball, yet they built a thriving and influential baseball culture that shaped the game in lasting ways. By honoring that history, the Mariners hope to highlight both the contributions of those players and the barriers they faced.
“It serves as a reminder of the contribution that Black and Latino players were making to the game even before Jackie Robinson broke the color barrier,” said Halliburton. “It gives us an opportunity to use that history to inspire the pursuit of a future of inclusion that those tremendous athletes dreamed of.”
The organization has also seen growing interest from fans who are learning about the Steelheads and the Negro Leagues for the first time through the initiative.
“One of the most exciting results of the Mariners launch of the Steelheads Initiative has been the number of baseball fans, young and old, who are discovering the Steelheads story and the legacy of the Negro Leagues for the first time,” said Halliburton.
By connecting history with present-day investment, the Steelheads Initiative reflects a broader effort to ensure that the legacy of Black baseball continues to shape the future of the game and the communities it touches.
