Seattle Mariners to celebrate 50 seasons in 2026 with yearlong events, fan tributes
Mariners to leave Root Sports; MLB taking over broadcasts in 2026
The Seattle Mariners have announced that starting with the 2026 season, their games will no longer be broadcast on Root Sports, the regional sports network the team is shuttering. Major League Baseball will take over broadcast and streaming production, though in-market fans will still be able to access games via their cable provider.
The Seattle Mariners will celebrate their 50th season in 2026 with a yearlong lineup of events, giveaways, and tributes honoring fans, players, and the community.
The celebration will be highlighted by 50 Seasons Celebration Weekend, scheduled for August 7–9 at T-Mobile Park, the team announced Wednesday. The weekend will include special events and the unveiling of the Top 50 Greatest Mariners Players, selected by fans and team legends.
"Celebrating 50 seasons of Mariners baseball is a tribute to the generations of fans, the community, and the Mariners players who have defined this franchise," said Kevin Martinez, Mariners president of business operations. "Their passion, dedication, and belief have carried this franchise for the past half-century, and their passion fuels our excitement for not only our 50 Seasons celebration, but also the next 50 years of Mariners baseball."
