Mariners Announce Closure of ROOT Sports
The Seattle Mariners have announced that they will cease operations of ROOT Sports Northwest at the conclusion of the 2025 Major League Baseball (MLB) season, transitioning all broadcasting and streaming responsibilities to MLB starting in 2026. This decision marks the end of ROOT Sports, which has been the primary broadcaster for Mariners games since its inception in 1988 as Northwest Cable Sports. The final broadcast on ROOT Sports will occur on September 29, 2025, during the team's last regular-season game against the Los Angeles Dodgers.
Background and Context
The Mariners acquired full ownership of ROOT Sports in 2023, having previously held a controlling stake since 2013. The decision to shut down ROOT Sports comes amid a broader decline in the viability of regional sports networks (RSNs), which have struggled to retain subscribers as more fans opt for streaming services over traditional cable packages. The Mariners' move reflects a growing trend among MLB teams, with several others, including the San Diego Padres and Colorado Rockies, having already shifted their broadcasting to MLB.
Key Figures Involved
Mariners CEO and Chairman John Stanton has been a pivotal figure in this transition, having led the franchise since 2016. Stanton informed ROOT Sports staff of the impending closure during a meeting at the network's headquarters in Bellevue, Washington. The announcement has resulted in the layoff of over 25 employees, effective November 3, 2025.
Why This Matters
The Mariners' shift to MLB broadcasting is significant as it highlights the changing landscape of sports media. With the decline of cable subscriptions—ROOT Sports' subscriber base dropped from 3.3 million in 2014 to just 1.2 million in 2024—the team aims to adapt to new viewing habits and streamline operations. MLB's involvement is expected to provide fans with enhanced features and benefits, although specific details regarding channel assignments and streaming options remain unclear.
Official Statements & Responses
In a statement, the Mariners expressed their commitment to finding new ways to engage fans, stating, “We continue to focus on finding new ways to bring our games in 2026 and beyond to our fans and we’ve determined joining with Major League Baseball is the best path.” They also acknowledged the dedication of ROOT Sports staff over the years, emphasizing the end of an era for the network.
Criticism & Opposition
While the transition aims to modernize the Mariners' broadcasting approach, it has raised concerns among fans about potential disruptions and the loss of familiar broadcasting talent. Critics point to the challenges faced by ROOT Sports in recent years, including the loss of rights to other local teams like the Portland Trail Blazers and Seattle Kraken, as indicative of the network's declining relevance.
Conflicting Reports & Gaps
There are uncertainties regarding the future of Mariners broadcasting talent, with some reports suggesting that current announcers may not remain with the new MLB-run broadcasts. Additionally, the financial implications of this transition on the Mariners' revenue and player payroll remain to be seen, as the team may face reduced television revenue compared to previous RSN agreements.
