For the 2026 season, Seattle Mariners games are shifting away from ROOT Sports and will be available primarily via MLB-run streaming (MLB.TV / MLB app), the ESPN app, and select cable providers, with radio coverage on Seattle Sports 710 AM continuing in the Northwest.

Main ways to watch

  • MLB.TV / MLB app
    • MLB is taking over production and distribution of Mariners telecasts starting in 2026, with games offered directly through MLB platforms for both in‑market and out‑of‑market fans, ending the old ROOT Sports setup.
* Expect a subscription model similar to other MLB in‑market streaming packages, which have recently been around a monthly or season fee, though exact 2026 Mariners pricing has not been finalized yet.
  • ESPN app integration
    • Beginning in 2026, MLB.TV is being integrated into the ESPN app, so Mariners games will be accessible there for subscribers as part of MLB’s broader streaming rights deal with ESPN.
* Certain national “game of the day” style broadcasts may also appear via ESPN’s own baseball programming for viewers outside Seattle.
  • Cable and TV providers
    • Even with the ROOT Sports network shutting down, MLB and the Mariners intend to keep a traditional cable channel option, where local providers carry an MLB‑produced Mariners feed on a designated channel.
* Exact channel numbers and participating providers will vary by region and should be confirmed with each cable or satellite company closer to Opening Day.

Radio and audio options

  • Seattle Sports 710 AM
    • The flagship radio station for Mariners games in the Pacific Northwest remains Seattle Sports 710 AM, with coverage throughout Washington, Oregon, Idaho, Alaska, and British Columbia.
* Fans in the Mariners’ radio territory can also stream games via the Seattle Sports 710 app or SeattleSports.com without blackout restrictions.

Out-of-market vs local fans

  • Out‑of‑market fans
    • Fans outside the official Mariners home TV territory can watch games live or on demand on MLB.TV, as with other MLB teams, subject to standard blackout rules for national broadcasts.
* These viewers can use a wide range of devices (smart TVs, mobile, streaming sticks) supported by MLB.TV and ESPN’s integrated platform.
  • In‑market (Seattle / Northwest) fans
    • Starting in 2026, in‑market viewers are expected to have direct MLB.TV access to Mariners games as part of MLB’s takeover of both local and national rights for the team, removing the old local blackout dependency on ROOT.
* Local fans will also have cable and possibly over‑the‑top streaming bundles carrying the MLB‑produced Mariners channel feed, though specific packages will depend on provider deals announced before the season.

Forum chatter and workarounds

  • Fan tips from forums
    • On Seattle‑area forums, some fans mention using live TV streaming services (like YouTube TV or similar) that carry the relevant baseball channels or playoff broadcasts when the Mariners appear on national networks.
* Others discuss temporary free trials or alternative sports streaming sites around playoff time, but these options can be unreliable and may raise legal or quality concerns, so official MLB, ESPN, or licensed cable services are the safer choices.
