You’ll generally watch Seattle Mariners games on Mariners.TV or a national sports channel , depending on the day and your location.

Main ways to watch (2026)

  • Local Seattle/PNW fans (in-market): Most regular-season games are on the Mariners’ new regional channel and streaming service, Mariners.TV.
  • National TV games: Some games move to Apple TV, FOX, FS1, NBC/Peacock, TBS, MLB Network , or other league partners on specific dates.
  • Out-of-market fans: If you don’t live in the Mariners’ home territory, you usually need MLB.TV or MLB Extra Innings to see most games.

Why there isn’t one single channel number

The exact channel number for Mariners.TV depends on your TV provider (Xfinity, DIRECTV, Fubo, Spectrum, Astound/Wave, TDS, etc.) and your city, and each provider puts Mariners.TV on a different channel slot. If your package carried Mariners games last year, teams and networks say it should still include Mariners.TV this season.

In practice, the fastest move is to:

  1. Open your cable/satellite guide and search for “Mariners” or “Mariners TV”, or
  2. Visit the Mariners’ official “How to Watch/How to Tune In” page and use their channel finder for your provider and ZIP code.

TL;DR:
Search your TV guide for “Mariners TV” or check the Mariners’ official schedule page for tonight’s listing; nationally televised games may instead appear on Apple TV, FOX, FS1, Peacock, TBS, or MLB Network.
