Today’s Seattle Mariners games are mainly on regional Mariners.TV or a national MLB partner channel like FOX, FS1, ESPN, TBS, MLB Network, Peacock, or Apple TV+, depending on the specific game and date.

Quick Scoop: What channel is the Seattle Mariners game on?

Because MLB TV rights are fragmented, there isn’t one single permanent channel for every Mariners game. Instead, where you watch depends on:

  • Regional streaming: Most in-market games now air on Mariners.TV , the team’s new regional streaming service for 2026.
  • National TV: Select games are picked up by FOX, FS1, ESPN, TBS, MLB Network, Peacock, or Apple TV+.
  • Out-of-market streaming: You can usually watch via MLB.TV if you’re outside the Mariners’ local territory (subject to blackout rules).
  • Cable/streaming bundles: Services that carry those sports networks (like certain cable providers or live TV streamers) will show the game when that network has the rights.

Think of it like a rotating stage: most nights the game is “on the home channel” (Mariners.TV/MLB.TV), but some nights a national network steps in and takes over the broadcast.

How to find today’s exact channel

Because the channel changes from game to game, you’ll need to check a current listing rather than rely on a static answer. The fastest ways are:

  1. Check the official Mariners schedule “How to Tune In” page :
    • Go to the Mariners’ official site and open the Watch/How to Tune In section; it lists each game with its TV partner (Mariners.TV, FOX, ESPN, Peacock, etc.).
  1. Use a daily TV schedule site :
    • Sites that list “Seattle Mariners game today channel” will show today’s opponent, first pitch time, and exact channel (e.g., Mariners.TV, FOX, ESPN).
  1. Look at your provider’s guide or app :
    • If you have cable or a live TV streaming service, search “Mariners” in the guide around game time; it will surface the correct channel based on your package.
  1. If you’re local to the Pacific Northwest :
    • Expect most regular-season games to be on Mariners.TV (streaming) with occasional exclusives on Peacock or FOX and a handful on ESPN/FS1/TBS.

In practice: if the game is tonight and you’re in Washington, your best bet is to start with Mariners.TV, then confirm on the official schedule if a national network has picked it up.

Mini TL;DR

  • There is no single fixed channel for every game.
  • Most in-market games: Mariners.TV (regional streaming) and/or MLB.TV.
  • Some games: FOX, FS1, ESPN, TBS, MLB Network, Peacock, Apple TV+ instead.
  • To know today’s channel, check the official Mariners schedule or a current TV listings site for your area.
