where to watch cleveland guardians vs seattle mariners

You can watch the Cleveland Guardians vs Seattle Mariners game through a mix of national streaming services and team-specific options, depending on the exact date and your location.

Quick Scoop

For the 2026 Opening Series in Seattle (late March 2026), the Guardians–Mariners games are spread across Apple TV, Peacock, local regional sports networks, and team streaming platforms. Here’s how it breaks down in practical terms.

Main Ways to Watch

  • Apple TV (Friday Night Baseball)
    • One Guardians at Mariners game is available as a live stream on Apple TV, listed specifically as “Watch Guardians at Mariners game on Apple TV,” including a Friday Night Baseball game on March 27, 2026.
* You need an Apple TV+ subscription and the Apple TV app.
  • Peacock (Sunday matchup)
    • At least one Guardians at Mariners game is carried exclusively on Peacock, described as “Guardians at Mariners” with a 3‑hour MLB broadcast and also listed by the Mariners as a Peacock-only Sunday game (e.g., March 29).
* Requires a Peacock subscription and the Peacock app.
  • Team streaming services (in-market)
    • Mariners.TV : If you’re in the Mariners’ home territory (WA, OR, ID, MT, AK, HI, plus BC/Alberta), you can stream most Mariners games, including Guardians matchups, on Mariners.TV, subject to national exclusivity (Apple TV/Peacock games are blacked out there).
* **CLEGuardians.TV / Guardians streaming** : Guardians games are available in-market via CLEGuardians.TV through the MLB app or your cable/satellite provider with a 2026 streaming package.
  • Regional sports networks (cable/satellite)
    • For non-national games, Mariners–Guardians matchups appear on local channels:
      • Mariners side: listed under “Mariners TV” (SEAM) in schedule writeups.
  * Guardians side: CLEGuardians.TV carriage includes AT&T U-verse (channels 736/1736), Cox (80), DIRECTV (662), Spectrum (306/1306 or 447 national, with variations by city).

* If you’re in either team’s home TV territory with cable/satellite, tune to your regional sports channel that carries Mariners or Guardians games.
  • National sports platforms
    • ESPN lists a “Cleveland Guardians vs. Seattle Mariners 3/28/26” event on its watch platform, indicating at least one game is viewable through ESPN’s streaming ecosystem (cable login or ESPN app, depending on rights).

Step‑by‑Step: Find Your Exact Option

  1. Check the date and time of your game
    • The 2026 season opener between Seattle and Cleveland at T-Mobile Park is noted as Thursday, March 26, 2026, 10:10 p.m. ET.
 * Other games that weekend fall on March 27 (Apple TV), March 28 (ESPN-listed), and March 29 (Peacock Sunday game).
  1. See if it’s a national exclusive
    • If your game is on Apple TV (Friday Night Baseball) or Peacock (Sunday night), those platforms are the only way to watch live, even if you have local RSNs.
  1. If it’s not exclusive, use local TV or in-market streaming
    • In Mariners territory, use Mariners.TV or the regional TV channel indicated by the Mariners’ schedule.
 * In Guardians territory, use CLEGuardians.TV via the MLB app or your cable/satellite provider and tune to the listed channels (AT&T U‑verse, Cox, DIRECTV, Spectrum, etc.).
  1. Out-of-market fans
    • If you’re outside both teams’ home regions, national broadcasts (Apple TV, Peacock, ESPN) will be easiest.
 * For other games in the series not picked up nationally, you would typically use the league’s out-of-market streaming option (e.g., MLB’s own service), checking blackout rules for your location.

Mini Forum-Style Take

“Opening weekend is split across everything: Apple TV on Friday, ESPN or local on Saturday, Peacock on Sunday, and local RSN/MLB streaming filling in the gaps. Plan ahead or you end up scrambling at first pitch.”

Fans on public sites point out that 2026 continues the trend of marquee series being spread across multiple streamers, so many people juggle Apple TV, Peacock, and a local option just to follow all three or four games.

TL;DR:

  • Check if your specific Guardians–Mariners game is tagged for Apple TV (Friday) or Peacock (Sunday) ; if so, you must use that app.
  • Otherwise, use Mariners.TV (if you’re in the Seattle territory), CLEGuardians.TV / RSN (if you’re in Cleveland territory), or a national platform like ESPN if scheduled there.
