If you’re hunting for the seattle mariners espn schedule, you might be in for a bit of a shock. Baseball’s TV landscape just underwent a massive earthquake. The days of reflexively flipping to ESPN for every big Sunday night game are basically over.
It’s weird. For years, ESPN was the de facto home of primetime baseball. But in a move that caught a lot of fans off guard, ESPN restructured its deal with Major League Baseball. For the 2026 season, the "Worldwide Leader" has significantly scaled back its national broadcast slate to about 30 exclusive games.
Wait. Where does that leave the M's?
The reality is that the 2026 schedule for Seattle is scattered across a new map of streaming giants and old-school networks. If you want to see Julio Rodriguez under the bright lights, you're going to need more than just a cable sub.
The Big Switch: Why the Mariners ESPN Schedule Looks Different
ESPN opted out of its previous massive deal to focus on "tentpole" events. What does that mean for you? It means ESPN is saving its airtime for high-leverage days like Jackie Robinson Day (April 15), Memorial Day, and the Little League Classic.
Because of this, the seattle mariners espn schedule isn't a weekly occurrence anymore. Instead, the Sunday Night Baseball mantle has been picked up by NBC and Peacock.

Honestly, it’s a lot to keep track of.
One of the biggest national games for Seattle this year isn't even on ESPN. It’s the Sunday night clash on March 29 against the Cleveland Guardians. That game is a Peacock exclusive. If you're sitting there at 4:00 PM PT waiting for the ESPN theme song to hit, you're going to be staring at a blank screen or a college softball replay.
Key National Dates You Can't Miss
Even though the ESPN presence is thinner, the Mariners are still a national draw. The 2026 season marks the franchise’s 50th year. That kind of milestone usually gets the broadcasters interested.
Here is how the national "big game" schedule is shaping up for the M's:
- March 26: Opening Day vs. Cleveland. While not an ESPN exclusive, this is the earliest traditional Opening Day in history. Expect heavy coverage across MLB Network and local roots.
- March 29: Sunday Night Baseball (The "New" Version). This is the game against the Guardians at T-Mobile Park. It’s on Peacock, not ESPN.
- May 17: Another primetime slot. The Mariners host the San Diego Padres. Again, look to the NBC/Peacock umbrella for this one.
- August 9: A massive road test against the Houston Astros. This is currently slated for a national primetime window on NBC/Peacock.
What about the actual seattle mariners espn schedule? ESPN is being very selective. They haven't claimed every Monday or Wednesday night game yet, as those are often "picked up" closer to the date based on how the standings look. However, the Mariners are a prime candidate for a late-season "flex" game if they are chasing the Rangers or Astros for the AL West crown in September.

How to Actually Watch the Mariners in 2026
It’s a mess. Truly.
You’ve got the local games on the Mariners' own regional network, which is now more critical than ever since MLB took over local rights for several teams, including Seattle. Then you have the national "silos."
- Peacock: They own Sunday Night Baseball now.
- Netflix: Yes, Netflix. They’ve entered the chat with Opening Day rights and the Home Run Derby.
- ESPN: Still the home for Jackie Robinson Day and select holiday doubleheaders.
- Apple TV+: Friday Night Baseball is still a thing.
If the Mariners are playing a high-profile series against the Yankees (like the one starting March 30) or the Braves (May 4-6), those are the windows where ESPN usually swoops in.
The MLB TV Factor
There is one bit of good news. As part of the new broadcast reshuffle, ESPN now has a deeper integration with MLB.TV. For fans living outside of the Pacific Northwest, this makes it slightly easier to catch games that aren't blacked out.
But if you live in Seattle? You're still tethered to the local broadcast for 90% of the season.

The "national" games are actually the ones that cause the most headaches for local fans because they often trigger those annoying blackouts on your standard streaming packages. You think you're ready for the game, you've got your snacks, and then—boom—"This content is not available in your area."
Actionable Strategy for Mariners Fans
Don't get caught 10 minutes before first pitch trying to find a login.
First, check the official MLB app specifically for the "National Broadcast" tag on the seattle mariners espn schedule. If you see a game listed for Sunday night, 9 times out of 10 in 2026, it’s going to be on Peacock.
Second, if the M's are playing on a Monday or a holiday (like Memorial Day, May 25), that is your primary ESPN window. They love the tradition of those holiday matchups.
Lastly, keep an eye on the "flex" windows. Starting in August, ESPN and NBC have the right to change which games they air with about two weeks' notice. If Seattle is in first place, they will be on national TV a lot more than the early-season schedule suggests.
Sign up for a Peacock trial or subscription before the March 29 home opener against Cleveland. That is the first major "test case" for the new TV deal, and you don't want to miss the 50th-anniversary celebrations just because the channel changed.
