2026 Seattle Mariners Cable TV Channels Announced

This article breaks down how the Seattle Mariners will broadcast their games in 2026. It details the return of local cable coverage, a new streaming option, radio plans, and what opening day might look like as the team rides a wave of recent on-field success.

Local TV and Streaming: Mariners’ 2026 Broadcasting Plan

The Mariners will still be on local cable in the Seattle–Tacoma area, even as the rest of the league keeps changing how it does things. Besides the usual TV setup, MLB’s broadcasting arm now offers a streaming option for fans who ditched cable, so you won’t have to miss live games just because you cut the cord.

This two-pronged approach tries to balance that old-school, in-market TV vibe with a fresher streaming path. For 2026, Seattle fans can expect things to stay pretty familiar on TV, but there’s a bit of a refresh online too.

Root Sports has finished its move away from traditional TV. Now, it’s a streaming service under the Mariners’ broadcast umbrella, called Mariners TV. The idea is to keep local fans connected and maybe rope in new viewers through digital channels.

TV distribution and channel lineup

In the Seattle/Tacoma region, Mariners games will show up on Xfinity channel 1261 and Spectrum channel 414. That should cover most local households, even as TV keeps shifting under our feet.

More distributors will get announced soon. There’s a channel finder coming to help fans figure out where to watch Mariners broadcasts, no matter their provider.

Keeping access steady and predictable for local fans is the main goal here. At the same time, the team wants to make it easy for folks who rely on streaming instead of cable.

Mariners TV streaming service

Mariners TV subscriptions will run you $99.99 for the season or $19.99 monthly. It’s not nothing, but it’s a budget-friendly way to stream if you’re not into cable.

The streaming service falls under MLB’s broadcasting arm, so you’ll get the same game-night programming as the classic telecast. Beyond Seattle, the Mariners’ digital reach stretches into Washington, Oregon, Idaho, Montana, British Columbia, and Alaska—sometimes through the Mariners Radio Network app ecosystem, depending on where you are.

Radio Coverage and Opening Day Schedule

Radio’s still a staple for longtime Mariners fans. The Mariners Radio Network flagship on Seattle Sports anchors the coverage.

The Seattle Sports app brings the broadcast to fans across the Pacific Northwest and even further if you’re on the go. It’s a nice complement to TV and streaming, with those familiar team voices bringing the action live.

For opening weekend, Seattle Sports will roll out a bunch of live programming as the team kicks off the season. You’ll get in-stadium energy, live radio play-by-play, and app updates from pregame to the final out. It’s a full-on experience, honestly.

Opening day details and broadcast timing

The Mariners open the 2026 season at 7:10 p.m. on Thursday at T-Mobile Park against the Cleveland Guardians. Pregame coverage on the Mariners Radio Network starts at 6 p.m., so listeners get a whole hour of analysis, lineup notes, and commentary before the first pitch.

Seattle Sports will run extensive live programming all day to capture the buzz and nerves of opening day. If you’re a fan, you’ll have plenty of ways to tune in.

Season context and expectations

Heading into the year, the Mariners just came off their first division title and an AL Championship Series appearance in 24 years. That kind of recent success has fans buzzing, eager for in-market broadcasts and more ways to tune in online.

People want to follow a club that’s finally shown it can compete at the highest level. The broadcast strategy—mixing reliable local TV, a strong streaming option, and lively radio coverage—tries to turn that on-field momentum into bigger viewership and deeper fan engagement.
