With ROOT Sports no longer operating, the Seattle Mariners new home is Mariners.TV, with the MLB taking over local broadcast responsibilities. Tonight, you can watch the Seattle Mariners Opening Day game against the Cleveland Guardians live at 7:10 p.

SEATTLE — The 2026 season marks a new chapter for baseball fans. During last season’s playoffs, we learned that ROOT Sports would be going away for good. ROOT was the network that aired Mariners games.

A new era of watching Mariners baseball is here, and Mariners.TV has you covered all season long. • MLB makes in-market streaming subscriptions for 22 clubs available to fans And there's a bevy of options to stream regular-season games in the Seattle Mariners home territory with no blackouts (subject to national exclusivities).

The first game to be on KING 5 will be the Mariners matchup at home against the Houston Astros on Friday, April 10.

Seattle Mariners games this season will continue to have a home on local cable, with specific channels now set for their broadcasts.

The Mariners on Wednesday unveiled how traditional cable and satellite or internet television subscribers can access their games in 2026, specifically via what channels they’ll be on, beginning with Opening Day.
