What Channel Is ‘Sunday Night Baseball’ on Tonight? Where To Watch The Mariners-Guardians Game

The 2026 MLB season continues tonight as the Seattle Mariners host the Cleveland Guardians on Sunday Night Baseball!

Thanks to MLB.TV, ESPN has no shortage of baseball coverage for the 2026 season. But the worldwide leader in sports no longer hosts Sunday Night Baseball. The franchise has moved to NBC and Peacock, starting with tonight’s battle between division winners from T-Mobile Park in Seattle.

This will be the final installment of a season-opening four-game series between the two teams, with the Guardians winning the first game 6-4. Chase DeLauter went three for five with two home runs, while Cal Raleigh and Julio Rodriguez went a combined 0-7 with six strikeouts. But that’s just one game of 162!
