If you're looking forward to the season debut of Sunday Night Baseball -- and who isn't? -- make sure you know where to find this weekend's marquee matchup.
Sunday Night Baseball has aired on ESPN since 1990, but beginning in 2026, Sunday Night Baseball is now on NBC. More specifically, you can find every Sunday Night Baseball Game streaming on Peacock.
Most Sunday Night Baseball games will also be simulcast on NBCSN -- NBC Sports' cable network. That includes this weekend's first Sunday broadcast between the Cleveland Guardians and the Seattle Mariners. First pitch between these two reigning division champions is slated for 7:20 p.m. ET.
NBC will also air its fair share of Sunday Night Baseball games. The first SNB telecast on NBC will be the April 12 showdown between the Guardians and the Braves. The network will then carry most of the Sunday Night Baseball games from May 31 through the end of the regular season. But you can always find Sunday Night Baseball streaming on Peacock. You will need a Peacock subscription to follow the action on the service.
Pregame coverage begins with Sunday Night Leadoff, hosted by Ahmed Fareed. For select games, the pregame show will also feature some big-name studio analysts: Clayton Kershaw, Joey Votto and Anthony Rizzo.
Twenty-nine-time Emmy winner Bob Costas will be the host of Sunday Night Baseball. The game's play-by-play announcer is Jason Benetti, who will serve with a rotating cast of color analysts, each with their own connection to a team in that week's spotlight game. For this Sunday's matchup, the analysts will be Guardians color commentator Rick Manning and Mariners broadcaster Ryan Rowland-Smith.
This week's Sunday Night Baseball game is just the start of a new three-year partnership between NBC and MLB. Make sure you don't miss a single pitch with Peacock.
