The schedule of MLB games on NBC and Peacock, the new homes of primetime Sunday games, was released on Friday, and it includes a quartet of Mariners games in Seattle’s first season after reaching the American League Championship Series and winning the AL West for the first time in over two decades.

Here are the Mariners’ four Sunday Night Baseball games, which includes the debut Sunday night game in MLB’s return to NBC:

• March 29, 4 p.m. – Mariners vs. Cleveland Guardians (NBC and Peacock)
• May 17, 4 p.m. – Mariners vs. San Diego Padres (Peacock)
• July 5, 2 p.m. – Mariners vs. Toronto Blue Jays (Peacock)
• Aug. 16, 4 p.m. – Mariners at Houston Astros (NBC and Peacock)

The July 5 game against the Blue Jays, who beat the M’s in seven games in the 2025 ALCS, will be part of “Star Spangled Sunday,” with all 15 MLB games on the day after Independence Day airing on Peacock.

Only the World Series champion Los Angeles Dodgers, Boston Red Sox and San Diego Padres have more scheduled Sunday Night Baseball games in 2026 than Seattle. For the full Sunday Night Baseball slate, click here.

MLB prepared to produce and distribute TV for nine more teams

The Mariners have been featured more frequently in primetime in recent years. They ended a 20-year absence from Sunday Night Baseball on ESPN in August 2024, and played two more Sunday night games last season, including the final Sunday Night Baseball game on ESPN when they completed a huge sweep in Houston on Sept. 21 that was crucial in their run to the division title.

The M’s will open the 2026 regular season on Thursday, March 26 with a 7:10 p.m. matchup with Cleveland that opens a four-game series and seven-game homestand.
