MLB’s Star-Spangled Sunday to air all 15 games across NBC and Peacock platforms on July 5

MLB is turning one of its mid-summer Sundays into a national broadcast event. For July 5, the league is highlighting “Star-Spangled Sunday,” an NBC and Peacock initiative designed to run every Major League Baseball game on the day’s slate across the network’s platforms.

The plan, according to MLB’s official announcement, is to showcase all 15 games from that date using NBC, Peacock, and NBCSN, keeping viewers within the same overall media umbrella rather than scattering coverage across separate outlets. The theme is explicitly tied to America’s 250th birthday weekend, with the broadcast package positioned as a “one place” way to watch baseball during the holiday stretch.

MLB’s release frames the day as both a scheduling and presentation project. “Star-Spangled Sunday” is meant to be comprehensive, with the league emphasizing that the networks will handle coverage for the full slate. That matters for fans because MLB’s national footprint is often split across multiple days and channels, making it harder to find all games in one sitting without switching services or outlets.

The league also notes that most of the matchups are expected to be exclusive to the Peacock platform, with NBC and NBCSN filling in the remainder. That distinction is central to how the broadcast day is likely to feel for viewers. It effectively positions Peacock as the primary destination if you want to follow the entire set of games without gaps.

While the promotion is themed around the July 5 holiday weekend, it is still, at its core, a baseball scheduling story. MLB’s regular-season slate on that date becomes the centerpiece of a coordinated media push, and the “all 15 games” element underscores the league’s intent to treat the day as a complete viewing experience rather than a selection of headline matchups.

For teams and players, a league-wide broadcast day can raise the visibility of otherwise background parts of the schedule, especially for clubs that might not otherwise land on national television often. For broadcasters and advertisers, it compresses consumption into a single date with a shared identity, which can help concentrate attention and viewing flow.

As July 5 approaches, the key thing for viewers to watch is how the network breakdown will work in practice: which games land on NBC or NBCSN and which ones remain Peacock-only. Once the game-by-game assignments are fully published, fans can plan their viewing across the three platforms to cover the entire 15-game slate.
