NBC Will Stream All 15 MLB Games on Peacock for July 5 Star‑Spangled Sunday

The network is using a coordinated mix of two NBC-produced national games, local feeds and a four-game multiview to try to extend Sunday Night Baseball’s recent ratings gains and boost Peacock subscriptions.

Overview

Peacock will serve as the central hub on Sunday, July 5, carrying every game on the MLB schedule and offering a curated four-game tile that lets subscribers watch up to four games at once and switch audio.
NBC will directly produce two marquee national telecasts — Mets vs. Braves and Padres vs. Dodgers — while most other games will use local broadcast crews with NBC’s theme music and a unified upper-left score bug on 14 of the 15 feeds.
There will be no single home-base studio show for the day and three locally produced games will be simulcast in their home markets on Peacock, with NESN’s Red Sox-Angels feed keeping its own graphics package.
The event is the largest production so far under NBC’s three-year MLB rights deal and follows strong early-season viewing, including a June 21 Sunday Night Baseball telecast that drew about 3 million viewers.
NBC frames the slate as a patriotic 'Star‑Spangled Sunday' for America’s 250th weekend and is using the single-day aggregation to test whether a centralized streaming offer and hybrid production model can build sustained audience and subscription growth.
