Credit: Brad Penner-Imagn ImagesNBC is introducing flex scheduling to Sunday Night Baseball, marking what appears to be the first time the long-running package has changed its nationally televised matchups after the schedule was announced. ESPN held the rights to Sunday Night Baseball from 1990 to 2025. Still, Sunday Night Baseball has been a strong draw for NBC overall. Last week’s New York Yankees-Philadelphia Phillies matchup averaged 3.2 million viewers on NBC. So even though NBC has scheduled some late-season duds, its overall strategy for Sunday Night Baseball appears to be paying off.
