MLB playoff audience falls 13% after a five-game World Series
The postseason averaged 5.49 million viewers, down from 6.33 million in 2025. Milwaukee’s sweep of the Dodgers drew the largest LCS audience since 2015.
The 2026 Major League Baseball postseason averaged 5.49 million viewers across reported telecasts on Fox Sports, TNT Sports and NBCUniversal outlets, down 13% from 6.33 million a year earlier. Outside of 2025, it was the most-watched postseason since 2019, according to Sports Media Watch.
The postseason was down by single digits entering the World Series. The gap widened after Milwaukee and Tampa Bay played a five-game championship series that averaged 11.69 million on Fox. Last year’s seven-game series between the Los Angeles Dodgers and Toronto Blue Jays averaged 15.71 million. The latest Fox average was 26% below that figure.
Two other five-game World Series put the decline in context. The Dodgers and New York Yankees averaged 15.21 million in 2024, while the Texas Rangers and Arizona Diamondbacks averaged 9.11 million in 2023. Brewers-Rays came in 23% below the Dodgers-Yankees series and 28% above Rangers-Diamondbacks. Nielsen has changed its measurement since 2024, so those older figures are best read as reported historical comparisons.
The Brewers drew one of the largest audiences of the postseason before the World Series. Their four-game sweep of the Dodgers averaged 7.53 million, the best for either league’s Championship Series since the New York Mets swept the Chicago Cubs in 2015. Game 1 drew 10.72 million following NFL coverage, the biggest audience for an LCS game since 2010.
Sports Media Watch said the postseason average excludes two Wild Card Series, White Sox-Astros and Cubs-Padres, that aired on Peacock and NBCSN. The World Series average cited here covers Fox. Figures that combine Fox with Spanish-language coverage can therefore differ from the Fox-only numbers.
The two Milwaukee series show how far audiences could vary across rounds. Its sweep of Los Angeles set a decade high for an LCS even though the next round fell well short of the previous World Series. The game-by-game numbers, including combined Fox and Fox Deportes numbers where available, are in TSP’s World Series ratings tracker.
