Major League Baseball's postseason television viewership continues climbing, with division series games averaging 4.17 million viewers, up 17 percent from last year and marking the best figure since 2011.

The viewership momentum extends across multiple rounds of the playoffs. Regular season and wild-card round increases have carried into the championship series, signaling sustained fan engagement with baseball.

Game 5 of the Tigers-Mariners series on October 10 became the most-watched American League Division Series game in 14 years. The 15-inning thriller averaged 8.72 million viewers on Fox.

The Yankees-Blue Jays matchup, won by Toronto, averaged 7.65 million viewers across the U.S. and Canada combined.

Through the first two playoff rounds, games are averaging 4.33 million viewers per game, up 30% from last year. This represents the highest level since 2010.

Canadian viewership for the Blue Jays-Yankees series averaged 3.65 million per game, up 10% from the last time the Blue Jays appeared in the ALDS nine years ago.

Game 1 of the American League Championship Series between the Mariners and Blue Jays averaged 5.31 million viewers on Fox in the U.S., up 32% from last year's comparable game on TNT Sports.

When including Canadian viewership of 4.7 million, Game 1 of the ALCS surpassed 10 million in total average viewership across both countries.

MLB Commissioner Rob Manfred attributed the viewership success to continued momentum in the sport. The league has also seen record attendance figures during the 2024 season.

"It's a continuation of the momentum that we've seen in the game," Manfred said.
