ESPN’s exclusive coverage of the 2025 Major League Baseball Wild Card Series set multiple viewership milestones, fueled by strong performances from marquee matchups and significant gains among younger audiences, Nielsen’s Big Data + Panel reports show.
Across 11 games, ESPN networks averaged 4,625,000 viewers, marking the most-watched Wild Card Series under the current format and a 64 percent increase from last year. The surge reflects both the heightened interest in postseason baseball and ESPN’s expanding reach among key demographics.
Game 3 of the Boston Red Sox vs. New York Yankees series emerged as the standout, averaging 7,439,000 viewers. The matchup became the most-watched game of a Wild Card Series under the current structure and represented the largest audience for an ESPN MLB broadcast since 2021, when the Red Sox and Yankees faced off in a one-game Wild Card showdown under the previous format. Viewership peaked at 8,375,000 during the 8 p.m. ET quarter hour on Thursday, October 2.
Indeed, the Wild Card Series produced notable gains in youth viewership. Among viewers under 35, ratings jumped 89 percent compared with last year. Kids 17 and under tuned in at even higher rates, producing a 108 percent increase over the previous season. These gains highlight ESPN’s success in attracting new, younger audiences during critical postseason moments, a trend that networks have been closely monitoring amid evolving viewing habits.
The 2025 Wild Card Series featured compelling matchups that resonated with audiences across the country. The Red Sox-Yankees rivalry, often described as one of Major League Baseball’s most intense, proved a major draw. Game 3, which drew the largest ESPN MLB audience since 2021, showcased the league’s capacity to captivate both casual viewers and die-hard fans.
The wild card round of the MLB postseason marks the end of the ESPN broadcast agreements for television with the network opt-out earlier this year with MLB. ESPN Radio will still continue to provide live play-by-play coverage of the divisional, championship, and World Series rounds.
