World Baseball Classic: Potential Midseason Shift and Future Outlook

The World Baseball Classic (WBC) is poised for continued growth and potential changes, including a possible move to a midseason tournament format. Following record-breaking attendance and viewership in 2026, Major League Baseball (MLB) is considering shifting the tournament from its traditional spring training slot to a midseason date, potentially as early as 2029 or 2030.

Record-Breaking 2026 Tournament

The 2026 World Baseball Classic saw significant increases in fan engagement. A total of 1,619,839 fans attended the 47 games, a 24% increase over the previous high of 1,306,414 in 2023. The tournament’s evolution from its inception in 2006, which drew 740,451 fans for 39 games, is undeniable. The Americans’ semifinal victory over the Dominican Republic was the most-watched game of the tournament, reaching 7.37 million viewers on FS1 and Fox Deportes, surpassing the previous high of 5.2 million for the 2023 final.

The Push for a Midseason Tournament

MLB Commissioner Rob Manfred has openly discussed the possibility of a midseason tournament, viewing the WBC as an ideal opportunity to test the concept. “As the game continues to evolve, we have talked about midseason tournaments in general. And certainly if we decided to get serious about this, about a midseason tournament, this would be an ideal opportunity,” Manfred stated in an interview with The Associated Press.

Currently, MLB has commitments to Fox for the All-Star Game through 2028, which influences immediate scheduling options. However, the success of the WBC is driving the conversation towards a more prominent place on the baseball calendar.

Addressing Player Participation Concerns

A key factor in considering a midseason shift is to alleviate concerns about player participation. Currently, the WBC takes place during spring training, allowing teams to potentially restrict players due to pitch count limitations or outright denial of participation. Moving the tournament to midseason would likely result in greater player availability.

Manager Mark DeRosa, for example, had to promise the San Diego Padres that closer Mason Miller would only be used in a save situation during the 2026 tournament. A midseason format, Manfred believes, would likely eliminate such restrictions, stating, “Certainly if it was moved to the middle of the season, I don’t believe you would have any nos for competing in it.”

WBC and the Olympics

MLB and the players’ association are also in negotiations regarding participation in the 2028 Los Angeles Olympics. A six-nation baseball tournament, including the U.S., Dominican Republic, and Venezuela, is planned during an extended All-Star break. The timing of the Olympics will influence the decision on when the next WBC will be held – either in 2029 or 2030.

Manfred acknowledged the need to balance these international commitments, stating, “The timing is going to turn on what we do with respect to related sorts of international efforts. I remain optimistic about the Olympics and obviously if we play in the Olympics it’s a short time from July of ’28 ’till the spring of 29 and that’s something we’ll have to take into account.”

Growing Global Appeal

The WBC’s growing popularity extends beyond traditional baseball strongholds. Italy’s unexpected run to the semifinals in 2026 sparked increased interest in the sport within the soccer-focused nation. The tournament is seen as a “springboard for the rest of our international efforts,” according to Manfred, fostering long-term business relationships with sponsors and broadcasters.

Japan, the Dominican Republic, and Venezuela remain passionate supporters of the tournament, having each won a title. The United States, despite fielding All-Star rosters, has only secured one championship in 2017.
