MLB Expansion 2025: How 32 Teams Could Reshape Divisions and Rivalries

Explore how MLB's potential expansion to 32 teams could lead to radical divisional realignment, new rivalries, and changes to the playoff format.

The Future of MLB: Expansion and Realignment

Major League Baseball is on the brink of a significant transformation. With talks of expanding to 32 teams, the league is poised to undergo a radical realignment that could reshape divisions, rivalries, and the playoff structure. Commissioner Rob Manfred has hinted at the possibility of geographic realignment to reduce travel wear and tear on players, while also making the postseason more appealing for broadcasters.

Divisional Realignment: Four or Eight Teams?

One of the most debated topics is how divisions will be structured. Will MLB stick with the traditional four-team divisions, or will it move to eight-team divisions? The latter could create more balanced schedules and reduce travel, but it might also dilute some historic rivalries. For instance, the Yankees and Mets could end up in the same division, sparking a new chapter in their storied rivalry.

Playoff Format: More Teams, More Drama

Expansion will inevitably lead to changes in the playoff format. Currently, 12 teams make the postseason, but with 32 teams, that number could increase to 14 or even 16. This would create more opportunities for teams to compete for a World Series title, but it could also lead to concerns about the integrity of the regular season. The MLB Players Association has floated the idea of a 'ghost win' for higher-seeded teams, adding another layer of strategy to the postseason.

Rivalries: The Heart of Baseball

Rivalries are the lifeblood of baseball, and any realignment must consider their importance. The Yankees-Red Sox, Giants-Dodgers, and Cubs-Cardinals rivalries are sacrosanct, but new rivalries could emerge with geographic realignment. For example, the Astros and Rangers have developed a fierce rivalry in recent years, and a divisional realignment could intensify that competition.

The Road Ahead

As MLB moves closer to expansion, the league will need to balance tradition with innovation. The decisions made in the coming years will shape the future of baseball for decades to come. Whether it's through divisional realignment, changes to the playoff format, or the creation of new rivalries, one thing is certain: baseball is about to enter a new era.
