Significant changes could be on the horizon for MLB. Should the league expand to 32 teams, the divisions could be restructured based on location, MLB Commissioner Rob Manfred suggested during ESPN’s broadcast of the “Little League Classic” between the Mets and Seattle Mariners.

The idea unquestionably would create one of the biggest shake-ups in baseball and likely end the long-standing format that MLB has operated under for more than 100 years.

That’s news when the commissioner says it publicly, but impending realignment has not been a closely guarded secret. Expanding to 32 clubs would necessitate some reshuffling, the most likely of which would be moving to eight divisions of four teams apiece.
