Team Ownership Histories

The SABR Team Ownership Histories Project is a joint effort of SABR’s Business of Baseball Committee and the BioProject. The intention is to keep its essays up-to-date and to provide as much detail as possible about the organization and composition of ownership groups, franchise sales, relocations, stadiums, and other issues that provide the financial context for team success on the field.

The project has been expanded to include teams from the Negro Leagues, Federal League, AAGPBL, Players League, American Association, Union Association and defunct, 19th Century National League teams, an expansion pioneered by Charlie Bevis. Find those stories by clicking on the Defunct Franchises tab here.

This project is a continuing effort and volunteers for the uncompleted essays are encouraged to check the links at the bottom of the page and then contact Andy McCue at Thanks to Len Levin for his work in copy editing all of these essays.
