The Names and Affiliations sub-screen (Game Menu >> Advanced section >> Setup and Options >> League Setup tab >> Names and Affiliations tab) screen allows you to change the names and abbreviations of any entity or award in a league at any time. You can also change the affiliations of any minor league teams in affiliated leagues. These settings are identical to the ones described during the game creation process.

Note: If you change the names of leagues, divisions, and teams after a game is already underway, these changes will not be tracked in historical reports. If you rename World Baseball League to My Baseball League, from that point forward all history reports will show 'My Baseball League' for all years, even those that pre-dated the change. However, if you archived reports from those years using the Almanac, the Almanac would retain accurate names.
