How big are teams and how long is the regular season?

A maximum of 15 players can be used in any regular season team, in both the Little League and Teenage divisions. Clubs with more than one team in an age division must spread the talent of the player pool evenly across their teams (except in the Senior League-only format, where players are allocated by suitability).

Little League-Major, Intermediate League (SL70) and Junior League (SL80) regular seasons must have no less than 12 games. If a season is shorter, no games in that grade count towards a player's game count. If games are lost to bad weather, a heat policy or a similar unavoidable event, the State District Administrator can seek written approval from the National District Administrator to validate the competition, provided at least 10 games were played.
