SOFTBALL LEAGUE AGE
MBSA starts its new league year each Fall season, and the Spring season ends it. The Fall season is considered a developmental season to prepare for the Spring season. The age cut-off date for softball is August 31st. The player’s age on that date determines her “League Age” for the entire league year. This means that the player’s age on August 31, 2024 will be her league age for both the Fall 2024 and Spring 2025 seasons.
