Adult Softball League Information

Each team must have a representative attend a mandatory captains’ meeting to be held via Zoom prior to the start of the season. This is the only meeting where rules, schedules, and league policies are reviewed. Teams who choose not to send a representative to the meeting are expected to abide by all polices and rules reviewed at this meeting.

All teams, whether new or returning, must submit to the Northbrook Park District the following items together to be considered for league entry:

  1. Complete team registration online
  2. Complete individual registration online. Link/forms will be provided after team registration is received.
  3. An Adult Softball League Team Roster/Waiver Form completed and signed by all team members by the fourth published game if individual registration form is not completed online.

Team Admission and League Assignments

All leagues are on a first come, first serve basis. Any teams that were expelled from the league due to forfeitures, rules violations, or misconduct, the league director has the right to exclude that team for the upcoming season.

Please register your team in the league in which you desire to play. The Northbrook Park District reserves the right to place teams in different divisions to equalize competition. In the event too many teams are seeking to enter the same league, league may be split into separate divisions.
