Team Age Composition & Playing Up

  • AAA League
  • Single A League

Team Age Composition

Teams must have a minimum of 33% of their rostered players in their listed age divisions. For example, to be classified as an 11U team with a roster of 10 players, a team must have 4 or more players that have a baseball age of 11.

  • The baseball age for all players will be the age of the player on April 30th of the playing year.

  • Players are allowed to play up two age groups based on their date of birth (this does not apply to grade-level exceptions). If playing up two age groups a separate waiver will be required.

Playing Up a Division (Full Team)

Teams wishing to play up an entire age division must meet strict criteria for approval:

  • Undefeated WBL Spring Season (Gold Division).

  • Season run differential of +100 or greater.

  • Approved teams must register for the Gold Division.

Approval from the WBL Board is required before your team registers.
