Ashwaubenon Youth Baseball offers league's for players between Pre-Kindergarten to 12th grade. Because we partner with the Ashwaubenon Park & Recreation Department we can only accept registrations for players that are residents of Ashwaubenon or school-choice to a school in the Ashwaubenon School District.

League's are run in the spring/summer each year. We do not organize league's in the fall.

Family participation and involvement is essential to providing a positive program so we strongly encourage parent participation.

League Registration

T-Ball, Single A, Double A, Triple A, and Babe Ruth

League registration typically opens on or around January 1 each year. Registration will be open through January and February. Registration closes on the last day of February. Starting March 1, late registrations are accepted but a $50 late fee is applied. The final day we accept any registrations is typically the day before evaluations, but this is subject to change. Specific dates and deadlines will be posted on the AYB home page each season when they become available and reminder emails will be sent out when registration opens and nears closing.

How To Register: Registration needs to be completed online on this site. Registration links will be available on our home page at when registration is open.

JV Legion / Legion

Registration for JV Legion and Legion usually occurs in the early part of summer after earlier leagure registrations. Registration will be completed on this site. Information about how to register will be sent to parents when registration becomes available.



T-Ball does not have evaluations. Because scores are not kept and teams are randomly created, an evaluation is not necessary.

Single A, Double A, and Triple A

Evaluations for these leagues are organized because coaches will draft players to form teams. Evaluations are used to help coaches draft equal league teams based on players abilities. They are not used to determine eligibility for league play. All players who register for our leagues will be assigned a team. Dates and times may differ for different leagues depending on coach and player availability. Typically we try to organize these during early March so we have time to organize teams and order uniforms.

Babe Ruth / JV Legion / Legion

Babe Ruth, JV Legion and/or Legion evaluations/tryouts will only be held if it is deemed necessary after registration is completed. If a Babe Ruth evaluation/tryout is deemed necessary, it cannot be held until the freshman high school season is complete. A date will be communicated when it is finalized if needed.

2022 Evaluation Information

Ashwaubenon Youth Baseball will provide jerseys and hats for each league and tournament team player. Parents will need to provide white pants for each player. Rubber or plastic molded baseball cleats are recommended and would also be the responsibility of parents.


Baseballs and catcher's equipment will be provided for each team by Ashwaubenon Youth Baseball. Most players tend to bring their own bats so AYB does not provide bats for each team. However, if you do not have a bat, someone on each team is generally willing to share. If you are planning on purchasing a bat for your child, please see the baseball bat notice below. For hygienic and safety reasons, AYB prefers to have each player provide their own properly fit batting helmet. In case of hardship, we do have a couple helmets we could loan out for a season.

Bat Standards

T-Ball, Single A, and Double A Bat Standards

Ashwaubenon Youth Baseball allows two different kinds of bats in our youth leagues. Player's bats must have a USSSA stamp or a USABat stamp.

Volunteer Requirements

Concessions are an important part of the game day experience for fans and players, and also a key revenue generator for AYB. Running the concessions for a summer of leagues and tournaments takes a significant amount of help. As such, in order to provide a fair and quality experience, we ask that parents share in the responsibility.

Concession Deposit

We require each family to fulfill its concession stand obligation of working one shift per league player, and one additional shift per tournament team player (each shift is about two hours long). You will receive an invitation to pick shift(s) via SignUpGenius in April or May.

T-Ball, Single A, Double A, and Triple A:

If you do not sign up for a shift or fail to cover a shift, you will be charged an additional $149 per player the following season for your player to play.

Babe Ruth:

In lieu of the above, a deposit check of $149 is required per player due to the higher dropout rate. This check will be shredded as soon as your family fulfills its concession stand obligation. If you do not sign up for a shift or fail to cover a shift, your check will be cashed. Directions on how to submit this deposit check will be provided during the registration process.

Instructions For Submitting Your Deposit Check

Please do the following:

  • Make the check to: AYB, Inc.
  • Make the amount: $149
  • Include the word "Deposit" and your child's name in the memo area of the check.
  • Please mail or bring the check to:
    • AYB Inc.

Code of Conduct

In order to maintain a fun and positive environment for all, coaches, players and parents will read and agree to follow a code of conduct policy during the registration process. Coaches will agree to be role models and promote teamwork in a safe and positive environment designed to encourage and improve skills of each player. Coaches, players and parents will agree to demonstrate self control and embrace the values of good sportsmanship.

The same code of conduct is also posted at Ashwaubomay Park and available online. Any spectator at the baseball park will need to follow this code of conduct. Even though only parents and players will need to sign the code of conduct, we will enforce these policies with anyone in attendance at the park.
