Spring 2018 Registration

March 27, 2018: AA, AAA and Majors Leagues are currently only accepting waitlisted registrations. 

March 10, 2018: Seniors League is currently only accepting waitlisted registrations. 

Welcome to 2018 Brookline Youth Baseball! We’re excited to have everyone back for a new season, and look forward to welcoming new players and families to BYB. Let’s get started:

Registration is simple and based on your child’s age. Please see Team and Placement for information about how players are placed in leagues. The registration deadline to guarantee a spot for the spring season is March 11, 2018. Also, for all players age 9 and older please see important information about tryouts at the end of this message.

If you are wondering whether your 8 year old should play A or AA, click here for more information.

RETURNING THIS SEASON: The Sean Roberts Baseball Challenger League offers its second spring program for children with disabilities age 7 and up. Click here for more information and follow the usual link to register.

IMPORTANT NOTE: Payment is required at the time of registration. Although you can exit the registration process without submitting payment, your registration will be deleted a short time later. At that point your registration will not be valid and your registration priority may not be preserved. Priority becomes important when a program is over-enrolled and a wait list is necessary.

To register your child, please read the following:

1. If you are new to BYB, you’ll need to set up an account within our system. Please see “Access or Create Your BYB Account” below for instructions. This will be the only time you’ll need to do this, and it will set us up with your parent and child information until you tell us something’s changed.

2. If your child has played in BYB previously click “Register Now” just to the right on this page. It’s Big. It’s Orange. If you can't access your account or if you have any other problems during the registration process please Please do NOT create additional accounts. Contacting us establishes your registration priority. We will correct the problem and you won't "lose your place in line" should a league become oversubscribed.

3. Remember, if you are stuck somewhere on the site and can't find a way to register, it’s always the Big Orange Button on the home page. (When in doubt, run home!)

5. If you have any questions about how the site functions, please see the FAQ’s. If you have trouble with the website, please . If you have any questions about individual BYB baseball programs or any other specific concerns, please contact the appropriate board member at our contact list.

Important information about tryouts for players age 9 and older:

  • All players must register before tryouts.
  • The tryout schedule is shown below. During registration you will be asked to select a specific tryout session.
  • Players should arrive 15 minutes before the scheduled time to allow time for check in and warm up.
  • Players should bring a glove and wear sneakers (no cleats).  Please DO NOT wear jerseys or hats from summer travel teams.
  • Per Little League and BYB rules all players who are league age 10, 11, or 12 and with to play in Majors, including returning Majors division players are required to attend at least one tryout.

Coaching Is . . . Ten Reasons YOU Should Become a Baseball Coach
New coaches are the lifeblood of the system that keeps BYB dynamic and active. Every small era in our development is owed in great part to the parent volunteers who choose to get involved, stay involved and grow their teams. To those who love to spend time with their kids and their kids’ friends, and who value the life lessons that baseball teaches, we proudly invite you to get involved.
  1. Coaching is about giving kids confidence by teaching them a game that literally changes lives.
  2. Coaching is hauling the gear bag around like a custodian, because you are one.
  3. Coaching is a chance to make all kinds of new friends (especially the young ones).
  4. Coaching is making every player know s/he’s the best one on the team.
  5. Coaching is two hours on a green grassy field where the office can’t reach you.
  6. Coaching is the high-fives you give and get from the sweetest faces.
  7. Coaching is assuring a dejected child that the sun will rise tomorrow.
  8. Coaching is a tribute to your own kids’ dreams.
  9. Coaching is a tribute to your community.
  10. Coaching is a tribute to the ones who coached you.
