Welcome to Menlo-Atherton Little League Spring 2020 Registration!


Menlo-Atherton Little League registration is open to boys and girls of the appropriate playing age, whose families reside within, or attend a school that lies within the boundaries of the M-ALL, which can be found here. Players not residing in M-ALL boundaries will be placed on a waitlist pending confirmation of school attendance or prior registration in M-ALL.

Returning Players: when prompted, please use your email and password from previous seasons - it will save time and avoid duplicate entries in our database!

New to M-ALL Players: The Registration process for all new participants will begin with registration of Parents/Guardians. You will be asked for an email address, and then will be directed to the Registration portal for entry of a password. This email and password combination will be your keys to the M-ALL web portal in the future, so please select carefully. Once the first Parent/Guardian is registered, you may also enter the email and contact information for a second Parent/Guardian who will then be given access to the portal. Registrants must provide an email address for at least one Parent/Guardian.

Payment via credit/bank card is handled by Easy Merchant, who is a partner of our website provider, League Athletics. This transaction partner also helps keep the league's processing fees to a minimum. 

The M-ALL Board is committed to encouraging all interested children to participate regardless of the family's ability to pay the registration fee. Therefore, we have established a Scholarship program so that all children will have an opportunity to play Little League. Families seeking a player scholarship should complete the registration and then send an email to the requesting a scholarship consideration.

Please add   to your safe senders list or contacts to ensure email delivery and registration confirmation.  

Please contact if you have any questions.
