3c395762511accd6ce791687cb9a531c_f9.jpgWELCOME!  The Murillo Minor Athletic Association (MMAA) is a rural association that operates a spring youth softball league on the volunteer power. The MMAA is based in Murillo, which is in the Municipality of Oliver-Paipoonge; west of the City of Thunder Bay, Ontario. 

The MMAA welcomes those who want to be involved in our recreational league, either as a player or as a coach, umpire, volunteer etc. The only thing you need is the desire to have fun and to ensure that our area youth have the opportunity to play recreational sports in a safe and supportive manner. The goal of our league is not to necessarily encourage winning, but to encourage good sportsmanship and the three F's; Fun, Friendship & Fitness.

Please take a few moments to browse our site and see what we are all about.

Due to the popularity of the MMAA softball league, we have added the older-aged Bantam division in 2022. Registration is based on birth year, but generally, those aged 4 to 18 years can play. We encourage you to provide your contact email so you can receive registration notices in a timely manner.

The Registration Fee is $75 per player, to a maximum of $225 per family (3 or more siblings).

A Late Fee of $15 per player applies effective Sunday March 5th, to a maximum of $45 per family (3 or more siblings).

Due to the League’s popularity, registration is on a first come, first paid basis. We accept only cash or cheque (payable to the MMAA). If you can’t attend one of these registration dates, contact Joe or Karen as soon as possible to make alternate arrangements. It has happened before that a Division reaches player capacity before the last registration date (especially T-Ball & 3-Pitch), so don’t delay.

THANK YOU to all the MMAA volunteers who devote their time and ensure our softball league’s continued success! New volunteers are always welcome to help with the following:

Team Coaches, Assistant Coaches, Scorekeepers
Player Registration
Uniform Distribution
Field Clean-Up Day & Field Maintenance
Equipment Supply & Maintenance
Team Photos
Umpire Clinic
Tournament & BBQ Day Preparation

Coaches/Assistant Coaches are always needed. Coaching is not difficult, and the only prerequisite is a desire to help the players and have fun. If you have some softball/baseball knowledge – even better!  Don’t be shy – we will show the ropes if you are new to coaching. If you are going to be at the games anyway, maybe you can help.


Thank you to the Municipality of Oliver-Paipoonge for the ongoing support with facility maintenance. 


To keep player registration fees low, we seek team sponsors and donations from the local community businesses. Team sponsors will have their business name / logo printed on team shirts and hats. A team sponsorship is $350. The 2023 SPONSORSHIP FORM is located under the Forms/Rules/Handouts tab. Please contact Joe or Karen for more information at mmaa1@tbaytel.net.
