CMBA wants to help with getting information out to our members for them to make the best educated decision they can. We want you to provide proper and safe equipment for your child as it can be instrumental in the development and successes your child can have. Below are provided guidelines for the different equipment your child may be using. Please use this information as a guideline to help assist you with asking the proper questions when looking to purchase any of these items. Other factors such as players size, skill level and overall comfort of the equipment should also play a factor in what you provide your child.

Additional Information:
The 17U Canada Cup Championship is a wood bat only championship.
The Baseball Alberta Community Leagues will follow the 'A' category bat regulations for each age group.
In all divisions, the bat must clearly show the manufacturer's original markings, including, if applicable, length-weight differential. If not, the bat will be considered illegal.
A player is to follow the bat rule based on the age division that they are playing in during the game. For example, a 13U aged player participating in a 15U game is subject to the 15U bat regulation. A 16U aged female athlete playing in a 15U game is subject to the 15U bat regulation.
