Registration for all Divisions is still open.

The anticipated season start date is July 1st.

If the season ends up getting cancelled, all registrants will be offered full refunds.

Click the blue banner above to access the registration system.


Based on City of Calgary and Alberta Provincial regulations, RMLL anticipates that regular season activities will be delayed until sometime after June 1st this year, subject to information and advice provided by Alberta Health Services, Little League Canada, and Little League International.

The four leagues in District 8, which include Rocky Mountain, Cal South, Cal West and Fish Creek, are collectively assessing options to run a summer baseball season in July and August. Our intent is to run a season as soon as we are able to do so safely. We will continue to adjust our planning as needed based on input from relevant health authorities and officials, and are striving to be as flexible as possible for our RMLL family.

Any RMLL players who want to withdraw can do so and will receive full refunds. Those who have asked if they can apply 2020 registration fees toward 2021, or who indicated they would like to donate 2020 registration fees to RMLL will also be permitted to do so.

To withdraw and request a refund, please see the email that was sent to all registered players. It includes a link to complete your request.

Please check your email, this website, and RMLL's Twitter and Instagram pages for the most current updates and information on plans to run a "warm weather" baseball season this year.

Until then, parents should access Big Al’s online training and development programs and resources for Parents and Players. See your email for full details.

Rose Diamond at Stanley Park - Home of Rocky Mountain Little League


Due to the recent global pandemic and the most recent decision by LL Canada to suspend all LL activities until at least May 11, 2020, this years RMLL Umpire Clinic has been cancelled. 

It is regretful, but out of an abundance of caution that we take this step.  It is my sincere hope that life will return to normalcy sooner rather than later and young people can get out and enjoy the great sport of baseball. 

Take care,

Jeff Anderson
