⚾ Welcome to the Green Mountain Junior Baseball Association!

 

Green Mountain Junior Baseball Association (GMJBA) is a nonprofit, volunteer-driven organization that has proudly served the Lakewood/Green Mountain community for over 25 years. Our mission is to provide a fun, safe, and competitive baseball experience for local youth.

We offer baseball programs for players up to 14 years old, catering to all skill levels—from tee ball to teams competing in the Rocky Mountain Junior Baseball League and tournament-only teams. Our goal is to place players on teams that match their skill level, ensuring the best possible experience for every athlete. While team sizes and numbers may vary each season based on registration, we strive to field teams at every age level without limits on the number of teams.

The success of our league is made possible by dedicated volunteers, including our board of directors, coaches, and team parents, who all play a vital role in upholding our mission and values.

2026 GMJBA Age 14 Registration - Spring 2026

RAMS Day for the 2026 spring season will be held on Saturday, September 20, 2025 at Ray Ross Park from 9:00 am to Noon. A make-up day will be offered on Monday, September 22, 2025 at Lakewood Park from 5:00 pm to 7:00 pm.

Player’s age group is determined by the player’s age as of April 30, 2026. For example – if your player turns 14 on or before April 30, 2026, then your player should be registered for the 14U team.

An initial, non-refundable registration fee of $75 is required to register and be placed on a team for 2026. Your child will not be able to participate in RAMS Day unless this fee is paid — NO EXCEPTIONS. This fee will be applied toward the total due for the 2026 season.

NOTE: If your child participates in RAMS Day, but subsequently withdraws from GMJBA, the registration fee will not be refunded. The balance of the registration fee of $320 is due by February 15, 2026, unless prior arrangements have been made and approved by the President or Treasurer. You must pay the $75 minimum or the entire balance at the end of registration, or your child will not be registered with GMJBA. Players with unpaid fees at the beginning of the season will not be able to participate in games until those fees are paid. Once games have started for the 2026 season, no refunds will be issued. Reduced fees or a limited number of scholarships are available for the 2026 season. Requests must be made through the President or the Treasurer. Teams are built based on registrations. If there are not enough registrations to build a team at your child’s level by the start of the season, GMJBA will attempt to place your child with another league and will provide a refund.

RAMS Day for 8U–13U team registration for the 2026 spring season will be held on Saturday, September 20, 2025 at Ray Ross Park from 9:00 am to Noon. A make-up day will be offered on Monday, September 22, 2025 at Lakewood Park from 5:00 pm to 7:00 pm. Player’s age group is determined by their age as of April 30, 2026. For example, if your player turns 12 on or before April 30, 2026, they should be registered for the 12U team.

An initial, non-refundable $75 registration fee is required to register and be placed on a team for 2026. Your child may not participate in RAMS Day unless this fee is paid — no exceptions. This $75 will be credited toward the total balance for the season. If your child participates in RAMS Day but later withdraws from GMJBA, the $75 will not be refunded.

The remaining balance of $320 is due by February 15, 2026, unless prior arrangements are made with the President or Treasurer. You must pay at least the $75 minimum or the full balance at registration, or your child will not be considered registered with GMJBA. Players with unpaid fees at the start of the season will not be eligible to participate in games until fees are current. Once games have started, no refunds will be issued.

A limited number of scholarships or reduced fees are available for the 2026 season. Requests must be submitted to the President or Treasurer. Teams are formed based on completed registrations. If there are not enough players to build a team at a specific age level, GMJBA will attempt to place your child with another league and will provide a refund if placement is not possible.

2026 GMJBA Pee Wee Registration - Spring 2026

Team placement is based on your child’s age as of April 30, 2026, with the goal of making sure every player has the right mix of fun, learning, and challenge. For example, if your child turns 4 on or before April 30, 2026, they’ll start out in Tee Ball. Families also have the option to “play up” if a player is ready for the next level.

  • Age 4: Tee Ball – a great introduction to the game.

  • Age 5: Tee Ball (for brand new players) or Coach Pitch (for those with one year of Tee Ball and ready to move up).

  • Age 6: Coach Pitch – building confidence and skills.

  • Age 7: Coach Pitch or Modified Kid Pitch – placement depends on prior baseball experience.

Our goal is to place each child where they can learn, grow, and enjoy the game while preparing for the next level.
