⚾ Welcome to the Green Mountain Junior Baseball Association!

 

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

We offer programs for players from tee ball through age 14. As part of the Rocky Mountain Junior Baseball League (RMJBL), we welcome players of all skill levels, with opportunities ranging from introductory baseball to league and tournament play. Each season, we work to place players on teams where they can learn, develop, and enjoy the game. Team sizes and the number of teams depend on registration, but we strive to offer teams at every age level and welcome as many players as possible.

GMJBA is made possible by the dedication of our volunteers, including board members, coaches, and team parents. We thank them for the time and effort they contribute each season, and we’re grateful for the continued support of the Green Mountain community.

2027 GMJBA Age 14 Registration - Spring 2027

We’re excited to offer 14U baseball for the Spring 2027 season! Players will have the chance to build their skills, compete, and enjoy the game with their teammates. The 14U season starts and ends earlier than the 8U–13U season. We’ll share the schedule with families as details are finalized.

Registration fee: $395 per player

Registration includes a team jersey, hat, individual player photo, and team photo. Fees also help cover field use, umpires, equipment, and other costs of running the season.

Payment and refunds: A $75 portion of the registration fee is nonrefundable. Payment arrangements are available through TeamSideline, with the full balance due by March 31, 2027. Players with unpaid fees when games begin will not be eligible to participate in games until their fees are current. Once games have started, no refunds will be issued.

A limited number of scholarships or reduced fees are available for the 2027 season. Please contact the GMJBA President or Treasurer to request assistance.

Age eligibility: Players must be 14 or younger as of April 30, 2027, to register for 14U.

Teams are formed based on completed registrations. If we do not have enough players to form a 14U team, GMJBA will attempt to place affected players with another league. If placement is not possible, GMJBA will issue a refund.

We can’t wait to see our 14U players on the field!

2027 GMJBA Pee Wee Registration - Spring 2027

Team placement is based on your child’s age as of April 30, 2027, 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, 2027, 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.
