12 Year Old Rules - Brought to you by TRIA







The following basic rules and regulations will govern play in the Metro Baseball League for 2019.  The list of rules and regulations is NOT intended to cover all of the playing rules, but rather highlight those areas that are referenced most often by the coaches and participants.  In general, the MBL Board of Directors has adopted the National Federation High School League rules.  Except where modified below.


A.           Players in their respective age groups must not reach the next age before May 1, 2021.  It is permissible for a player to play up from their designated age division, but they may not play down.  For example, an 11 year old may play in the 12 year old division, but a 13 year old may NOT play in the 12 year old division.

B.           Rosters are due before the first game and must be done on-line. A player may only be rostered on one team.  There is a maximum of 18 players per team.  Roster changes may be made through June 12021.  Any player(s) added after June 12021, must be accompanied by the association's travel directors signature and approved by the MBL Board of Directors.


A.              The Metro Baseball League is a community based program.  Players are eligible to participate on teams from the community in which they live with their parent(s) or legal guardian, or their school attendance area.  In some cases a "natural baseball community" exists which may be a combination of nearby communities based on high school attendance area or other demographics.  However, this is NOT intended to allow all-star or recruited teams to be formed.  The MBL Board of Directors reserve the right to rule on any questionable situations.

B.  If a player attends a private school in another community, the option is for that player to play for that school’s summer program. e.g.- if a player lives in ‘Pipestone’ and attends school at ‘Holy Angels’ then the player would be eligible to play for either Pipestone’s Or Holy Angels Summer Program.

C.  Club Ball and double rostering is now the responsibility of each individual association.


A.              In order to encourage the development and expansion of baseball within the state and to provide for uniformity of competition for the purpose of obtaining these goals, the MBL shall be divided into three competitive levels as herein provided.  The policy of the MBL is that all associations must have a "AAA" team to have a "AA" team unless they petition the board for an exception.  It shall be the responsibility of each association to maintain the integrity of each level within their own association and to properly classify their teams.

“AAA” -The highest competitive level and every association shall have the right to enter teams in the AAA League level.

AA”- The intermediate level, primarily intended to provide a uniform competitive experience for communities that are not able to compete at the AAA League level or communities that already have teams at the AAA League level.

A”- The intermediate level essentially designed to be a developmental league to provide a competitive experience until they are ready to advance to a higher competitive level.
