18U Rules - Brought to you by TRIA






The following basic rules and regulations will govern play in the Metro Baseball League for 2013.  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 age of 19 before May 1, 2013.  It is permissible for a player to play up from their designated age division, but they may not play down.  For example, a 15 year old may play in the 18 year old division, but a 18 year old may NOT play in the 15 year old division.

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.
