Baseball Rules Background

Monarch Little League is a member of Little League International, Colorado District 2. As a result, we operate based on three levels of gameplay bylaws (rules) for baseball:

1. Little League International Rulebook (new changes can be found here)

  • Institutes a new rulebook by January 1 every year.
  • These rules are the defacto standard for play if there are no district or local league bylaws.
  • These rules override district & local bylaws for All-Star games at District, State, Regional, & National division levels.
  • Paperback versions are provided with each AAA, Majors, Intermediate, and Juniors division team equipment bag.
  • Mobile phone App version can be downloaded for free. 

2. Colorado District 2 Bylaws (Updated 4/02/24)

  • Institutes a new set of bylaws by April 1 every year. 
  • These bylaws outline in more detail to the rules outlined in the Little League International rulebook.  
  • These rules are in effect for District 2 Interlock play typically used by the Majors, Intermediate, and Juniors divisions.

3. Monarch Little League Local Bylaws

  • Institutes a new set of bylaws by April 1 every year.
  • These rules outline adjustments to the District Bylaws or different details from the Little League International rulebook specific to items that work better for Monarch Little League as determined by the MLL Board of Directors.
  • These rules are in effect for play at the T-ball, Minors A, Minors AA, and Minors AAA divisions. In seasons with enough local teams, this can also be implemented at the Majors, Intermediates, or Juniors divisions.  
  • These rules can be obsoleted by the MLL board of directors if they believe it's easier to work to the District 2 bylaws.
