Little League Rules
https://www.littleleague.org/playing-rules/rules-regulations-policies/
Each year, Little League provides its constituent leagues with current Little League rules, regulations, and policies that outline and define the operation of the program. It is important for all Little League volunteers and parents to be familiar with the most up-to-date version of Little League’s Official Regulations, Playing Rules, and Operating Policies. These rulebooks, published for all divisions of Little League Baseball®, Little League Softball®, and the Little League Challenger Division® provide the structure and support for local leagues and Districts to provide a meaningful Little League experience for all children in their community.
