2021 Virtual Rules Clinic Video Sessions

We separated our yearly Little League Rules Clinic into 3 sessions over 3 different nights. Each session reviewed different rule sections from the Little League Baseball Rule Book.


There is a video from each of the three presentation nights.  Additionally, the document below contains the various chat questions answered from the clinic.     

These clinics were designed to provide an understanding and in-depth knowledge of the rules for Little League Baseball. We formatted the clinics in a way that benefit all Board Members, Managers, Coaches, Parents and Umpires. Little League Baseball has made changes in the 2021 rules. We reviewed each of the rule changes along with other key rules to prepare everyone for the upcoming 2021 season.   Enjoy the videos;
