Mathewson McCarthy’s Major level is divided into two independent divisions, Major 60 and Major 70. There is no inter-division play between these two levels. Each division has different playing rules (with Major 70s rules being more advanced). Major 60 acts as a prep division for Major 70. Players at Major 60, which include all 10 year-olds, develop their skills before advancing to Major 70 in the seasons that follow.
