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 develop their skills before advancing to Major 70 in the seasons that follow. The players at the Major 60 level include all 10 year-olds. The 11 year-old players at MMB are divided between the Major 60 and Major 70 levels upon consideration of the evaluations of previous years and conversations with their previous managers.
