MSHYB operates a recreational baseball league for girls and boys between the ages of 6 and 12, who are in at least first grade.

Our league is structured based on a combination of age and baseball ability and experience, with a focus on balancing safety, competitiveness and fun.

Players are placed with teams based on their ability and experience, and have the opportunity to "play up" at higher levels via a call-up system modeled on professional baseball organizations.

Teams are organized into a chain system, which is described below.

For more advanced players seeking higher levels of competition, MSHYB also offers a travel baseball program.
