Tee Ball: 4-6 years
This is for boys and girls 4-6 years old who want to learn the fundamentals of hitting and fielding. The primary goals of Tee Ball are to instruct youngsters in the fundamentals of baseball and softball and allow them to experience the value of teamwork but most of all, to have fun.

Rookies (Machine Pitch or Coach Pitch) Baseball or Softball (ages 6-8)
This division is designed to expand on the fundamental skills while introducing the basic rules of baseball or softball.  Players will learn fundamental skills involved in hitting, throwing and catching. Many skill levels will be represented and no prior experience is required. League Age 9 may be considered with no prior baseball experience. This division will strive to provide balanced playing time for all players and a continuous batting order will be used. Softball players will play games with teams from other little leagues in our area.  Parents are strongly encouraged to become involved in this introductory level of Little League.  After completing a Little League volunteer application and passing a required national background check, parents may become involved in practices, and be eligible as coaches, managers, umpires, local league board members and other volunteer positions within the league.
