Tee Ball Baseball 
Tee Ball Baseball is for boys and girls 4-5 years old (with a local option for 6- and/or 7-year-olds) who want to learn the fundamentals of hitting and fielding. In Tee Ball, players hit a ball off a batting tee. Rules of the game may be varied to accommodate the need for teaching. The primary goals of Tee Ball are to instruct children in the fundamentals of baseball and to allow them to experience the value of teamwork. Rosters may be composed of between 12 and 20 players, but most leagues have rosters in the 12-15 range. No live pitching is permitted in this division. Generally, the diamond used is a 60-foot diamond, but the league has the option to use a 50-foot diamond. 

Minor League Baseball (Coach Pitch, AA, AAA) 
Minor League Baseball programs for boys and girls may be operated within each division for younger players with less experience. The minor league may be players ages 7-12. Divisions may be established within the Minor League for "machine pitch," "coach pitch" or "player pitch." By local option, a player who is league age 6 for the current season and has played a year in Tee Ball may be "moved up" to a coach pitch division. A local league might have its 7-8-year-olds in the Minor League Coach Pitch Division, while its 9-10-year-olds are in the Minor League Player Pitch Division. However, by local option, some of the 9-year-olds could "play down" in the coach pitch division, and some of the 8-year-olds could "play up." This is entirely the choice of the local league board of directors. Rosters may be composed of between 12 and 20 players, but most leagues have rosters in the 12-15 range. The diamond used is a 60-foot diamond and the pitching distance is 46 feet.
