The league age determination date is the age a player as of August 31 of the current year/season.

CalSouth Little League is divided into several separate divisions or age groups.  Players are placed in the various Divisions (age groups), based upon the current league age determination date.

T-Ball - Ages 4 to 6
In T-Ball young kids are introduced to baseball. The youngsters learn, develop and practice fundamental baseball skills at an early age and receive maximum enjoyment from the experience. Emphasis is placed on participation and enjoying their first baseball experience. T-ball games are typically on a Monday/Wednesday or Tuesday/Thursday schedule. The registration fee includes a t-shirt, ball cap, team and individual picture, and an award at the end of the season.
For the upcoming season, T-Ball games will be held at the 3 grass diamonds adjacent to Mid-Sun Community Centre in Midnapore.

Rookie Ball (formerly "Coach Pitch") - Ages 6 to 8
In Rookie Ball the players will continue to develop their skills and learn the rules of baseball. Emphasis is placed upon hitting, base running, fielding/throwing and teamwork. Both offensive and defensive fundamentals are stressed.  Rookie games and practices are typically on a Monday/Wednesday/Saturday or Tuesday/Thursday/Saturday schedule. The registration fee includes a ball cap, team and individual picture, an award at the end of the season. All players receive a team jersey and belt that must be returned to the league at the end of the season.  Players supply their own grey pants.

Minors Division - Ages 9-10
Players are evaluated for the first time in Minors, for the purpose of drafting them onto teams by their coaches. In Minors, pitching to and by the players is introduced to become part of the game. As many players, as possible will be encouraged to pitch. Umpires in this division will allow a fairly liberal strike zone to encourage hitting. The object of the game is to get the ball hit into play as often as possible. Players are encouraged to play all positions throughout the season. This is the first age group where an All-Star structure team can continue with Tournament play after the season ends, if enough players are willing to participate. Typically, Minors have 2 games and 1-2 practices per week. Games and practices can be any day of the week. The registration fee includes a ball cap, team and individual picture, and an award at the end of the season. All players receive a team jersey and belt that must be returned to the league at the end of the season. Players supply their own grey pants.
