Tee-ball for kids aged 4–12

Tee-ball is a fun and inclusive sport offering a simplified introduction to diamond sports in which every child can participate and develop fundamental skills in a supportive environment. Players hit the ball off a tee on a smaller diamond with a focus on learning batting technique (identical to a baseball swing), running and fielding skills (catching and throwing).

Suitable for players new to diamond sports and those interested in improving their defensive skills in a supportive environment.

Machine Pitch for kids aged 7–10

Machine Pitch (MP) is a modified form of junior baseball, where an adult uses a pitching machine to deliver consistent, safe and hittable pitches. As a first step in the transition from tee-ball to little league baseball, MP provides players with the confidence to hit a moving ball.

MP is recommended for players with previous diamond sport experience (at least 1 year tee-ball, softball or baseball), or if played in conjunction with regular Saturday morning tee-ball (U8, U9 or U10).

Little League (LL) and Intermediate League (IL) Baseball for kids aged 8–13

Little League (LL, 8–12) and Intermediate League (IL, 11–13) are the next step in a player's transition to baseball. Incorporating pitching into the game, it encourages further player skill development.

LL and IL are recommended for players with previous diamond sport experience (at least 1 year tee-ball, softball or baseball), or if aged 8–12, played in conjunction with regular Friday night tee-ball (U11 or U12).
