Rookies A is intended for girls and boys ages 6-7 years old. In Rookies A, a pitching machine is used to provide players an accurately pitched ball with consistent speed. Batters will receive a set number of hittable pitches from the pitching machine in each at-bat; if they are unsuccessful in hitting the ball in play, a batting tee is used.

Games are six innings in length with the customary three outs per half inning. Scoring is limited within each half inning; if a team reaches the run limit with the inning, the inning will be ended and the opposing team will come to bat.

Games are played on a Little League sized field with 60' between each base and a pitching rubber set 45' from home plate.

Players in this division are placed on team rosters by division commissioners according to their skill set.
