ZLL does not honor requests to move players up to higher divisions. All players are required to undergo evaluations. Evaluation scores are used by managers in the 50/70, Majors, and Minors divisions to draft their teams. If your son was not selected into the division that you expected, it is likely he did not score as high at evaluations compared to his peers.
ZLL is confident in our evaluation process and understand disappointment is common in this situation. We encourage you to be supportive of your son and see this as an opportunity for him to pitch, catch, and play the infield positions that he likely would not be playing in the higher division.
