Roger,
Welcome to the board.
I think you were the one who mentioned leaping.
Speaking ASA,
If the pitcher is a female, she must maintain contact with the
pitcher's plate or drag away with the pivot foot remaining in contact with the ground, just like it states in the rule book.
If the pitcher is a male, he may leap without penalty as long as the toes of the pivot foot remain pointing down.
In no case may any pitcher replant prior to releasing the pitch.
