In the Mt Gravatt eagles, there is a kid named Danny who can do perfect pitches and his fastest was 86mph during training and 80mph during a game.
Honestly, it varies. I've seen short little league pitchers that are the best. But speaking from what experts would say, the upper 5 feet, 5'8, 5'9, etc. Less then that as well, though. If your a little league pitcher, or your son is, don't let the lack of height get you down. Anything is possible.
