My 9y old cant throw a correct 4sfb…meaning the rotation of the ball isnt like bottom to top. Ive tried everything but he just cant do it.
He has very good locationand above average velocity so thats not the issue…i just want him to throw correct and prevent any damages later on.
A couple of former triple a pitchers have said not to worry about it and some other instructors say its needs to be adressed before things get ugly.
So what can i do now?
Is it normal because of the size of the hands and all…will it develop eventually…should it already be developed?
Things weve done so far:
all the grips, slots and isolation drills.
it even seems he cant throw it with the elbow in the glove drill.
Where to go from here?
Do i need to worry about it or is this like very common of very uncommon?
