My 13 year old son threw 71mph with a very sore/tired arm and no mound, any idea of what his velocity would be if he fully rests his arm and uses a 9"-1ft mound?
is this according to a real gun or one of those places at a carnival or somthing where you throw into the net and it tells you how hard you threw becuase those things are rediculous
The way you phrase the question it sounds like you are looking for a scientific answer, which I am not qualified to provide.
Speaking in baseball terms their are so many different aspects to the art of throwing a baseball that I don’ think anyone can give you a reliable answer. The best way to know is to get your arm healthy again and then go out on the mound and see.
I’ll guess you will be a couple mph faster…
