Screw ball and submirine pitchers

If any one out there are submirine pitchers you should read this. I read a article from a sports physician. He said that a screwball thrown underhand has as much stress on your arm as a slider thrown 3/4. Thats why so many softball pitchers throw a screwball. Maybe I throw submirine style :smiley:

It would make sense, I mean sub. and 3/4 ar basically opposite right?

I throw almost between a side armed pitch and a submarine so I may have to try a go alittle farther down on my pitching motion and try that screwball…
