Arm interventions

Does any body have any objective data on arm interventions before
there was a DL and before pitch counts were the norm in the MLB?

what do you mean by arm intervention

For example, anykind of professional help in the the way surgery, rehab, or perscribed rest for an extended period.


You are going to have to explain that a lot better because I have no idea what you are trying to ask…

Is there any offical record of how many arm injuries there were to pitchers ? Say, from 1965 to 1975.

I would imagine that there would be, but that would through the use of some sort of DL would it not?

Have you thought aboust asking STATS inc?

Ah, gotcha. But I have no idea. Sorry!
