Little league pitching velocity

Question
Is there published data on 10-13 yo pitching velocities. I find as a pitching
coach, managers in Little league have unrealistic expectations. Where are these
70 plus mph 12 yo?  I do not see them but coaches continue to push.

Answer
There is no data regarding that type of information.  It is nuts for coaches to push velocity in young kids but it is played up on ESPN and the LL world series.  Plus coaches say unrealistic things like my 11 yo throws 75 mph.  It doesn't happen.  Tom Glavine doesn't even throw 85 anymore. Don't worry about the velocity, just work on control.
