But to answer your question, I would say 3 pitches, with none of them being any that put unnecessary or unneeded torque on the elbow or shoulder. 2 seam, 4 seam, changeup, and/or split finger. In 9 year old ball, if someone can throw all of those with great command, then he is above the curve. On the same token, if any 9 year old can hit those pitches, he is above the curve too.
