Thanks for all the advice guys I really do appreciate it.
JDfromfla - We have been doing the drills you have mentioned and yes we did start doing long toss this fall after his summer season was over. As it is getting colder here in the Midwest our time is going to be limited for a few months. We do have a gym that is about 100' long to throw in.
We did go to a pitching instructor when he turned 10 for about 4 lessons but for the most part it has just been me and him in the back yard. There is a local guy that is a NPA instructor. I have contacted him and he is going to work us in as soon as he has an opening.
Roger - How far from the wall should you start when doing the Hershiser drill?
topvelocity.net - I do see what you mean by sitting on the back leg and a friend of mine mention that to me as well. I think we could work on this doing the towel drill indoors this winter.
