There is something I like to do that is not really a clinic but can be a great learning experience.
Go to a tournament that has multiple games at lots of leveles. But as a spectator not a coach.
watch the hitters watch how a team warms up. Observe how successfull teams interact with their coach.
Does every team have the same type defencive movement or is one way different?
And pitchers how many different styles do you see?
You can really learn alot by just observing.
