About Spin Doctor

Proper mechanics is defined by a pitcher in which he can deliver a quality pitch, with a minimum amount of exertion and attain maximum results. If you can achieve this result you will be on your way to being a successful pitcher. All of the college and Professional scouts look for different and subjective qualities in which they make their assessments. However, there is one common trait that they all look for: A consistent, effortless, repeatable delivery. My initial and most important focus is to do just that. Mold and shape each pitcher on their mechanics so that they can effectively deliver a quality pitch. More important than the actual pitch is the hard work that it took to get the body in a strong, consistent and balanced posture in order to deliver that pitch. Once you attain your sound delivery then the rest is easy. Learning how to make the ball move in a variety of ways (i.e. breaking balls, change ups, cutters, etc.) is the easiest thing that I teach.

My goal is simple: One delivery, multitude of pitches.
