Coach JP says..
MEASURING PITCH SPIN IS REVOLUTIONARY... USE IT TO YOUR ADVANTAGE!
The greater the spin rate, the better your breaking ball. Whether your money pitch is a 12-6 curveball, a power curve or a slider you can get more bite and good late movement by increasing the rate of spin.
Pitcher's who can be fed this data are at a great advantage, it follows the same reasoning as why we all use a radar gun. Show them with numbers, quantify it, and they will buy into it. This is a buy-it-once and use-it-forever piece of training equipment. I only regret not offering it sooner.
