A DVS Score is a numerical value that quantifies the relative risk and performance potential associated within your pitching delivery. The DVS System begins and ends with the DVS Score. We require all clients to set up an initial evaluation to receive their DVS Score. Once a DVS Score has been produced we can properly provide a recommendation on a plan moving forward and get work on improving a client's DVS Score, health, and performance. A DVS Score is a numerical value that quantifies the relative risk and performance potential associated with any pitcher’s delivery.
