Abstract: A command measurement system employs a ball flight tracking system that measures the location of a ball as it breaks the plane of the strike zone. The command measurement system also employs an intended pitch location system that provides the pitcher with a wireless signal to inform the pitcher of the intended pitch location. This intended pitch location target forms the pitcher's intent of where he or she is trying to pitch the ball. The measured pitch location is compared to the intended pitch location and a measure of command is determined by the amount of deviation of the measured location from the intended pitch location.
