The New Moneyball: How Ballpark Sensors Are Changing Baseball

Advancements in the capability of sensors, processors, and storage devices have led to an explosion in the amount of data that is captured during sporting events. The Statcast system, for example, uses Doppler radar and stereoscopic video from two arrays of high-resolution optical imagers to acquire seven terabytes of data during each Major League Baseball (MLB) game. One use of these data is to enhance the experience of sports fans. As a case in point, Statcast data are used to generate information and visualizations that are disseminated in real time through telecasts and other media such as an app which displays pitch parameters derived from sensor measurements.
