Data collected by TrackMan has become significantly important for high school, Juco, and 4-year players. College programs have evolved beyond radar velocity readings, looking deeper into a pitcher's ability to spin and move the ball. In addition to velocity, TrackMan provides pitchers with valuable data points such as spin rate, spin direction, horizontal movement, vertical movement, and more. Ultimately providing feedback to college coaches, MLB scouts, and the players themselves; to enhance training and also to identify prospects of interest above and beyond simple velocity readings.
At PBR California showcases and events, amateur players now have access to the same technology shared by professionals and are able to see how their pitching arsenal compares with those across the state and the country. The TrackMan Arsenal Analysis will highlight those metrics and explain the benefits behind the numbers.
