SANTA CLARA, CALIF. Players gathered at Mission College on Jan. 27 for the NorCal Preseason All-State. They went through a traditional scout-style workout with running, jumping, fielding, and hitting portions. Pitchers threw bullpens monitored by TrackMan. All participants in the event had data collected by Prep Baseball's technology partners: TrackMan, Swift Technologies, and Blast. This data can be used to assess strengths and weaknesses in a player's game to highlight areas for improvement.

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.

Max Slider Velocity

Sliders generally are faster than most other off-speed pitches with less overall movement. This metric measures the speed of the slider when it comes out of the hand.

1 Chase McGill CA California 2025 RHP 81.1 mph
2 Gino Cappellazzo CA St. Francis 2026 C 77.8 mph

1 Luke Kaiser CA Folsom 2025 RHP 2570 rpm
