LATHROP, CALIF. - We ran the NorCal Underclass Game last weekend at Islanders Field and the event had some exciting and talented young players on hand, including some pitchers ready to shine this coming spring season. Today we publish the pitching data gathered with the portable TrackMan B1 unit, during live game action.
Prep Baseball Report California events across the country have been powered by TrackMan’s industry-leading portable system to capture pinpoint accurate, actionable data from player performances. Prep Baseball Report and TrackMan are dedicated to recognizing talent and unleashing their potential.
At the event all pitchers pitches were monitored through the portable Trackman B1 unit. Each player threw their complete arsenal of pitches allowing us to collect metrics such as release velocity, spin rate, vertical & horizontal movement and much more.
This data goes directly into the player profiles allowing the PBR Staff, college coaches and professional scouts alike to evaluate and compare prospects on a national scale.
Some of the advanced metrics gathered, available for subscribers to PBR Plus: effective velocity, max & avg IVB, max & avg horizontal movement, extension avg, release height avg, zone %
Spin Rate is defined as how fast the ball is spinning as it leaves the pitcher's hand, measured in "Revolutions per Minute or RPM"
We will roll out more content, including the reports, in the coming weeks.
