PBR Maryland hosted its annual Maryland Top Prospect Games at Joe Cannon Stadium on July 11th. Close to 50 players from across MD, DE and VA participated in a pro-style workout in front of our PBR Maryland and Mid-Atlantic staff.
One of the important tools Prep Baseball Report has implemented at its events is the use of Blast Motion sensors. During batting practice, the Blast Motion sensors measure Swing and Impact Metrics across several categories. Swing metrics measure pre-impact mechanics centered around plane, connection, and rotation while impact metrics measure pre-impact performance outcomes based on ball contact.
With the Blast Motion sensor, we were able to collect data from every swing taken by each prospect registered to receive data as part of their package at the event. Below is the full release of the Blast Motion metrics collected including: Bat Speed, On Plane Efficiency, Peak Hand Speed, and Rotational Acceleration.
The Blast Motion metrics are also uploaded into their profiles following the completion of the event providing insight into areas that could be improved upon as well as helping paint a clear picture of the player to the college and professional scouts doing their research on prospects they may be interested in.
