VALLEJO, CALIF. - The Show California Scout Day brought 60+ players (2021 - 7; 2022 - 23; 2023 - 15; 2024 - 16; 2026 - 1) out to take part in the showcase where players were put through a standard showcase workout that included the 60-yard sprint, round of batting practice, defensive workouts at respective positions, and concluded with bullpen sessions where the pitchers' stats were compiled.
Note: All showcase videos have been added to their profiles
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 each swing taken by each prospect at the event. Some of the metrics collected include: Bat Speed, On Plane Efficiency, Peak Hand Speed, Power and Rotational Acceleration. Those metrics are published in this piece.
Each player has their Blast Motion metrics 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.
NOTE: Each player had one round of BP and upwards of 10 swings.

Average On-Plane Efficiency
Measures the percentage of your swing where the bat is on the swing plane. Your vertical bat angle at contact establishes the plane for that swing. Plane is a great indicator for making more consistent contact on the barrel of the bat. For more info: On-Plane Efficiency

Max Rotational Acceleration
Measures how quickly your bat accelerates into the swing plane. Rotation is a good indicator of how you build bat speed by sequencing properly. The quicker your rotational acceleration, the more power you will have and the more time you have to adjust to pitch locations. For more info: Rotational Acceleration
