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.

CATEGORICAL LEADERBOARDS (2021/2022 grads)

Max Bat Speed

Bat Speed is the observed speed of the sweet spot of the bat at impact. For more info: Blast Bat Speed

MLB Avg: 66-78 mph | College: 66-75 mph | HS Varsity: 60-70 mph

Avg. Bat Speed

MLB Avg: 66-78 mph | College: 66-75 mph | HS Varsity: 60-70 mph

Max Hand Speed

Peak Hand Speed is the observed maximum speed as measured on the handle of the bat (measured six inches from the knob of the bat). Peak Hand Speed will occur prior to the moment of impact, very close to the commit time in the swing when the wrists unhinge. For more info: Peak Hand Speed

MLB Avg: 23-29 mph | College Avg: 21-24 mph | HS Varsity Avg: 19-22 mph

Avg. Hand Speed

MLB Avg: 23-29 mph | College Avg: 21-24 mph | HS Varsity Avg: 19-22 mph

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

Ideal Efficiency %: 70% or Higher | Range: 65%-85%

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

MLB Avg: 16.8 g | College Avg: 12.9 g | HS Varsity Avg: 9.9 g

Avg. Rotational Acceleration
