On August 20th NOVA Premier and PBR VA/DC held a Scout Day at Dominion High School in Sterling, VA. There were 25 players in attendance for the event. During the event we compiled swing data and metrics from each player using our Blast Motion sensors. Below are some players who stood out on Blast.

Blast Motion:

During batting practice, the Blast Motion sensors measured 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. Below are the top performers in five of the categories measured using the Blast Motion sensors.

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 MiLB: 63-75 mph College: 66-75 mph

 

 

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 MiLB Avg: 12.6 g College Avg: 12.9 g

 

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%

 

Power:

The average Power generated during the swing is found from the effective mass of the bat, the Bat Speed at impact, and the average acceleration during the downswing. Power is measured in Watts. Higher Power is achieved when a hitter is able to swing a heavier bat and accelerate it to higher speeds. For more info: Power

MLB Avg: 3.65-5.65 kW MiLB Avg: 3.20-5.20 College Avg: 3.83-5.08

Rank	Name	State	School	Class	Position	Average Power (kW)
1	John McAleer	VA	Independence	2021	OF	4.64 kW
2	Wesley Clarke	VA	Marshall	2021	RHP	4.43 kW
3	Matthew Stevenson	VA	Stone Bridge	2021	1B	4.29 kW
4	Tony Franzonello	VA	Broad Run	2021		4.26 kW
5	Drew Petitt	VA	Briar Woods	2021	OF	4.18 kW
6	Joe Ferguson	VA	Broad Run	2021	C	4.16 kW
7	Joshua Kim	VA	Freedom (South Riding)	2021	SS	4.01 kW

 

Peak 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 MiLB Avg: 22-28 mph College Avg: 21-24 mph
