Blast Motion Reports: Dirtbags Scout Day

Jason Burton
Richmond Scouting Coordinator

On June 25th the Dirtbags and PBR VA/DC held a Scout Day at the Lynchburg Hillcats Stadium in Lynchburg, VA. There were over 140 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

 Jake Moore  Chatham  2023  Liberty  69.2 mph
 Evan Stone  Dutch Fork (SC)  2021    69.2 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

 Gavin Bralley  Atlee  2021    22.8 g
 Sam Bell  Jefferson Forest  2023    22.6 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%

Name School Class Commitment Average On Plane Efficiency (%)
 Chase Mallory  William Monroe  2021    93 %

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

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
