28 players from the Mid-Atlantic Dirtbags organization participated last Sunday in a Scout Day at the Gilman School. Players were put through a pro-style workout and threw bullpens in front of our PBR Maryland staff with Blast and TrackMan on hand to capture and record data.
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.

BLAST MOTION DATA
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
AVERAGE 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
AVERAGE HAND SPEED
MLB Avg: 23-29 mph | College Avg: 21-24 mph | HS Varsity Avg: 19-22 mph
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
AVERAGE ROTATIONAL ACCELERATION
MLB Avg: 16.8 g | College Avg: 12.9 g | HS Varsity Avg: 9.9 g
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%
