Prep Baseball Report

Team Arizona: Rotational Acceleration

Brett Thorney
State Scouting Director


One of the important tools Prep Baseball Report is starting to implement 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.

At the 2020 PBR Future Games, all hitters were hooked up to blast sensors for there on the field BP rounds during their individual showcases workouts. We were able to collect valuable swing & impact metrics on many of the top uncommitted players in the country. We will be able to share this data with coaches & scouts from around the country as well as help players identify areas of development.

Below will you get a look in how #TEAMARIZONA stacked up when measuring Rotational Accleration using the Blast Motion sensors:


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
