Aurora Preseason ID: Blast Motion Board
February 10, 2022
On Feb. 5, the PBR Illinois team hosted the Aurora Preseason ID at the Sport Zone in Aurora, Ill. This open event featured players from the 2022-25 high school grad classes, providing our staff with an ample opportunity to learn more about the area’s baseball talent.
Earlier this week we published Quick Hits highlighting the top prospects of the event by class. We also rolled out a Statistical Analysis, bringing you a look at the traditional stats collected in the showcase setting. We then dove deep into the data, looking at the pitch metrics and batted ball numbers from this event inside our TrackMan Files piece.
Today, with the help of our Blast Motion sensors, we're analyzing the swing metrics measured on Saturday at this high-caliber showcase.

Body Rotation: A swing that has the appropriate relative contributions of body and bat rotations is an efficient and Powerful swing that maintains proper sequencing. An efficient baseball swing is one in which the body creates the initial movements, which is then transferred to the arms and out to the bat, thereby maximizing Bat Speed through this proximal-to-distal kinematic sequencing movement pattern.
