Joliet Preseason I.D.: Blast Motion Board

On March 28, the PBR Illinois team hosted this first-ever Joliet Preseason I.D. at the new Rhino Baseball Academy in Shorewood, Ill. The event marked the end of our high school winter showcase circuit, and around 120 players from the area participated.

Shortly after the event's conclusion we published a Quick Hits piece highlighting the top performances from the day and followed that up by taking a look at things from a numbers perspective within our Statistical Analysis.

We previously published our TrackMan Files, looking at the pitch metrics and batted ball data from the event, and today, with the help of our Blast Motion sensors, we're analyzing the swing metrics measured on Saturday at this high-caliber showcase.

HAND SPEED (PEAK & AVERAGE)

Peak Hand Speed: 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.

BAT SPEED (AVERAGE)

Bat Speed: The observed speed of the sweet spot of the bat at impact. The sweet spot of the bat is measured six inches from the tip of the bat.

ROTATIONAL ACCELERATION (PEAK & AVERAGE)

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.
