South Milwaukee Preseason ID: Blast Motion Board
March 10, 2022
On March 6, PBR Wisconsin hosted its longest running annual event on its winter calendar, the South Milwaukee Preseason ID at Hitters Baseball Academy in Caledonia, Wis. Approximately 90 players, mostly from Southeastern Wisconsin, attended this event, many of whom have established themselves as high-level prospects in the state. This event also perennially provides our staff with a glimpse at the future, allowing us to gain a clearer understanding of the up-and-coming players in Wisconsin, specifically the Class of 2025.
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 quick statistical analysis of those that participated in the event. 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.
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.
