South Milwaukee Preseason ID: Blast Motion Board


Kevin Cronin
Tech Analyst, Area Scout

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.

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)

Rank Name State School Class Pos Bat Speed (avg)
1 Jaxon Clayton WI Brookfield Central 2025 3B 76.3 mph
2 Chris Calico WI West Salem 2023 OF 76.0 mph
3 JT Kelenic WI Catholic Memorial 2023 OF 75.6 mph
4 Ben Flerlage IL Latin School of Chicago 2023 OF 75.0 mph
5 TJ Schuyler IL Antioch 2023 C 73.6 mph
6 JD DIX WI Whitefish Bay 2024 SS 73.0 mph
7 Ethan Moore IL Oak Park-River Forest 2025 SS 72.5 mph
8 Jason Adix WI University School of Milwaukee 2023 3B 72.1 mph
9 Cade Palkowski WI Oak Creek 2024 OF 71.7 mph
10 BOSTON HALLORAN WI Franklin 2023 3B 71.4 mph

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.

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.
