Aurora Preseason ID: Blast Motion Board


Kevin Cronin
Tech Analyst, Area Scout

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.

Hand Speed (Peak & Average)

Rank Name State School Class Pos Hand Speed (max)
1 Michael Scarpelli IL Libertyville 2023 RHP 26.2 mph
2 Aiden Choslovsky IL Lincoln Park 2023 LHP 25.5 mph
3 Sam Rohlfing IL Harvest Christian Academy 2023 3B 25.0 mph
4 Daniel Blickhan IL West Chicago 2023 3B 24.9 mph
5 Joshua McGuigan IL Plainfield South 2023 OF 24.7 mph
6 Zach Polubinski IL Oswego East 2023 1B 24.6 mph

Rank Name State School Class Pos Hand Speed (avg)
1 Aiden Choslovsky IL Lincoln Park 2023 LHP 25.0 mph
2 Michael Scarpelli IL Libertyville 2023 RHP 24.8 mph
3 Daniel Blickhan IL West Chicago 2023 3B 23.9 mph
4 Sam Rohlfing IL Harvest Christian Academy 2023 3B 23.8 mph

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 Aiden Choslovsky IL Lincoln Park 2023 LHP 76.7 mph
2 Nick Mardis IL Bloomington Central Catholic 2023 C 75.4 mph
3 Josh Polubinski IL Oswego East 2023 3B 73.7 mph
4 Sam Rohlfing IL Harvest Christian Academy 2023 3B 72.4 mph
5 Taylor Kujak IL Plainfield Central 2023 SS 71.7 mph
6 Daniel Blickhan IL West Chicago 2023 3B 71.5 mph
7 Zach Polubinski IL Oswego East 2023 1B 70.8 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.

Rotational Acceleration (Peak & Average)

Rank Name State School Class Pos Rot. Acc (max)
1 Josh Siberz IL Plainfield North 2023 OF 31.2 g
2 Joshua McGuigan IL Plainfield South 2023 OF 29.1 g
3 Mike Polubinski IL Oswego East 2023 OF 28.2 g
4 Michael Scarpelli IL Libertyville 2023 RHP 27.4 g
5 Josh Polubinski IL Oswego East 2023 3B 26.8 g
6 Marvin Guzman IL Bolingbrook 2023 SS 25.5 g
7 Brandon Pflomm IL Hersey 2024 LF 24.6 g

Rank Name State School Class Pos Rot. Acc (avg)
1 Josh Siberz IL Plainfield North 2023 OF 27.0 g
2 Mike Polubinski IL Oswego East 2023 OF 24.7 g
3 Joshua McGuigan IL Plainfield South 2023 OF 24.1 g
4 Josh Polubinski IL Oswego East 2023 3B 23.6 g

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.
