Eau Claire Preseason ID: Positional Data Dive


By. Josh Fields
Area Scout, Data Coordinator

On Feb. 10th, the Prep Baseball Wisconsin staff hosted the Eau Claire Preseason ID at Valley Sports Academy in Eau Claire, WI. Around 30 players participated in a pro-style workout, gathering unrivaled access to data through our state-of-the-art tech partners, as well as in-depth scouting analysis from our Prep Baseball Wisconsin staff.

Yesterday, we looked at the top measurable data performers from the event, found in our Statistical Analysis, where we broke down the stat leaders from the more traditional categories. Today, we will take a further in-depth look at the top positional prospects with the help from our tech partnerships, broken down by the categories down below:

BLAST

With the help of our Blast Motion sensors, we're analyzing the swing metrics measured at this open showcase.

HAND SPEED (AVERAGE)

Rank Name State School Class Pos Hand Speed (avg)
1 Cole Perlberg WI Chippewa Falls 2025 SS 23.0 mph
2 Brecken Boisvert WI Chippewa Falls 2025 LHP 22.9 mph
3 Ethan Sowieja WI Stanley-Boyd 2024 3B 22.7 mph
4 Logan Hagman WI Hudson 2027 C 22.4 mph
5 Grant Lokken WI Eau Claire Memorial 2025 OF 22.3 mph

Hand Speed: The observed 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 Logan Hagman WI Hudson 2027 C 77.0 mph
2 Isaiah Ahlberg WI Solon Springs 2026 C 74.3 mph
3 Clayton Kroschel WI Wayland Academy 2025 OF 73.7 mph
4 Cole Perlberg WI Chippewa Falls 2025 SS 71.9 mph
5 Kellen Smith WI Altoona 2025 SS 70.2 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 (AVERAGE)

Rank Name State School Class Pos Rot. Acc (avg)
1 Grayson Veenendall WI La Crosse Central 2026 C 23.5 g
2 Brecken Boisvert WI Chippewa Falls 2025 LHP 20.1 g
3 Henry Zimmermann WI River Falls 2024 OF 18.2 g
4 Ethan Sowieja WI Stanley-Boyd 2024 3B 17.0 g
5 Kellen Smith WI Altoona 2025 SS 16.8 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.

VISUAL EDGE

A look at the top Vizual Edge scores from the event.

EDGE SCORE

Rank Name State School Class Pos Edge Score
1 Henry Zimmermann WI River Falls 2024 OF 87.41
2 Grayson Veenendall WI La Crosse Central 2026 C 87.09
3 Ethan Dillingham WI Wis Rapids Lincoln 2026 RHP 82.81
4 Cole Perlberg WI Chippewa Falls 2025 SS 81.01
5 Clayton Kroschel WI Wayland Academy 2025 OF 79.41
6 Aiden Pankratz WI Eau Claire North 2025 OF 78.99
7 Joseph Garrison WI Altoona High 2024 2B 77.75
8 Eli Hazuga WI Stanley-Boyd 2024 1B 76.82
9 Grant Lokken WI Eau Claire Memorial 2025 OF 76.48
10 Brady Johnson WI Eau Claire Memorial 2025 RHP 76.16

The Edge Score is a comprehensive score out of 100 that takes the core-six visual skills into account, providing athletes, parents, coaches and scouts with a benchmark number for assessing an athlete’s overall visual ability. In general the higher the Edge Score, the higher chance of athletic success. Think of the Edge Score as the 'Sixth Metric' in the standard Five-Tools that make up a ball player.

The average Edge Score for the 2020 MLB Draft Class was 79.3 (of hitters who completed a Vizual Edge test). MLB players we've worked with typically show stronger scores, with elite hitters scoring consistently above 87.0 on their Edge Score.
