West Milwaukee Preseason ID: Positional Data Dive


By. Josh Fields
Area Scout, Data Coordinator

On Feb. 17th, the Prep Baseball Wisconsin staff hosted the West Milwaukee Preseason ID at STiKS Academy in Waukesha, 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:

10 Graiden Liethen WI Arrowhead 2025 RHP 21.6 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 Nathan Schopf WI Oak Creek 2025 OF 78.3 mph
2 Logan Zaverl WI Germantown 2025 RHP 77.4 mph

9 Preston Manthei WI Lake Country Lutheran 2025 3B 73.3 mph
10 Ethan Daily WI Waukesha North 2026 3B 73.3 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 Ethan Daily WI Waukesha North 2026 3B 28.3 g
2 Nolan Hanson WI Arrowhead 2027 RHP 27.1 g
3 Matthew O'Grady Jr. WI Badger 2026 OF 22.6 g

7 Charlie Slawinski WI Brookfield East High 2025 SS 18.7 g
8 Charlie Hoven WI Whitefish Bay 2026 3B 17.9 g
9 Nathan Schopf WI Oak Creek 2025 OF 17.7 g
10 Graiden Liethen WI Arrowhead 2025 RHP 17.3 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

EDGE SCORE

Rank Name State School Class Pos Edge Score
1 Andrew Carlson WI Neenah 2025 3B 81.63
2 Brock Goral WI Waukesha West 2025 OF 80.99
3 Cail Geiger WI Menomonee Falls 2026 RHP 80.98
4 Nick Gilroy WI Arrowhead 2025 OF 80.01
5 Luke Schlosser WI Oconomowoc 2025 2B 79.91
6 Jackson Reno WI Oconomowoc High 2025 OF 79.84
7 Marek Wawrzyniakowski WI Catholic Memorial 2025 C 79.73
8 Colton Semmelmann WI Brookfield Central 2026 LHP 79.13
9 Dean Staudacher WI Muskego 2025 SS 79.04
10 Matthew Koo WI Whitnall 2025 C 78.78

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.
