Prep Baseball Report

Milwaukee Fall ID: Positional Data Dive


Kevin Cronin
Illinois & Wisconsin Data Coordinator, Area Scout

On September 24th, the Prep Baseball Wisconsin staff hosted the Milwaukee Fall ID at The Rock Sports Complex in Franklin, WI. Over 15 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 Wisconsin staff.

We've already posted a Statistical Analysis from the event, highlighting more of the traditional statistical categories. Later in the week we will release our Takeaways, highlighting some of the event's top performers.

Today, we will take a further in-depth look at the top positional players with the help of our tech partnerships, broken down by the categories down below:

The ability to develop force quickly is a requisite ability in most sports. The Reactive Strength Index (RSI) has been developed as a measure of explosive strength and is derived by evaluating jump height divided by ground contact time during the depth jump. Regarding Vertical Jumps and its application to baseball, there have been studies conducted that show a correlation between max jump height for an athlete and their ability to generate power and strength, especially on the mound.

Exit Velocity: This metric measures the speed of the ball, measured in miles per hour, as it comes off the bat at the moment of contact.

Batted Ball (MAX)

Rank Name State School Class Pos Distance (max)
1 Brayden Alivo WI St. Thomas More 2026 SS 347 ft
2 Owen Sather WI Living Word Lutheran 2026 C 333 ft
3 Jack White WI Living Word Lutheran 2026 3B 325 ft
4 Mason Beaver WI East Troy 2026 OF 321 ft

Sweet Spot %

Rank Name State School Class Pos Sweet Spot %
1 Callahan Connor WI Marquette University 2027 C 77 %
2 Cameron Palmgren WI Case High 2029 RHP 63 %
^ Brayden Alivo WI St. Thomas More 2026 SS 63 %
3 Everett Sachs WI Preble 2027 SS 55 %

Sweet Spot percentage: This metric is determined by how often the player produces a batted ball during the session with a launch angle between 8 to 32 degrees.


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 Austin Johnson WI Port Washington 2028 SS 21.3 mph
2 Aaron Prusko WI Wauwatosa West 2028 RHP 20.2 mph
3 Cameron Palmgren WI Case High 2029 RHP 20.2 mph
4 Gavin Vahl WI Whitnall High 2029 2B 20.2 mph
5 Jack White WI Living Word Lutheran 2026 3B 19.4 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 Brayden Alivo WI St. Thomas More 2026 SS 68.3 mph
2 Jack White WI Living Word Lutheran 2026 3B 64.6 mph
3 Lucas Reinheimer WI The Prairie School 2029 RHP 64.5 mph
4 Austin Johnson WI Port Washington 2028 SS 64.4 mph
5 Owen Sather WI Living Word Lutheran 2026 C 63.7 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 Collin Mueller WI Whitnall 2029 SS 15.0 g
2 Mason Beaver WI East Troy 2026 OF 14.1 g
3 Cameron Palmgren WI Case High 2029 RHP 13.5 g
4 Brayden Alivo WI St. Thomas More 2026 SS 13.0 g
5 Jack White WI Living Word Lutheran 2026 3B 11.0 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.

ON-PLANE EFFICIENCY %

Rank Name State School Class Pos On Plane Eff (avg)
1 Mason Beaver WI East Troy 2026 OF 87 %
2 Cameron Palmgren WI Case High 2029 RHP 86 %
3 Collin Mueller WI Whitnall 2029 SS 78 %
4 Owen Sather WI Living Word Lutheran 2026 C 72 %
5 Brayden Alivo WI St. Thomas More 2026 SS 64 %

On-Plane Efficiency %: measures the percentage of your swing where the bat is on the swing plane. Your Vertical Bat Angle (VBA) at contact establishes the plane for that specific swing. A high % is a great indicator of making consistent contact and barreling balls. Blast recommends an average of 70% or higher, with a range in the 65% to 85%.


VISUAL EDGE

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

EDGE SCORE

Rank Name State School Class Pos Edge Score
1 Austin Johnson WI Port Washington 2028 SS 71.71
2 Gavin Vahl WI Whitnall High 2029 2B 71.36
3 Owen Sather WI Living Word Lutheran 2026 C 70.89
4 Cameron Palmgren WI Case High 2029 RHP 70.20
5 Callahan Connor WI Marquette University 2027 C 69.95

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.
