South Milwaukee Preseason ID: Pitching Data Dive

Tech Analyst, Area Scout

On Mar. 5th, the PBR Wisconsin team hosted its latest event along the 2023 winter showcase circuit, the annual South Milwaukee Preseason ID at Hitters Baseball Academy in Caledonia, Wis. Nearly 80 players made it out to this event, providing us with updated looks and a new list of prospects to follow in an area of Wisconsin that regularly produces some of the state’s top talent.

Last Friday, we took a closer look at some of the immediate standouts who caught our attention with our Quick Hits. we published our Statistical Analysis on Friday, where we broke down the stat leaders from the more traditional categories. Today, we will take a further in-depth look at the top pitchers with the help of our tech partnerships, broken down by the categories down below:

FASTBALL

VELOCITY (MAX)

Rank Name State School Class Pos Velocity (max)
1 Ethan Bauerschmidt WI Tremper 2025 SS 90.1 mph
2 Adam Urban WI Wauwatosa West 2025 RHP 88.3 mph
3 Jacob Haughton WI Case High 2025 RHP 87.9 mph
4 Abe Herchenbach WI Elkhorn 2025 RHP 84.8 mph
5 Cashton Jones WI Madison Memorial 2024 RHP 84.7 mph

Max Fastball Velocity: This metric calculates the speed of the pitch as it’s released from the pitcher’s hand.

SPIN RATE (AVG.)

Rank Name State School Class Pos Spin Rate (avg)
1 Grant Manthei WI Lake Country Lutheran 2026 C 2519 rpm
2 Adam Urban WI Wauwatosa West 2025 RHP 2275 rpm
3 Ethan Bauerschmidt WI Tremper 2025 SS 2264 rpm
4 Joseph Suokko WI Westosha Central 2025 1B 2198 rpm
5 Ezra Liggon WI Madison Memorial 2026 OF 2157 rpm

Spin Rate: This metric calculates the rate of spin on the baseball as it leaves the pitcher’s hand, measured in revolutions per minute (rpm). Historical data shows that high-spin fastballs lessen the impact of gravity, allowing for more ‘rise’ (or less fall, in other words) as it carries through the zone. Low-spin fastballs typically indicate the pitch has greater horizontal action, often making it tougher to square up, but generally easier to make contact with, leading to more ground balls, while high-spin fastballs show a correlation with swings and misses.

INDUCED VERTICAL BREAK (AVG.)

Rank Name State School Class Pos IVB (avg)
1 Brady Mohns WI Brookfield Central 2026 3B 19.8 in
2 Noah Grosspietsch WI Madison Memorial 2024 1B 19.4 in
3 Colton Angell WI Oshkosh North 2024 3B 18.9 in
4 Bryce Stasik WI Port Washington 2024 OF 18.8 in
5 Sean Justham WI Wauwatosa West 2025 RHP 18.8 in
6 Cameron Carter WI Arrowhead High 2026 RHP 18.4 in
7 Bennett Schueller WI Franklin 2026 RHP 18.3 in
8 Owen Walsh IL St Ignatius 2025 RHP 17.9 in
9 Peter Idleman WI University School of Milwaukee 2024 RHP 17.1 in
10 Grant Manthei WI Lake Country Lutheran 2026 C 17.0 in

Induced Vertical Break: Used in short form as "IVB," this metric is most important on fastballs for creating rise and on curveballs for creating depth – it can also have some use when measuring sliders and cutters as well. Sliders tend to be closer to zero inches while cutters are generally between 5 and 15 inches. Usually fastballs and curveballs with large IVB have higher spin efficiencies as well. Sliders generally have very little (closer to zero) IVB and very low spin efficiency. You could also categorize IVB into spin rate as this is part of the “useful movement” you’re looking for. IVB is also a huge part of the vertical approach angle.

HORIZONTAL MOVEMENT (AVG.)

Rank Name State School Class Pos HM (avg)
1 Charlie McIntyre WI Whitefish Bay 2026 CF -19.2
2 Carson Consigny WI Arrowhead 2025 OF 17.7
3 Abe Herchenbach WI Elkhorn 2025 RHP 17.3
4 Peter Idleman WI University School of Milwaukee 2024 RHP 16.9
5 Carter Valleskey WI Valders 2026 RHP 15.0

Horizontal Break: Outlined on TrackMan’s own website: “... horizontal movement is measured in inches between where the pitch actually crosses the front of home plate side-wise, and where it would have crossed home plate side-wise if had it traveled in a perfectly straight line from release. A positive number means the break was to the right from the pitcher’s perspective, while a negative number means the break was to the left from the pitcher’s perspective.”
