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: 

TRACKMAN

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	2024	RHP	88.3 mph
3	Jacob Haughton	WI	Case	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	2024	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	Vel Phillips 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.)

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.)

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.”

STRIKE ZONE RATE%

Average MLB pitchers throw 62% strikes, and better pitchers throw strikes 65% of the time, or roughly 2:1 strikes to balls.
