Green Bay Preseason ID: Pitching Data Dive

March 6, 2026

Area Scout & Content

On March 1st, the Prep Baseball Wisconsin staff hosted the Green Bay Preseason ID at Impact Sports Academy in De Pere, WI. Over 125 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. Also, we released our Quick Hits story, highlighting some of the event's top performers.

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:

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	Damian Philippi	WI	Brillion	2029	RHP	21.1 in
2	Landon Micolichek	WI	Preble	2027	RHP	19.5 in
3	Eli Shepard	WI	Freedom	2029	OF	18.9 in
4	Caden Blasczyk	WI	Ashwaubenon	2028	1B	18.7 in
5	Aksel Pocernich	WI	Slinger	2027	RHP	18.6 in
6	Josh Kelley	WI	West De Pere	2027	1B	18.4 in
7	Chance Carew	WI	New London	2029	LHP	18.0 in
8	Hank Nuetzel	WI	Wausaukee High	2028	SS	18.0 in
9	Brady Perrizo	WI	Preble	2027	RHP	17.9 in
10	Parker Sell	WI	West De Pere	2029	2B	17.6 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 efficiencies. 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 vertical approach angle.

HORIZONTAL MOVEMENT (AVG.)

10	Davis Zerjav	WI	West De Pere	2029	SS	15.3

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.”
