Western Wisconsin Summer ID: Pitching Data Dive

August 17, 2026
By: Anthony Jablonski
Prep Baseball Wisconsin Staff

On July 14th, the Prep Baseball Wisconsin staff hosted the Western Wisconsin Summer ID at Valley Sports Academy in Lake Hallie, 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. Also, we released our Takeaways 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:

FASTBALL

VELOCITY (MAX)

Rank Name State School Class Pos Velocity (max)
1 Maxwell Jaeger WI Menomonie 2027 SS 81.3 mph
2 Anthony Berends WI Baldwin-Woodville 2028 RHP 79.9 mph
3 Henry Pommier WI St. Croix Central 2029 RHP 79.7 mph
4 Maxel Keyes WI Menomonie High 2029 3B 78.5 mph
5 Josh Wright WI Fall Creek 2027 OF 78.5 mph

SPIN RATE (AVG.)

Rank Name State School Class Pos Spin Rate (avg)
1 Oliver Sullivan WI Menomonie 2029 OF 2249 rpm
2 Charlie Bowe WI Bloomer 2028 RHP 2037 rpm
3 Josh Wright WI Fall Creek 2027 OF 1976 rpm
4 Maxel Keyes WI Menomonie High 2029 3B 1927 rpm
5 Zach Konkel WI Mondovi 2027 3B 1905 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 Anthony Berends WI Baldwin-Woodville 2028 RHP 15.1 in
2 Josh Wright WI Fall Creek 2027 OF 14.3 in
3 Micah Johnson WI Hudson 2029 SS 13.7 in
4 Charlie Bowe WI Bloomer 2028 RHP 12.8 in
5 Oliver Sullivan WI Menomonie 2029 OF 11.9 in
6 Gavin Mittlestadt WI Menomonie 2029 SS 11.1 in
7 Maxel Keyes WI Menomonie High 2029 3B 10.6 in
8 Zach Konkel WI Mondovi 2027 3B 10.3 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.)

Rank Name State School Class Pos HM (avg)
1 Micah Johnson WI Hudson 2029 SS 14.5
2 Maxwell Jaeger WI Menomonie 2027 SS 14.1
3 Maxel Keyes WI Menomonie High 2029 3B 12.8
4 Henry Pommier WI St. Croix Central 2029 RHP 11.8
5 Gavin Mittlestadt WI Menomonie 2029 SS 11.5

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.
