Wausau Summer ID: Pitching Data Dive

July 28, 2026
By: Anthony Jablonski
Prep Baseball Wisconsin Staff

On July 7th, the Prep Baseball Wisconsin staff hosted the Wausau Summer ID at Athletic Park in Wausau, 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:

SPIN RATE (AVG.)

Rank Name State School Class Pos Spin Rate (avg)
1 Wyatt Beaudoin WI Amherst 2028 3B 2438 rpm
2 Masyn Wormet WI Stevens Point Area 2027 LHP 2363 rpm
3 Daniel Matson WI Adams-Friendship 2027 LHP 2207 rpm
4 Pierson Hacker WI Kimberly 2027 OF 2139 rpm
5 Koltyn Stevens WI Marathon 2029 SS 2109 rpm
6 Gabe Seis WI Adams-Friendship 2029 RHP 2075 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 Eli Yochem WI Slinger 2031 3B 22.2 in
2 Koltyn Stevens WI Marathon 2029 SS 18.1 in
3 Pierson Hacker WI Kimberly 2027 OF 17.6 in
4 Gabe Seis WI Adams-Friendship 2029 RHP 16.5 in
5 Easton Brooks WI Mosinee 2028 LHP 15.7 in
6 Masyn Wormet WI Stevens Point Area 2027 LHP 15.0 in
7 Wyatt Beaudoin WI Amherst 2028 3B 14.0 in
8 Daniel Matson WI Adams-Friendship 2027 LHP 12.1 in
9 Camdyn Rye WI Wausau East 2028 SS 11.3 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 Tommy Gagnon WI Wittenberg-Birnamwood 2027 LHP -13.3
2 Masyn Wormet WI Stevens Point Area 2027 LHP -10.8
3 Pierson Hacker WI Kimberly 2027 OF -10.3

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.”

STRIKE ZONE RATE%

1 Eli Yochem WI Slinger 2031 3B 50 %

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