Appleton Summer ID: Pitcher Data Dive
July 12, 2024
On July. 9th, The Prep Baseball Wisconsin staff hosted: The Appleton Summer ID . Perennially, this showcase helps introduce our staff to new need-to-know players in the state that we’d not yet seen before, as well as provided us with updated looks at players who’ve earned our attention in the past.
Today, we will be looking at the top measurable data performers from the event, found below.

10 | Ian Butenhoff | WI | Wauwatosa West | 2026 | SS | 1931 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 | Zander Leick | WI | Kaukauna | 2025 | RHP | 19.2 in |
2 | Greyson Wenger | WI | Fond du Lac | 2025 | LHP | 18.3 in |
3 | Jackson Kobylarczyk | WI | Kettle Moraine Lutheran | 2025 | RHP | 17.9 in |
4 | Ian Butenhoff | WI | Wauwatosa West | 2026 | SS | 17.2 in |
5 | Lucky Pahl | WI | Winneconne | 2026 | RHP | 17.2 in |
6 | Kael Konrad | WI | Hortonville | 2025 | RHP | 16.8 in |
7 | Jackson Mayer | WI | Neenah | 2027 | LHP | 15.2 in |
8 | Andrew Wiesner | WI | Sevastopol | 2028 | RHP | 15.1 in |
9 | Dylan Campeau | WI | Greendale | 2025 | RHP | 15.0 in |
10 | Jack Adler | WI | Oconto Falls | 2025 | RHP | 14.6 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 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.”
