Milwaukee Summer ID: Pitcher Data Dive
June 21, 2024
On June. 18th, The Prep Baseball Wisconsin staff hosted the first Summer ID of 2024: The Milwaukee 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.
Last week, we published our Quick Hits, and Statistical Analysis highlighting some of the top players from the event. Today, we will be looking at the top measurable data performers from the event, found below.

8 | Brady Schoenfeld | WI | Indian Trail | 2027 | SS | 2071 rpm |
9 | Evan Cichanofsky | WI | Bay Port | 2025 | LHP | 2071 rpm |
10 | Lucas Wirth | WI | Homestead High | 2025 | SS | 2068 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 | Evan Weckman | WI | St Thomas More | 2027 | OF | 23.8 in |
2 | Mason Grafwallner | WI | Greenfield | 2026 | 3B | 21.7 in |
3 | Coleton Cohen | WI | Nathan Hale | 2027 | SS | 20.9 in |
4 | Nick Stellrecht | WI | New Richmond | 2026 | RHP | 20.1 in |
5 | Oliver Ruedinger | WI | Mukwonago High | 2025 | LHP | 19.5 in |
6 | Lucas Weber | WI | Whitnall | 2027 | RHP | 19.3 in |
7 | Lucas Wirth | WI | Homestead High | 2025 | SS | 19.1 in |
8 | Paulson Yesbeck | WI | Elkhorn | 2025 | RHP | 18.1 in |
9 | Brayden Alivo | WI | St. Thomas More | 2026 | SS | 17.8 in |
10 | Carson Young | IL | Antioch | 2025 | RHP | 17.7 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.

10 | Evan Weckman | WI | St Thomas More | 2027 | OF | 11.4 |
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.”
