Western Wisconsin Summer ID: Pitcher Data Dive

July 17, 2025
By: Michael Anderson
Wisconsin Staff

On Tuesday, July 15th, the PB Wisconsin staff traveled to Valley Sports Academy in Lake Hallie, WI, to host the Western Wisconsin Summer ID, an open event for the class of 2026-2029.

Players made their way to Valley Sports Academy this past Tuesday and 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 Baseball Wisconsin staff.

Today, we will be looking at the top measurable data performers from the event, found below.

SPIN RATE (AVG.)

Rank Name State School Class Pos Spin Rate (avg)
1 Heath Rosemeyer WI Fall Creek 2029 RHP 2244 rpm
2 Wyatt Wolberg WI Iola-Scandinavia 2028 RHP 2094 rpm
3 Ryan DuMond WI River Falls 2027 RHP 2056 rpm
4 Carson Campbell WI Onalaska High School 2026 LHP 1989 rpm
5 Trace Marino WI Hayward 2027 LHP 1977 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 Carson Campbell WI Onalaska High School 2026 LHP 18.3 in
2 Ryan DuMond WI River Falls 2027 RHP 16.5 in
3 Trace Marino WI Hayward 2027 LHP 16.0 in
4 Evan Howard WI Johnson Creek 2029 2B 15.9 in
5 Ethan Westrate WI Fall Creek 2027 RHP 15.3 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 Wyatt Wolberg WI Iola-Scandinavia 2028 RHP 17.2
2 Carson Campbell WI Onalaska High School 2026 LHP -9.7
3 Evan Howard WI Johnson Creek 2029 2B 9.6
4 Ethan Westrate WI Fall Creek 2027 RHP 8.7
5 Heath Rosemeyer WI Fall Creek 2029 RHP 6.6

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 Trace Marino WI Hayward 2027 LHP 85 %
2 Carson Campbell WI Onalaska High School 2026 LHP 83 %
^ Ethan Westrate WI Fall Creek 2027 RHP 83 %

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