Northwest Suburban Open: Pitching Data Dive


Kevin Cronin
Tech Analyst, Area Scout

On Tuesday, July 11, the PBR Illinois Staff hosted the Northwest Suburban Open at Wintrust Field in Schaumburg, IL. The event featured 60+ prospects and gave our scouting staff an quality look at players from all ranks of high school.

For a closer look at the showcase details and the technologies we'll have on-site to assist our in-person evaluation for all in attendance, click here. For a complete look at those registered to attend this event, view the most up-to-date version of the roster by clicking here.

Yesterday, we published our Statistical Analysis, where we broke down the stat leaders from the more traditional categories. 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:

TRACKMAN

FASTBALL

VELOCITY (MAX)

Rank Name State School Class Pos Velocity (max)
1 Braden Grimm IL Evanston 2024 RHP 87.6 mph
2 Peter Thompson IL Loyola Academy 2025 RHP 87.2 mph
3 Matthew Steinberg IL St. Charles East 2025 RHP 85.3 mph
4 Jackson Stahl IL Hononegah 2026 RHP 83.9 mph
5 Maddux Clarence IL DeKalb 2024 C 83.0 mph

Max Fastball Velocity: This metric calculates the speed of the pitch as it’s released from the pitcher’s hand.

SPIN RATE (AVG.)

Rank Name State School Class Pos Spin Rate (avg)
1 Braden Grimm IL Evanston 2024 RHP 2471 rpm
2 Peter Thompson IL Loyola Academy 2025 RHP 2379 rpm
3 Nathan Moline IL St. Charles East 2026 RHP 2369 rpm
4 Braden Mann IL Warren Township 2024 OF 2347 rpm
5 Maddux Clarence IL DeKalb 2024 C 2344 rpm
6 Jordan Shoemaker IL Metea Valley 2025 OF 2334 rpm
7 Zack Ziroli IL Downers Grove North 2025 LHP 2239 rpm
8 Jackson Stahl IL Hononegah 2026 RHP 2238 rpm
9 Sean Sherwood IL Prairie Ridge 2025 OF 2150 rpm
10 Simon Bromberek IL Lincoln-Way East 2024 RHP 2119 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 Maddux Clarence IL DeKalb 2024 C 18.8 in
2 Edgar Berge IL Maine East High School 2026 LHP 18.1 in
3 Bobby Pitula IL Lincoln-Way East High School 2027 RHP 17.7 in
4 Nathan Moline IL St. Charles East 2026 RHP 17.0 in
5 Peter Thompson IL Loyola Academy 2025 RHP 16.2 in
6 Christian Wolff WI Badger 2024 3B 15.5 in
7 Matthew Steinberg IL St. Charles East 2025 RHP 15.2 in
8 Aidan Nelson IL Notre Dame College Prep 2025 RHP 14.5 in
9 Sean Sherwood IL Prairie Ridge 2025 OF 14.4 in
10 Peyton Tucker WI Beloit Turner 2027 RHP 13.9 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 efficiency. 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 the vertical approach angle.

HORIZONTAL MOVEMENT (AVG.)

Rank Name State School Class Pos HM (avg)
1 Robby Stankus IL Bartlett 2024 RHP 20.1
2 Jackson Stahl IL Hononegah 2026 RHP 17.7
3 Christian Filas IL Grayslake North 2025 RHP 16.5
4 Zack Ziroli IL Downers Grove North 2025 LHP -15.9
5 Nathan Moline IL St. Charles East 2026 RHP 15.3

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%

Rank Name State School Class Pos Zone %
1 Zack Ziroli IL Downers Grove North 2025 LHP 83 %
2 Simon Bromberek IL Lincoln-Way East 2024 RHP 71 %
3 Nathan Moline IL St. Charles East 2026 RHP 66 %
^ Declan Spinner IL New Trier 2024 LHP 66 %
^ Christian Wolff WI Badger 2024 3B 66 %

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