South Suburban Summer ID: Pitching Data Dive


Kevin Cronin
Illinois & Wisconsin Data Coordinator, Area Scout

On Tuesday, June 11th, the Prep Baseball Illinois staff traveled to Ozinga Field in Crestwood, Illinois to host the South Suburban Summer ID. The event hosted 30 players from across the state and allowed our staff to get a closer look at these players to kick off the summer circuit.

Yesterday, we looked at the top measurable data performers from the event, found in our Statistical Analysis, where we broke down the stat leaders from the more traditional categories. We also released our Quick Hits from the event, highlighting some of the event's top prospects.

Now, 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 Jack Tamer IL Lincoln-Way East High School 2025 RHP 86.1 mph
2 Wade Ozment IL Crystal Lake Central 2027 OF 83.8 mph
3 Jonny Lee IL Romeoville 2025 SS 83.7 mph
4 Langston Booth IL Loyola Academy 2027 RHP 83.3 mph
5 Brody Kelsey IL Oswego 2025 LHP 82.0 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 Kevin Duggan IL St. Laurence 2027 RHP 2220 rpm
2 Jack Gordon IL Andrew 2026 RHP 2184 rpm
3 Wade Ozment IL Crystal Lake Central 2027 OF 2053 rpm
4 Isaac Stoelinga IL Young Magnet High School 2027 OF 1977 rpm
5 Daniel Bachler IL Mount Carmel 2027 SS 1974 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 Andrew Haraburda IL Montini Catholic 2028 RHP 17.7 in
2 Jack Tamer IL Lincoln-Way East High School 2025 RHP 16.6 in
3 James Iles IL Andrew 2026 OF 15.9 in
4 Jack Gordon IL Andrew 2026 RHP 15.8 in
5 Langston Booth IL Loyola Academy 2027 RHP 14.8 in
6 Jonny Lee IL Romeoville 2025 SS 14.8 in
7 Bralen Mitcham IL Lincoln-Way East 2025 RHP 14.2 in
8 Kevin Duggan IL St. Laurence 2027 RHP 14.1 in
9 Steven Gonzalez Jr IL St. Rita 2025 RHP 13.5 in
10 James Jefferson IL Parkview Christian Academy 2026 C 13.0 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 Wade Ozment IL Crystal Lake Central 2027 OF 19.5
2 Andrew Haraburda IL Montini Catholic 2028 RHP 18.8
3 Charlie Caroselli IL PROVIDENCE CATHOLIC CHILDRENS ACADEMY 2027 RHP 15.7
4 Cristo Fernandez IL Argo Community High School 2025 OF 15.4
5 Matthew Rashan IL Chicago Christian 2025 RHP 13.3
6 Jack Gordon IL Andrew 2026 RHP 13.2
7 Brody Kelsey IL Oswego 2025 LHP -12.1
8 Kevin Duggan IL St. Laurence 2027 RHP 11.7
9 Daniel Bachler IL Mount Carmel 2027 SS 10.9
10 Jonny Lee IL Romeoville 2025 SS 10.8

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 Maddux Chiquito IL Joliet West 2026 3B 100 %

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