South Suburban Summer ID: Pitching Data Dive
June 14, 2024
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 | 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 | 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 High School | 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 | 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.”
