Preseason ProCase: Pitching Data Dive
February 2, 2024
On Jan. 31, the Prep Baseball Illinois staff hosted the Preseason ProCase at Rhino Sports Academy in Shorewood, Ill. This event featured 20 prospects, most of whom are Illinois natives and few from Wisconsin, and allowed our staff as well as the MLB scouts in attendance the opportunity to get an in-depth look at the players in attendance.
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. 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 | Aidan Hayse | IL | Joliet Catholic | 2024 | RHP | 93.9 mph |
2 | Bryce Koch | IL | Barrington | 2024 | RHP | 92.6 mph |
3 | Ethan Eberle | IL | Normal Community | 2024 | LHP | 92.2 mph |
4 | Jack Olson | IL | Antioch | 2024 | RHP | 91.9 mph |
5 | Blaine Williams | IL | Tremont | 2025 | C | 91.4 mph |
6 | Brayden Mazzacano | IL | Schaumburg | 2024 | OF | 91.1 mph |
7 | Luke Weber | IL | Highland Park | 2024 | RHP | 91.0 mph |
8 | Ryan Anderson | IL | Minooka | 2024 | RHP | 88.6 mph |
9 | David Cox | IL | Nazareth Academy | 2024 | SS | 88.4 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 | Bryce Koch | IL | Barrington | 2024 | RHP | 2475 rpm |
2 | Ryan Anderson | IL | Minooka | 2024 | RHP | 2251 rpm |
3 | Brayden Mazzacano | IL | Schaumburg | 2024 | OF | 2236 rpm |
4 | Jack Olson | IL | Antioch | 2024 | RHP | 2218 rpm |
5 | Aidan Hayse | IL | Joliet Catholic | 2024 | RHP | 2206 rpm |
6 | Blaine Williams | IL | Tremont | 2025 | C | 2120 rpm |
7 | David Cox | IL | Nazareth Academy | 2024 | SS | 2083 rpm |
8 | Ethan Eberle | IL | Normal Community | 2024 | LHP | 2005 rpm |
9 | Luke Weber | IL | Highland Park | 2024 | RHP | 1825 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 | Bryce Koch | IL | Barrington | 2024 | RHP | 19.1 in |
2 | Brayden Mazzacano | IL | Schaumburg | 2024 | OF | 16.0 in |
3 | Jack Olson | IL | Antioch | 2024 | RHP | 14.4 in |
4 | Blaine Williams | IL | Tremont | 2025 | C | 11.1 in |
5 | Aidan Hayse | IL | Joliet Catholic | 2024 | RHP | 11.0 in |
6 | Ethan Eberle | IL | Normal Community | 2024 | LHP | 9.0 in |
7 | Luke Weber | IL | Highland Park | 2024 | RHP | 8.3 in |
8 | David Cox | IL | Nazareth Academy | 2024 | SS | 7.9 in |
9 | Ryan Anderson | IL | Minooka | 2024 | RHP | 6.2 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 | David Cox | IL | Nazareth Academy | 2024 | SS | 17.3 |
2 | Ethan Eberle | IL | Normal Community | 2024 | LHP | -16.8 |
3 | Brayden Mazzacano | IL | Schaumburg | 2024 | OF | -13.0 |
4 | Jack Olson | IL | Antioch | 2024 | RHP | 12.8 |
5 | Luke Weber | IL | Highland Park | 2024 | RHP | 12.5 |
6 | Aidan Hayse | IL | Joliet Catholic | 2024 | RHP | 11.8 |
7 | Ryan Anderson | IL | Minooka | 2024 | RHP | 9.2 |
8 | Bryce Koch | IL | Barrington | 2024 | RHP | 4.5 |
9 | Blaine Williams | IL | Tremont | 2025 | C | 3.2 |
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.”
