On Sunday, Feb. 12, the PBR Illinois team hosted the O'Hare Preseason ID at Bo Jackson's Elite Sports in Bensenville, Ill. The event featured over 202 players and provided our staff with an in-depth look at some of the area's top prospects.

Yesterday, we broke down the top measurable data performers from the event with our Statistical Analysis.  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:

9	Mac McGarry	IL	Nazareth Academy	2025	RHP	84.3 mph
10	Christian McGrath	IL	St. Rita	2024	RHP	84.1 mph

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

1	Mac McGarry	IL	Nazareth Academy	2025	RHP	2299 rpm
2	Jack Wilson	IL	New Trier	2024	RHP	2273 rpm
3	Jackson Clark	IL	Hinsdale Central	2025	RHP	2237 rpm
4	Timothy McCormick	IL	lyons township	2025	LHP	2231 rpm
5	Kyle Wayda	IL	Jacobs	2025	RHP	2222 rpm
6	Max Lerner	IL	Glenbrook North	2025	RHP	2216 rpm
7	Andrew Kouris	IL	Nazareth Academy	2025	3B	2212 rpm
8	Joshua Wicker	IL	Fenwick	2024	2B	2186 rpm
9	Ryan Harris	IL	Stevenson	2026	OF	2179 rpm
10	Blake Heyer	IL	Montini Catholic	2026	RHP	2176 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.)

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.)

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.”
