West Suburban Open: Pitching Data Dive
July 5, 2023
On Tuesday, June 27th the PBR Illinois team hosted the West Suburban Open at Lee Pfund Field in Carol Stream, IL. This open event was for all high school classes (2024-27), and gave our staff a chance to get a look at 30+ uncommitted prospects before the summer gets into full swing.
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.
Friday, we took a closer look at some of the immediate standouts who caught our attention with our Quick Hits and 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:

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: 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 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.”
