Green Bay Preseason ID: Pitcher Data Dive


By. Josh Fields
Area Scout, Data Coordinator

On Feb. 24th, the Prep Baseball Wisconsin staff hosted the Green Bay Preseason ID at Impact Sports Academy in De Pere, WI. Over 100 players participated in a pro-style workout, gathering unrivaled access to data through our state-of-the-art tech partners, as well as in-depth scouting analysis from our Prep Baseball Wisconsin staff.

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 positional prospects with the help from our tech partnerships, broken down by the categories down below:

9 Griffin Jens WI Hortonville 2025 RHP 2193 rpm
10 Ben Hites WI Greendale 2025 RHP 2185 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: 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 efficiencies. 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 vertical approach angle.

9 Liam OToole WI Plymouth 2027 RHP 15.1
10 Isaac Aoki WI Ashwaubenon 2027 OF 15.1

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.”
