Green Bay Preseason ID: Pitcher Data Dive


Josh Fields
Wisconsin Staff

Feb 25, the PBR Wisconsin staff hosted the Green Bay Preseason ID, at Impact Sports Academy in De Pere, WI. This event featured around 120 prospects, most of whom are Wisconsin natives, and allowed our staff an opportunity to get an in-depth look at the players in attendance.

Wednesday, we published our Quick Hits from the event. Thursday, we broke down the top measurable data performers from the event with our Statistical Analysis. 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:

1 Tavian Ramos WI Neenah 2024 RHP 91.1 mph
2 Avery Duncan WI Notre Dame De La Baie Academy 2024 RHP 89.9 mph
3 Brady Koester WI Kimberly 2024 LHP 89.1 mph
4 Brennen Grams WI Kimberly 2024 RHP 88.2 mph
5 Loren Georger WI Appleton West 2025 RHP 87.0 mph
6 Easton Arendt WI De Pere 2024 OF 86.7 mph
7 Parker Bleck WI Xavier 2024 RHP 86.5 mph
8 Matthew Hietpas WI Appleton North 2026 OF 86.4 mph
9 Ethan Plog WI Bay Port 2024 LHP 86.0 mph
10 Drew Van Oss WI West De Pere 2024 OF 85.3 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 Tavian Ramos WI Neenah 2024 RHP 2391 rpm
2 Drew Van Oss WI West De Pere 2024 OF 2309 rpm
3 Brady Koester WI Kimberly 2024 LHP 2259 rpm
4 Loren Georger WI Appleton West 2025 RHP 2226 rpm
5 Carson Hawley WI Bay Port 2026 OF 2220 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 Jack Frelich WI Notre Dame Academy 2025 OF 19.9 in
2 Carson Hawley WI Bay Port 2026 OF 18.7 in
3 Nolan Sand WI Mishicot 2025 SS 18.4 in
4 Ian Aoki WI Ashwaubenon 2025 RHP 17.9 in
5 Colin Reddy WI Appleton North 2026 RHP 17.1 in
6 Teagan Anderson WI St. Thomas Aquinas 2025 SS 17.1 in
7 Gavin Lettenberger WI Manitowoc Lincoln 2024 1B 16.8 in
8 Isaac Verbruggen WI Neenah 2024 RHP 16.6 in
9 Drew Van Oss WI West De Pere 2024 OF 16.4 in
10 Andrew Lindsley WI Preble 2026 LHP 16.4 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 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.

HORIZONTAL MOVEMENT (AVG.)

Rank Name State School Class Pos HM (avg)
1 Brogan Wasurick WI Mishicot 2026 RHP 18.2
2 Carson Glosny WI Notre Dame Academy 2024 OF 17.5
3 Parker Bleck WI Xavier 2024 RHP 17.4
4 Bryson Koehne WI Notre Dame De La Baie Academy 2024 1B 16.8
5 Isaac Verbruggen WI Neenah 2024 RHP 15.8
6 Bron Schaefer WI Kaukauna 2026 LHP -15.4
7 Teagan Anderson WI St. Thomas Aquinas 2025 SS 15.1
8 Drew Van Oss WI West De Pere 2024 OF 14.7
9 Connor Amsler WI Neenah 2026 RHP 14.5
10 Matthew Hietpas WI Appleton North 2026 OF 14.3

 

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.”
