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:

TRACKMAN

FASTBALL

VELOCITY (MAX)

Rank Name State School Class Pos Velocity (max)
1 Nolan Buss WI Arrowhead 2024 RHP 93.0 mph
2 Garrett Shupe WI Mosinee 2024 RHP 89.2 mph
3 Bryce Loker WI Omro 2026 SS 84.9 mph
4 Jacob Riddick WI Ripon 2024 RHP 83.7 mph
5 James Mutchie WI Shiocton 2024 RHP 83.4 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 James Mutchie WI Shiocton 2024 RHP 2255 rpm
2 Nolan Buss WI Arrowhead 2024 RHP 2208 rpm
3 Ryan Apel WI Homestead 2025 3B 2201 rpm
4 Garrett Shupe WI Mosinee 2024 RHP 2197 rpm
5 Lawson Hink WI Brookfield Central 2024 RHP 2185 rpm
6 Sam Ernst WI Fond du Lac 2024 SS 2126 rpm
7 Bryce Loker WI Omro 2026 SS 2087 rpm
8 Zachary Kiffmeyer WI Oshkosh North 2025 RHP 2063 rpm
9 Aden Cherney WI Auburndale 2024 RHP 2055 rpm
10 Jacob Riddick WI Ripon 2024 RHP 2039 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 Jacob Riddick WI Ripon 2024 RHP 19.2 in
2 Ethan Edgar WI Pius XI 2024 RHP 18.9 in
3 Wade Spoerl WI Westosha Central 2025 OF 17.7 in
4 Bryce Loker WI Omro 2026 SS 17.3 in
5 Brady Bozich WI South Milwaukee 2024 LHP 16.6 in
6 Sam Ernst WI Fond du Lac 2024 SS 16.5 in
7 Dylan Fredrick WI Oconomowoc 2025 RHP 15.9 in
8 Lawson Hink WI Brookfield Central 2024 RHP 15.8 in
9 Nathan Miller WI Slinger 2026 RHP 15.2 in
10 Ryan Apel WI Homestead 2025 3B 14.9 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 Kolin Schiller WI West Bend East 2026 LHP -14.8
2 Ryan Apel WI Homestead 2025 3B 14.6
3 Nathan Miller WI Slinger 2026 RHP 14.1
4 Mason Foerstera WI Oconomowoc 2024 RHP 14.0
5 James Mutchie WI Shiocton 2024 RHP 13.3

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.”

STRIKE ZONE RATE%

Rank Name State School Class Pos Zone %
1 Dylan Fredrick WI Oconomowoc 2025 RHP 66 %
2 Michael Zink WI Janesville Craig 2024 RHP 62 %
3 Mason Foerstera WI Oconomowoc 2024 RHP 60 %

Average MLB pitchers throw 62% strikes, and better pitchers throw strikes 65% of the time, or roughly 2:1 strikes to balls.
