On Tuesday, June 27th, the PBR Wisconsin team hosted the Madison Open at Sun Prairie East High School in Sun Prairie, WI. This open event was for all high school classes (2024-27), and gave our staff a chance to get a look at 20+ 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.

Thursday, we published our Quick Hits. Today, we published 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	Luke Hurlebaus	WI	Waunakee	2025	RHP	82.4 mph
2	Benjamin Ketelsen	WI	Sun Prairie West	2024	RHP	82.4 mph
3	Bennett O'Connor	WI	Middleton	2025	RHP	80.3 mph
4	Aidan Kammer	WI	Jefferson	2024	2B	79.0 mph
5	Bentley Wagner	WI	Jefferson High	2026	SS	78.6 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	Benjamin Ketelsen	WI	Sun Prairie West	2024	RHP	2434 rpm
2	Luke Hurlebaus	WI	Waunakee	2025	RHP	2245 rpm
3	Jackson Guerrero	WI	Middleton	2026	SS	2092 rpm
4	Aiden Rodriguez	WI	Middelton	2026	OF	1980 rpm
5	Bentley Wagner	WI	Jefferson High	2026	SS	1972 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.”

STRIKE ZONE RATE%

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