Milwaukee Open: Pitcher Data Dive


Josh Fields
Area Scout

On Tuesday, June 13th the PBR Wisconsin team hosted the Milwaukee Open at The Rock in Franklin, WI. 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.

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 Rocco Conrad WI New Berlin West 2025 RHP 86.8 mph
2 Sawyer Conradt SC P27 2025 RHP 85.1 mph
3 Paulson Yesbeck WI Elkhorn Area 2025 RHP 84.9 mph
4 Montgomery O'Brien WI Wauwatosa East 2026 LHP 80.1 mph
5 Ben Mills WI Oak Creek 2025 RHP 79.2 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 Wellentin WI Arrowhead 2025 RHP 2172 rpm
2 Paulson Yesbeck WI Elkhorn Area 2025 RHP 2093 rpm
3 Rocco Conrad WI New Berlin West 2025 RHP 2090 rpm
4 Ben Mills WI Oak Creek 2025 RHP 2074 rpm
5 Zaidan Eblin WI Waterford Union 2025 RHP 2059 rpm
6 Sawyer Conradt SC P27 2025 RHP 2042 rpm
7 Carson Young IL Antioch Comm High School 2025 RHP 2041 rpm
8 Montgomery O'Brien WI Wauwatosa East 2026 LHP 2017 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 Rocco Conrad WI New Berlin West 2025 RHP 18.5 in
2 Carson Young IL Antioch Comm High School 2025 RHP 15.0 in
3 Ben Mills WI Oak Creek 2025 RHP 14.0 in
4 Paulson Yesbeck WI Elkhorn Area 2025 RHP 12.1 in
5 Sawyer Conradt SC P27 2025 RHP 12.0 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 Jack Majerowski IL Antioch 2025 RHP 14.7
2 Owen Borkowski WI Oconomowoc 2024 LHP -14.3
3 Sawyer Conradt SC P27 2025 RHP 12.8
4 Montgomery O'Brien WI Wauwatosa East 2026 LHP -11.5
5 Carson Young IL Antioch Comm High School 2025 RHP 10.2

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 Rocco Conrad WI New Berlin West 2025 RHP 85 %
2 Montgomery O'Brien WI Wauwatosa East 2026 LHP 66 %
^ Zaidan Eblin WI Waterford Union 2025 RHP 66 %
3 Carson Young IL Antioch Comm High School 2025 RHP 60 %

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