Underclass Open: TrackMan Files

On June 22, the PBR Wisconsin staff kicked off the summer tour with the Underclass Open, held at The Rock Sports Complex in Franklin, Wis. It routinely provides us an opportunity to check see prospects prior to the summer circuit kicking off, and this year’s event featured players from the 2024-2026 grad classes.

Last week we published Quick Hits highlighting the top prospects of the event by class. We also rolled out a Statistical Analysis pointing out the top recorded stats by category.

 Now we'll continue to roll out the data we gathered from this event, starting with the analytics we have at our disposal from our TrackMan units. Below we'll look at which players had noteworthy batted ball and pitch metric data.

9 Brock Goral WI Waukesha West 2025 OF 1976 rpm
10 Sawyer Conradt SC P27 2025 RHP 1960 rpm

Max Fastball Velocity: This metric calculates the speed of the pitch as it’s released from the pitcher’s hand.

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.

AVERAGE FASTBALL HORIZONTAL MOVEMENT

Rank Name State School Class Pos HM (avg)
1 Peyton Lenell WI Brookfield Central 2026 SS 20.3
2 Owen Borkowski WI Oconomowoc 2024 LHP -19.2
3 Ethan Meves WI Union Grove 2025 LHP -18.1
4 Kody Hage WI Union Grove 2025 3B 15.9
5 Parker Bleck WI Xavier 2024 RHP 14.9
6 Treyton Schumacher WI Culver Academy 2025 OF -14.7
7 Charlie Wahlen WI Dominican 2024 3B 13.3
8 Benjamin Wellentin WI Arrowhead 2025 RHP 12.8
9 Cashton Jones WI Madison Memorial 2024 RHP 12.1
10 Sawyer Conradt SC P27 2025 RHP 12.0

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.”
