Aurora Preseason ID: TrackMan Files


Kevin Cronin
Tech Analyst, Area Scout

On Feb. 5, the PBR Illinois team hosted the Aurora Preseason ID at the Sport Zone in Aurora, Ill. This open event featured players from the 2022-25 high school grad classes, providing our staff with an ample opportunity to learn more about the area’s baseball talent. 

Earlier this 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.

MAX FASTBALL & PEAK SPIN RATE

Rank Name State School Class Pos Velocity (max)
1 Michael Belbot IL Stevenson 2023 RHP 88.8 mph
2 Luke Brown IL Plainfield North 2023 LHP 87.3 mph
3 Dominic Voegele IL Columbia 2023 RHP 87.3 mph
4 Cole Kratzberg IL Orion 2023 OF 84.6 mph

Rank Name State School Class Pos Spin Rate (max)
1 Luke Brown IL Plainfield North 2023 LHP 2483 rpm
2 Cole Kratzberg IL Orion 2023 OF 2398 rpm
3 Michael Belbot IL Stevenson 2023 RHP 2349 rpm
4 Luke Goss IL Pekin 2024 RHP 2242 rpm
5 Dominic Stringham IL Oswego 2024 SS 2229 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 Sam Rohlfing IL Harvest Christian Academy 2023 3B 17.5
2 Keller Westman IL Highland Park 2024 RHP 15.6
3 Thomas Walla IL St. Edward 2023 2B 15.3
4 Jackson Kottmeyer IL Kaneland 2024 RHP 14.7
5 Eric Strom IL Morris 2021 SS 14.4
6 Cole Harris IL Providence Catholic 2025 RHP 14.2
7 Antonio Villanueva IL Kaneland 2025 OF -14.1

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.”
