Top Prospect Games Underclass: TrackMan Files


By: Diego Solares
Area Scout, Illinois & Missouri

On Tuesday, June 7, the PBR Missouri staff traveled to Atkins Field in Columbia, MO, to host the Top Prospect Games: Underclass event. Formerly touted as the MO Underclass Games, this invite-only event featured more than 60 names representing the 2024-to-2026 grad classes across the entire ‘Show Me’ state. Those in attendance will participate in a pro-style workout to begin the event, followed by live game action.

Yesterday we rolled out the Stat Story from this event, highlighting which players found themselves atop the leaderboards from this event. Today, with the help of our tech partners, we'll dive deeper into the numbers collected by analyzing the pitch metrics and batted ball data captured throughout the day.

Read below to see which prospects' popped from a data standpoint on our TrackMan units.

1 Tyler Holman MO Liberty 2024 RHP 2487 rpm
2 Jordan Martin MO Jefferson City 2025 SS 2466 rpm
3 Mason Lee MO Pattonville 2025 1B 2337 rpm

5 Carter Cox MO Fort Zumwalt South 2024 LHP 2286 rpm
6 Brandon McQuerrey MO Wentzville North Point 2024 RHP 2273 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 Landon Matthews MO Lafayette 2026 OF 18.1
2 Alex Korte MO Christian Brothers College 2024 RHP 18.0
3 Derek Rockett MO Higbee 2024 SS 15.6
4 Harrison Lear MO Blair Oaks 2024 RHP 15.2
5 Jackson Heimann MO St. John Vianney 2024 OF 14.9

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.”
