Fall Underclass Trials: TrackMan Pitching Analysis


Phil Kerber
Georgia Scouting Director



This summer, Prep Baseball Report events across the country have been powered by TrackMan’s industry-leading Portable system to capture pinpoint accurate, actionable data from player performances. Prep Baseball Report and TrackMan are dedicated to recognizing talent and unleashing their potential.


At the Fall Underclass Trials, when pitchers took the mound, every pitch was logged via TrackMan Portable units. Key metrics were collected on many of the top uncommitted players in the country. Today, we share leaderboards of velocity, spin rates, extension and movement.

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 Extension (Fastball)

Rank Name State School Class Pos Extension (avg)
1 Quindon Wright GA Terrell Acadamy 2024 OF 6.4 ft
2 JoJo Martin GA Jefferson 2023 OF 6.2 ft
3 Alex Karst GA Campbell 2023 1B 6.0 ft
4 Heath Whitlock GA Starr's Mill 2024 OF 5.9 ft
5 Evan Doss GA East Coweta 2024 C 5.7 ft
6 Trevor Booton GA LaGrange 2023 RHP 5.7 ft
7 Evan O'Neill GA Blessed Trinity 2023 RHP 5.6 ft
8 Isaiah Haygood GA Valdosta 2024 LHP 5.6 ft
9 Gant Geiger GA Charlton County 2023 RHP 5.5 ft
10 Ellington Hodge GA Decatur 2024 SS 5.5 ft

Extension: The measurement of the release point relative to the rubber, reported in feet. Essentially, a higher extension can create an advantage for pitchers as they shorten the time in which the ball is traveling from their hand to home.

Average Fastball Horizontal Movement

Rank Name State School Class Pos HM (avg)
1 Isaiah Haygood GA Valdosta 2024 LHP 15.3
2 Landon Lee GA North Hall 2023 RHP -13.7
3 Caden Henderson GA Ware County 2023 3B -11.1
4 Heath Whitlock GA Starr's Mill 2024 OF 10.7
5 Davis Budd GA North Paulding 2023 RHP -9.3
6 Nate Isler GA Cambridge 2023 RHP -8.1
7 Evan Doss GA East Coweta 2024 C -8.0
8 Aaron Peterson GA Mount Pisgah Christian 2024 1B -7.9
9 Kade Nicholson GA Habersham Central 2024 RHP -7.7
10 Braxton Yerta AL Chambers Academy 2023 SS -7.0

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.”

Average Fastball Induced Vertical Movement

Rank Name State School Class Pos IVB (avg)
1 KJ Moon GA North Oconee 2024 RHP 22.7 in
2 Reid Harvey GA Thomas County Central 2023 3B 20.4 in
3 Braxton Yerta AL Chambers Academy 2023 SS 20.1 in
4 Evan O'Neill GA Blessed Trinity 2023 RHP 19.0 in
5 Davis Budd GA North Paulding 2023 RHP 19.0 in
6 JoJo Martin GA Jefferson 2023 OF 18.8 in
7 Gant Geiger GA Charlton County 2023 RHP 18.6 in
8 Will Walker GA Seminole Couty 2023 SS 18.1 in
9 Landon Lee GA North Hall 2023 RHP 17.3 in
10 Quindon Wright GA Terrell Acadamy 2024 OF 16.8 in

Induced Vertical Break: Outline on TrackMan's own website: "... Distance, measured in inches, between where the pitch actually crosses the front of home plate height-wise, and where it would have crossed home plate height-wise if had it traveled in a perfectly straight line from release, but affected by gravity. If this number is positive, the ball broke “upwards”, or in reality dropped less than it would have due to gravity alone – it does not necessarily mean that the ball actually rose.
