Top Prospect Games: Underclass - Data Dive, Pitchers
June 12, 2023
On June 6th, we hosted Class of 2025-2027 grads at the Top Prospect Games: Underclass. This event featured over 100 prospects from Georgia, and it provided our staff with an in-depth look at some high-follow players into the summer and next spring.
Inside today’s Pitching Data dive we will highlight the players with top metrics per Trackman.
Last week, we broke down the stat leaders from the more traditional categories in our statistical analysis. Today, we will take an even closer look at the pitchers in attendance with the help of our tech partners, broken down by the categories and leaderboards below.

10 | Aiden Zagryn | GA | BLESSED TRINITY CATHOLIC HIGH SCHOOL | 2025 | 3B | 2099 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.
SPIN EFFICIENCY% (AVG.)
Rank | Name | State | School | Class | Pos | Spin Efficiency % (avg) |
1 | Gabe Gowder | GA | Cherokee Bluff | 2025 | LHP | 99 % |
2 | Clayton Hicks | GA | Evans | 2025 | RHP | 97 % |
3 | Michael Hunter Stonecipher | GA | East Cobb Baseball Academy | 2025 | C | 97 % |
4 | Martin Shelar | GA | Marist | 2026 | OF | 96 % |
5 | Reece Grodeman | GA | Model High | 2026 | RHP | 96 % |
6 | Campbell Payton | GA | North Hall | 2025 | LHP | 95 % |
7 | Will Colvin | GA | Lakeside | 2026 | C | 94 % |
8 | Brock Holcombe | GA | Lakeside | 2027 | OF | 94 % |
9 | Brayden Weems | GA | North Forsyth | 2025 | LHP | 93 % |
10 | Carson Bruce | GA | North Cobb Christian | 2027 | 1B | 93 % |
Spin Efficiency: This metric is the percentage of the raw spin rate that directly impacts pitch movement; so while raw spin is measured by revolutions per minute (rpm), spin efficiency is the ratio of true spin divided by raw spin. It’s important to understand that more is not always better when it comes to spin efficiency. The optimal spin efficiency on a pitch depends on the pitch type and should be understood in the context of a pitcher’s entire arsenal. Regarding the true four-seam fastball, a spin efficiency close to 100 percent is preferable, indicating that nearly all the backspin generated on the ball as it leaves the pitcher’s hand is contributing to the “riding” action the pitch has as it enters and exits the strike zone, making it especially effective in the upper third of the strike zone.
INDUCED VERTICAL BREAK (AVG.)
Rank | Name | State | School | Class | Pos | IVB (avg) |
1 | Todd Haley | GA | Walton | 2026 | 1B | 20.2 in |
2 | Jackson Sammons | GA | SAVANNAH COUNTRY DAY SCHOOL | 2025 | RHP | 19.4 in |
3 | Gabe Gowder | GA | Cherokee Bluff | 2025 | LHP | 18.6 in |
4 | Michael Hunter Stonecipher | GA | East Cobb Baseball Academy | 2025 | C | 18.4 in |
5 | Martin Shelar | GA | Marist | 2026 | OF | 18.1 in |
6 | Brady Holbrook | GA | North Forsyth | 2025 | LHP | 18.0 in |
7 | Will Colvin | GA | Lakeside | 2026 | C | 16.5 in |
8 | Oakley Willingham | GA | Peach County | 2025 | C | 16.5 in |
9 | Turk Williams | GA | North Paulding | 2026 | RHP | 16.4 in |
10 | Carson Bruce | GA | North Cobb Christian | 2027 | 1B | 16.1 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.

10 | Jude Matthews | GA | Lakeside High School | 2026 | LHP | -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.”
