TN Fall Underclass Trials - TrackMan Files
October 28, 2021
On Sunday, October 24th, the PBR Tennessee scouting staff hosted the Fall Underclass Trials at Friendship Christian in Lebanon, TN. The event featured prospects from all high school classes from around the state.
Today, we’re continuing our post-event analysis by examining the data measured by our TrackMan units. The technology is able to capture information that’s difficult to capture by the naked eye, like pitch-by-pitch metrics and batted-ball data. We’ll explain more below:
MAX FASTBALL & PEAK SPIN RATE
Rank | Name | State | School | Class | Pos | Velocity (max) |
1 | Kole Gray | TN | Brentwood | 2024 | RHP | 86.2 mph |
2 | Quin Long | TN | Friendship Christian | 2024 | RHP | 85.1 mph |
3 | Collin Rittenberry | TN | Clarksville Academy | 2023 | RHP | 84.9 mph |
4 | Matt Dill | TN | The Baylor School | 2025 | 3B | 82.2 mph |
5 | Carter Casabella | TN | Station Camp | 2024 | RHP | 80.5 mph |
Rank | Name | State | School | Class | Pos | Spin Rate (max) |
1 | Quin Long | TN | Friendship Christian | 2024 | RHP | 2498 rpm |
2 | Kole Gray | TN | Brentwood | 2024 | RHP | 2392 rpm |
3 | Collin Rittenberry | TN | Clarksville Academy | 2023 | RHP | 2214 rpm |
4 | Brady Hendrix | TN | Summit | 2023 | SS | 2186 rpm |
5 | Matt Dill | TN | The Baylor School | 2025 | 3B | 2133 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 | Brady Hendrix | TN | Summit | 2023 | SS | 17.0 |
2 | Matt Dill | TN | The Baylor School | 2025 | 3B | 15.5 |
3 | Kirk Weatherford | TN | Clarksville High | 2025 | CF | 14.4 |
4 | Braden Woods | TN | Franklin | 2023 | RHP | 14.4 |
5 | Carter Casabella | TN | Station Camp | 2024 | RHP | 12.7 |
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 SLIDER SPIN RATE
AVERAGE CURVEBALL SPIN RATE
Rank | Name | State | School | Class | Pos | Spin Rate (avg) |
1 | Quin Long | TN | Friendship Christian | 2024 | RHP | 2562 rpm |
2 | Kole Gray | TN | Brentwood | 2024 | RHP | 2452 rpm |
3 | Dylan Woodard | TN | Goodpasture | 2024 | RHP | 2203 rpm |
4 | Kirk Weatherford | TN | Clarksville High | 2025 | CF | 2179 rpm |
5 | Collin Rittenberry | TN | Clarksville Academy | 2023 | RHP | 2098 rpm |
AVERAGE CHANGEUP HORIZONTAL MOVEMENT
Rank | Name | State | School | Class | Pos | HM (avg) |
1 | Matt Dill | TN | The Baylor School | 2025 | 3B | 20.5 |
2 | Brady Hendrix | TN | Summit | 2023 | SS | 17.1 |
3 | Carter Casabella | TN | Station Camp | 2024 | RHP | 16.1 |
4 | Kirk Weatherford | TN | Clarksville High | 2025 | CF | 14.3 |
5 | Jackson Moss | TN | Goodpasture | 2023 | OF | 13.3 |
AVERAGE EXIT VELOCITY (HITTING)
Rank | Name | State | School | Class | Pos | Exit Velocity (avg) |
1 | Caleb Moran | TN | Coffee County Central | 2023 | C | 94.8 mph |
2 | Jack Murray | TN | Sycamore | 2023 | C | 93.5 mph |
3 | Cullen Box | TN | Portland | 2023 | C | 88.2 mph |
4 | Mack Whitcomb | TN | Baylor | 2023 | C | 87.9 mph |

6 | Aidan Conley | TN | Montgomery Bell Academy | 2023 | SS | 84.6 mph |
7 | Kole Gray | TN | Brentwood | 2024 | RHP | 84.1 mph |
Exit Speed: Also according to TrackMan’s own website: “The speed of the ball, measured in miles per hour, as it comes off the bat at the moment of contact.”
