South Mississippi Fall ID: TrackMan Files
September 27, 2023
POPLARVILLE, MS - The South Mississippi Fall ID was held on Saturday, September 23rd at Pearl River CC in Poplarville, MS. This event was an open event that consisted of some of the top prospects from the 2024-2027 classes across all parts of Mississippi. These players went through extended pro-style workout that included batting practice using Trackman, ran the 60 yard dash using Swift Performance, and much more. Pitchers were able to throw in simulated bullpens during the workout and were able to get numbers and metrics. There were some players who showed up and continued to build off of prior performances, but there were also some new names who jumped onto our radar with a strong showing at the event.
Continuing our post-event coverage for this event, we take a look back at some of the top performers and standouts from Saturday. Continuing over the course of the next week or so, we will release different statistical leaderboards for the event along with other pieces of content.

MAX FASTBALL & AVERAGE SPIN RATE

2 | Addison Jayroe | MS | Madison Central | 2025 | RHP | 83.1 mph |

Rank | Name | State | School | Class | Pos | Spin Rate (avg) |
1 | Cooper Hooks | MS | BRANDON HIGH SCHOOL | 2026 | RHP | 2223 rpm |
2 | Payton Smith | MS | GEORGE COUNTY HIGH SCHOOL | 2027 | RHP | 2098 rpm |
3 | Addison Jayroe | MS | Madison Central | 2025 | RHP | 2094 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 | Addison Jayroe | MS | Madison Central | 2025 | RHP | 15.9 |
2 | Cooper Hooks | MS | BRANDON HIGH SCHOOL | 2026 | RHP | 10.1 |
3 | Tinnin Potts | MS | CLINTON HIGH SCHOOL | 2025 | 3B | 9.8 |
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
Rank | Name | State | School | Class | Pos | Spin Rate (avg) |
1 | Payton Smith | MS | GEORGE COUNTY HIGH SCHOOL | 2027 | RHP | 2150 |
2 | Kellen Garcia | MS | SUMRALL HIGH SCHOOL | 2025 | SS | 1980 |
Spin Rate: The metric calculates how fast the ball is spinning as it leaves the pitcher’s hand, reported in the number of times the pitched ball would spin per minute (“revolutions per minute” or “rpm”).
AVERAGE CURVEBALL SPIN RATE
Rank | Name | State | School | Class | Pos | Spin Rate (avg) |
1 | Cooper Hooks | MS | BRANDON HIGH SCHOOL | 2026 | RHP | 2538 rpm |
2 | Addison Jayroe | MS | Madison Central | 2025 | RHP | 2193 rpm |
3 | Payton Smith | MS | GEORGE COUNTY HIGH SCHOOL | 2027 | RHP | 2060 rpm |
Spin Rate: The metric calculates how fast the ball is spinning as it leaves the pitcher’s hand, reported in the number of times the pitched ball would spin per minute (“revolutions per minute” or “rpm”).
AVERAGE CHANGEUP HORIZONTAL MOVEMENT
Rank | Name | State | School | Class | Pos | HM (avg) |
1 | Kellen Garcia | MS | SUMRALL HIGH SCHOOL | 2025 | SS | 15.9 |
2 | Cooper Hooks | MS | BRANDON HIGH SCHOOL | 2026 | RHP | 13.0 |
3 | Addison Jayroe | MS | Madison Central | 2025 | RHP | 12.9 |
Horizontal Break: This metric measures the distance, 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.
PEAK EXIT VELOCITY (HITTING)

1 | Tinnin Potts | MS | CLINTON HIGH SCHOOL | 2025 | 3B | 97.0 mph |
2 | Nicholas Arnold | MS | Madison Ridgeland Academy | 2024 | OF | 96.0 mph |
3 | Dalton Stripling | MS | New Hope | 2025 | SS | 94.2 mph |
4 | Stephen Hutchison | MS | Saint Stanislaus | 2025 | 3B | 93.3 mph |
5 | Mason Ruble | MS | Picayune Memorial | 2025 | 1B | 93.1 mph |
Exit Velocity: This metric measures the speed of the ball, measured in miles per hour, as it comes off the bat at the moment of contact.
PEAK ESTIMATED BATTED DISTANCE (HITTING)
Rank | Name | State | School | Class | Pos | Distance (max) |
1 | Justin San Miguel | MS | OCEAN SPRINGS HIGH SCHOOL | 2026 | SS | 354 ft |

4 | Nelson Barthel | MS | Northwest Rankin | 2026 | C | 335 ft |
5 | Dalton Stripling | MS | New Hope | 2025 | SS | 334 ft |
Distance: This metric measures the estimated “carry flat” distance, measured in feet, meaning the distance that the ball travels before it lands, or would have landed if it were not caught or obstructed.
