Hattiesburg Open: TrackMan Files
June 9, 2023
HATTIESBURG, MS - The Hattiesburg Open was held on Tuesday, June 6th at the The University of Southern Miss in Hattiesburg, 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 on Tuesday.
Kicking off our post-event coverage for this event, we take a look back at some of the top performers and standouts from Tuesday. 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.

Rank | Name | State | School | Class | Pos | Spin Rate (avg) |

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 | Jackson Meehan | MS | Northwest Rankin | 2026 | SS | 16.7 |
2 | Jett White | MS | Northwest Rankin | 2027 | OF | 16.0 |
3 | Nash McCrary | MS | Heritage Academy | 2026 | RHP | 15.9 |
4 | Micah Coutta | MS | South Jones | 2025 | LHP | -15.8 |
5 | Tre Adcox | MS | BRANDON HIGH SCHOOL | 2027 | 3B | 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.”
AVERAGE SLIDER SPIN RATE

4 | Micah Coutta | MS | South Jones | 2025 | LHP | 2073 |
5 | Dawson Dykes | MS | Petal High School | 2026 | OF | 1881 |
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

5 | Keith Forbes | MS | Brandon | 2025 | 3B | 1899 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 | Tre Adcox | MS | BRANDON HIGH SCHOOL | 2027 | 3B | 19.5 |
2 | Nash McCrary | MS | Heritage Academy | 2026 | RHP | 17.8 |

4 | Gavin Parrow | MS | MADISON CENTRAL HIGH SCHOOL | 2025 | SS | 15.8 |
5 | Keith Forbes | MS | Brandon | 2025 | 3B | 14.3 |
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.
