Marucci Elite Scout Day - TrackMan Files
September 27, 2021
On Sunday, September 19th, the PBR Texas staff hosted the Marucci Elite Scout Day at Baseball USA.
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 | Adam Troy | TX | Summer Creek | 2022 | RHP | 88.9 mph |
2 | Gavyn Jones | TX | White Oak | 2023 | LHP | 87.7 mph |
3 | Briley Van | TX | Barbers Hill | 2023 | RHP | 87.0 mph |
4 | Zyon Johnson | TX | Lamar Consolidated | 2022 | RHP | 86.5 mph |
5 | Peyton Brewer | TX | New Diana | 2023 | RHP | 86.1 mph |
Rank | Name | State | School | Class | Pos | Spin Rate (max) |
1 | Adam Troy | TX | Summer Creek | 2022 | RHP | 2302 rpm |
2 | Nicholas Partida | TX | Pearland | 2025 | SS | 2257 rpm |
3 | Keith Kennemer | TX | Crosby | 2023 | RHP | 2243 rpm |
4 | Gavyn Jones | TX | White Oak | 2023 | LHP | 2214 rpm |
5 | Briley Van | TX | Barbers Hill | 2023 | RHP | 2205 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 | Paolo Rappazzo | TX | Bellaire | 2025 | 3B | 13.5 |
2 | Peyton Brewer | TX | New Diana | 2023 | RHP | 13.3 |
3 | Briley Van | TX | Barbers Hill | 2023 | RHP | 13.3 |
4 | Joshua Kapp | TX | Katy Taylor | 2024 | SS | 13.2 |
5 | Andrew McArthur | TX | Crosby | 2025 | C | 13.1 |
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.”
