Las Vegas Fall ID: Pitching Data Dive
October 19, 2023
On Sunday, October 15th, the PBR Nevada staff hosted it's first open event of the fall season with the Las Vegas Fall ID hosted on the campus of UNLV at Earl E. Wilson Baseball Stadium. This event featured 30 players from the Las Vegas area in the 2024 - 2027 classes and allowed our staff an opportunity to get an in-depth look and analysis of the players in attendance.
Earlier this week, we broke down the top measurable data performers from the event with our Statistical Analysis. Now, we will take a further in-depth look at the top pitchers with the help of our tech partnerships, broken down by the categories down below:

FASTBALL
MAX VELOCITY (MPH)
Rank | Name | State | School | Class | Pos | Velocity (max) |
1 | Shawn Mack | NV | Liberty HS | 2026 | 1B | 86.7 mph |
2 | Gustavo Crawford | NV | Shadow Ridge HS | 2025 | RHP | 83.9 mph |
3 | Jackson Nelson | NV | Shadow Ridge HS | 2025 | RHP | 83.1 mph |
4 | Wyatt Sheehan | NV | Desert Oasis | 2024 | RHP | 83.0 mph |
5 | Gavin Flake | NV | Boulder City HS | 2025 | RHP | 82.8 mph |
Max Fastball Velocity: This metric calculates the speed of the pitch as it’s released from the pitcher’s hand.
SPIN RATE (AVG)
Rank | Name | State | School | Class | Pos | Spin Rate (avg) |
1 | Connor Long | NV | Basic Academy of Int'l Studies HS | 2027 | SS | 2328 rpm |
2 | Jackson Nelson | NV | Shadow Ridge HS | 2025 | RHP | 2244 rpm |
3 | Gavin Flake | NV | Boulder City HS | 2025 | RHP | 2168 rpm |
4 | Shawn Mack | NV | Liberty HS | 2026 | 1B | 2153 rpm |
5 | Hudson Inouye | NV | Coronado | 2026 | RHP | 2148 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.
INDUCED VERTICAL BREAK (AVG.)
Rank | Name | State | School | Class | Pos | IVB (avg) |
1 | Ayden Timko | NV | Southeast Career Technical Academy HS | 2025 | OF | 18.4 in |
2 | Jackson Nelson | NV | Shadow Ridge HS | 2025 | RHP | 17.9 in |
3 | Shawn Mack | NV | Liberty HS | 2026 | 1B | 16.8 in |
4 | Caden Figueroa | NV | Desert Oasis HS | 2025 | OF | 15.6 in |
5 | Samuel Ponce | NV | Cimarron Memorial | 2024 | 1B | 14.3 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.
HORIZONTAL MOVEMENT (AVG.)
Rank | Name | State | School | Class | Pos | HM (avg) |
1 | Alexander Reese | NV | Shadow Ridge HS | 2025 | 1B | -15.6 |
2 | Keimani Johnson | NV | Palo Verde | 2026 | OF | -14.2 |
3 | Hudson Inouye | NV | Coronado | 2026 | RHP | 12.4 |
4 | Gavin Flake | NV | Boulder City HS | 2025 | RHP | 9.9 |
5 | Connor Long | NV | Basic Academy of Int'l Studies HS | 2027 | SS | 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.”
