Las Vegas Summer ID: Pitching Data Dive
August 11, 2024
On Wednesday, August 7th, the Prep Baseball Nevada staff hosted it's third event of the summer with the Las Vegas Summer ID at the College of Southern Nevada in Henderson, Nevada. This event featured roughly 22 players from the Las Vegas area in the 2025 - 2028 classes with all players running through a full workout alongside our tech partners TrackMan, Blast Motion and Swift Performance.
Summer ID's give players a chance to showcase their skills infront of our scouting staff before returning to school for the fall, as well as update their profiles with increased metrics as college recruiting continues to ramp up.
Yesterday we began our post-event coverage within our Statistical Analysis articles. 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 | Nicholas Collingbourne | NV | Southeast Career Tech | 2026 | RHP | 85.6 mph |
2 | Payton Bryan | NV | Shadow Ridge | 2026 | RHP | 84.1 mph |
3 | Jet McNelis | NV | Green Valley | 2026 | OF | 81.6 mph |
4 | Tiernon Wolf | NV | Southeast Career Tech | 2025 | 2B | 80.8 mph |
5 | Ryland Gregorich | NV | Clark | 2028 | SS | 77.7 mph |
6 | Dylan Blinn | NV | Bishop Gorman | 2026 | OF | 77.4 mph |
7 | Jacob Freitas | NV | Bishop Gorman | 2025 | LHP | 77.4 mph |
8 | Dylan Galvin | NV | Liberty | 2028 | SS | 75.8 mph |
9 | Parker Janssen | NV | Coronado HS | 2027 | LHP | 75.7 mph |
10 | Cocoro Tomonari | NV | Coronado | 2025 | RHP | 73.9 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 | Dylan Blinn | NV | Bishop Gorman | 2026 | OF | 2214 rpm |
2 | Ryland Gregorich | NV | Clark | 2028 | SS | 2142 rpm |
3 | Nicholas Collingbourne | NV | Southeast Career Tech | 2026 | RHP | 1953 rpm |
4 | Jet McNelis | NV | Green Valley | 2026 | OF | 1916 rpm |
5 | Payton Bryan | NV | Shadow Ridge | 2026 | RHP | 1893 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 | Dylan Galvin | NV | Liberty | 2028 | SS | 17.3 in |
2 | Payton Bryan | NV | Shadow Ridge | 2026 | RHP | 14.7 in |
3 | Dylan Blinn | NV | Bishop Gorman | 2026 | OF | 14.4 in |
4 | Cocoro Tomonari | NV | Coronado | 2025 | RHP | 14.0 in |
5 | Ryland Gregorich | NV | Clark | 2028 | SS | 13.7 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 | Jet McNelis | NV | Green Valley | 2026 | OF | 15.8 |
2 | Cocoro Tomonari | NV | Coronado | 2025 | RHP | 14.1 |
3 | Payton Bryan | NV | Shadow Ridge | 2026 | RHP | 13.8 |
4 | Ryland Gregorich | NV | Clark | 2028 | SS | 13.7 |
5 | Tiernon Wolf | NV | Southeast Career Tech | 2025 | 2B | 12.9 |
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.”
