Las Vegas Summer ID: Pitching Data Dive

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.”
