Upperclass Top Prospect Games: Pitching Data Dive
June 7, 2024
This past Monday and Tuesday, the Prep Baseball Arizona staff continued it's Summer Tour as we hosted our marquee event of the summer for upperclassman with the Upperclass Top Prospect Games at Grand Canyon University in Phoenix, Arizona. This event featured roughly 71 prospects from the 2025 and 2026 classes and featured a large crop of Arizona's top uncommitted incoming seniors and juniors, as well as a couple committed players who also impressed.
The event allowed our staff to collect updated data on all athletes, as well as give us an up-close look at the players ahead of the high school season and our updated rankings that will be rolling out.
Earlier this week, we broke down the top measurable data performers from the event with our Statistical Analysis article. 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 | Ryan Jung | AZ | Pinnacle High School | 2025 | RHP | 91.6 mph |
2 | Devin Long | AZ | Chaparral High School | 2026 | RHP | 91.1 mph |
3 | Diesel Toth | CA | ARROWHEAD CHRISTIAN ACADEMY | 2025 | SS | 90.9 mph |
4 | Brody James | AZ | Desert Mountain High School | 2026 | RHP | 88.4 mph |
5 | Brock MacDonald | AZ | Desert Vista High School | 2026 | RHP | 88.1 mph |
6 | Landon Hood | AZ | Canyon View | 2025 | RHP | 87.8 mph |
7 | Henry Verhamme | AZ | Cactus Shadows High School | 2026 | SS | 87.5 mph |
8 | Roman Carrington | AZ | Homeschool (AZ) | 2026 | SS | 87.3 mph |
9 | Devin Morganfield | AZ | VALLEY CHRISTIAN SCHOOLS | 2026 | RHP | 87.3 mph |
10 | Jack Scully | AZ | Cactus Shadows High School | 2026 | 3B | 87.1 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 | Jace Terry | AZ | NOTRE DAME PREPARATORY | 2025 | SS | 2485 rpm |
2 | Jack Scully | AZ | Cactus Shadows High School | 2026 | 3B | 2410 rpm |
3 | Landon Hood | AZ | Canyon View | 2025 | RHP | 2259 rpm |
4 | Zachary Durben | AZ | Desert Mountain | 2026 | SS | 2259 rpm |
5 | Thomas Pascanu | AZ | Sandra Day O'Connor | 2026 | LHP | 2254 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 | Logan Gutterman | AZ | Highland High School | 2025 | LHP | 20.3 in |
2 | Kanon Faseler | AZ | Horizon High School | 2026 | OF | 17.0 in |
3 | Zachary Durben | AZ | Desert Mountain | 2026 | SS | 16.6 in |
4 | Thomas Pascanu | AZ | Sandra Day O'Connor | 2026 | LHP | 16.5 in |
5 | Roman Carrington | AZ | Homeschool (AZ) | 2026 | SS | 16.4 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 | Ryan Fesperman | AZ | BROPHY COLLEGE PREPARATORY | 2026 | 1B | -13.0 |
2 | Owen Konerko | AZ | Cactus Shadows High School | 2027 | 3B | 13.0 |
3 | Ryan Jung | AZ | Pinnacle High School | 2025 | RHP | 11.6 |
4 | Jace Terry | AZ | NOTRE DAME PREPARATORY | 2025 | SS | 11.4 |
5 | Devin Morganfield | AZ | VALLEY CHRISTIAN SCHOOLS | 2026 | RHP | 11.3 |
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.”
