Tucson Fall ID: Pitching Data Dive
October 4, 2023
On Sunday, October 1st, the PBR Arizona staff hosted the Tucson Fall ID at Hi Corbett Field, home of the University of Arizona Wildcats baseball program in Tucson, Arizona. This event featured 21 uncommitted prospects from the 2024 - 2027 classes and allowed our staff an opportunity to get an in-depth look at the players in attendance.
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 | Michel Muniz Jr | AZ | Sunnyside | 2025 | C | 86.0 mph |
2 | Henry Verhamme | AZ | Cactus Shadows High School | 2026 | SS | 83.4 mph |
3 | Denzel Montijo | AZ | Nogales | 2025 | 3B | 83.3 mph |
4 | Rafael Echeverria | AZ | Rio Rico | 2025 | LHP | 80.9 mph |
5 | Brayden Hoyler | AZ | Canyon Del Oro High School | 2027 | SS | 79.7 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 | Rafael Echeverria | AZ | Rio Rico | 2025 | LHP | 2265 rpm |
2 | Michel Muniz Jr | AZ | Sunnyside | 2025 | C | 2250 rpm |
3 | Raydon Rocha | AZ | Mica Mountain High | 2026 | SS | 2135 rpm |
4 | Gabriel A Mendoza | AZ | Millenium | 2025 | LHP | 2122 rpm |
5 | Henry Verhamme | AZ | Cactus Shadows High School | 2026 | SS | 2087 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 | Rafael Echeverria | AZ | Rio Rico | 2025 | LHP | 17.1 in |
2 | Michel Muniz Jr | AZ | Sunnyside | 2025 | C | 14.1 in |
3 | Brayden Hoyler | AZ | Canyon Del Oro High School | 2027 | SS | 13.8 in |
4 | Henry Verhamme | AZ | Cactus Shadows High School | 2026 | SS | 13.6 in |
5 | Raydon Rocha | AZ | Mica Mountain High | 2026 | SS | 12.6 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 | Brayden Hoyler | AZ | Canyon Del Oro High School | 2027 | SS | 8.9 |
2 | Rafael Echeverria | AZ | Rio Rico | 2025 | LHP | -8.6 |
3 | Henry Verhamme | AZ | Cactus Shadows High School | 2026 | SS | 8.1 |
4 | Raydon Rocha | AZ | Mica Mountain High | 2026 | SS | 7.0 |
5 | Michel Muniz Jr | AZ | Sunnyside | 2025 | C | 5.0 |
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.”
