Unsigned Senior Showcase: Pitching Data Dive
September 29, 2023
On Tuesday September 26th, the PBR Arizona staff hosted the Unsigned Senior Showcase at Grand Canyon University in Phoenix, Arizona. This event featured 53 uncommitted prospects from the senior class 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 and Quick Hits 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 | Tanner Ford | AZ | Boulder Creek | 2024 | RHP | 88.7 mph |
2 | Hunter Clark | AZ | Peoria High School | 2024 | 3B | 87.4 mph |
3 | Greg Mattison | AZ | Canyon View | 2024 | RHP | 87.2 mph |
4 | Adin Oeltjen | AZ | Cactus Shadows | 2024 | OF | 86.7 mph |
5 | Riley Schilling | WY | Thunder Basin | 2024 | C | 85.2 mph |
6 | Quinn Robertson | AZ | Desert Mountain | 2024 | RHP | 84.8 mph |
7 | Orlando Cobarrubias | AZ | Sunnyside | 2024 | OF | 84.1 mph |
8 | Zachary Stevens | AZ | Mountain Pointe | 2024 | OF | 84.0 mph |
9 | Ryan Miller | AZ | Willow Canyon | 2024 | RHP | 82.4 mph |
10 | Ethan Buckner | AZ | American Leadership Academy | 2024 | RHP | 81.8 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 | Santiago Hernandez | AZ | Saguaro | 2024 | SS | 2384 rpm |
2 | Trenten Seibert | AZ | Shadow Mountain | 2024 | RHP | 2230 rpm |
3 | Ryan Miller | AZ | Willow Canyon | 2024 | RHP | 2223 rpm |
4 | Hunter Clark | AZ | Peoria High School | 2024 | 3B | 2181 rpm |
5 | Greg Mattison | AZ | Canyon View | 2024 | RHP | 2176 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 | Tanner Ford | AZ | Boulder Creek | 2024 | RHP | 18.6 in |
2 | Zachary Stevens | AZ | Mountain Pointe | 2024 | OF | 18.1 in |
3 | Trenten Seibert | AZ | Shadow Mountain | 2024 | RHP | 16.6 in |
4 | Alfonso Trujillo | AZ | Tolleson Union | 2024 | OF | 15.4 in |
5 | Ryan Miller | AZ | Willow Canyon | 2024 | RHP | 15.3 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 | Jack Langley | AZ | Shadow Ridge | 2024 | RHP | 14.9 |
2 | Trenten Seibert | AZ | Shadow Mountain | 2024 | RHP | 13.6 |
3 | Ethan Buckner | AZ | American Leadership Academy | 2024 | RHP | 13.4 |
4 | Owen House | AZ | Willow Canyon | 2024 | OF | 12.6 |
5 | Riley Schilling | WY | Thunder Basin | 2024 | C | 11.4 |
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.”
