Scottsdale Open: Pitching Data Dive
July 16, 2023
On July 11th, the PBR Arizona staff hosted the Scottsdale Open at Scottsdale Stadium, home of the San Francisco Giants Spring Training, in Scottsdale, Arizona. This event featured 44 prospects from the 2024 - 2027, including a slew of uncommitted talent 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. 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 | Vinnie Keck | AZ | Saguaro | 2026 | RHP | 86.7 mph |
2 | Jacques Berube | AZ | Basha | 2026 | RHP | 84.1 mph |
3 | Brody Johnson | AZ | Flagstaff | 2026 | RHP | 83.8 mph |
4 | Roman Carrington | AZ | Homeschool (AZ) | 2026 | SS | 82.3 mph |
5 | Vinny Noble | AZ | Brophy College Prep | 2026 | C | 81.3 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 | Trenten Seibert | AZ | Shadow Mountain | 2024 | RHP | 2152 rpm |
2 | Vinnie Keck | AZ | Saguaro | 2026 | RHP | 2119 rpm |
3 | Roman Carrington | AZ | Homeschool (AZ) | 2026 | SS | 2005 rpm |
4 | Brockton Reichwein | AZ | Perry | 2027 | LHP | 1982 rpm |
5 | Dean Thompson | AZ | Hamilton | 2027 | 1B | 1923 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 | Brockton Reichwein | AZ | Perry | 2027 | LHP | 17.7 in |
2 | Roman Carrington | AZ | Homeschool (AZ) | 2026 | SS | 16.2 in |
3 | Trenten Seibert | AZ | Shadow Mountain | 2024 | RHP | 15.5 in |
4 | Brady Winebrenner | AZ | Valley Christian | 2027 | RHP | 15.4 in |
5 | Vinnie Keck | AZ | Saguaro | 2026 | RHP | 15.1 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 | Brockton Reichwein | AZ | Perry | 2027 | LHP | -11.9 |
2 | Cole Smith | AZ | Horizon | 2025 | RHP | 10.5 |
3 | Vinnie Keck | AZ | Saguaro | 2026 | RHP | 10.4 |
4 | Trenten Seibert | AZ | Shadow Mountain | 2024 | RHP | 10.2 |
5 | Dean Thompson | AZ | Hamilton | 2027 | 1B | 8.2 |
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.”
