Top Prospect Games South Texas Data Dive: Pitchers
July 7, 2023
On June 27, the PBR Texas team hosted the Top Prospect Games: South Texas at Texas A&M. The event was invite-only and featured quality prospects from all HS classes. The day consisted of a showcase portion, followed by gameplay. Today, we take a look at some of the top pitching metrics on the day.
FASTBALL
MAX VELOCITY (MPH)
Rank | Name | State | School | Class | Pos | Velocity (max) |
1 | Nicholas Bowman | TX | Rains ISD | 2024 | RHP | 88.1 mph |
2 | Donnie Edgar | TX | Saginaw | 2024 | RHP | 87.1 mph |
3 | Joseph Perillo | TX | Porter | 2025 | LHP | 86.7 mph |
4 | Cody Palacios | TX | Magnolia West | 2025 | OF | 86.5 mph |
5 | Mason Kinchen | TX | Grand Oaks | 2025 | LHP | 86.4 mph |
6 | Brandon Stewart | TX | Sweeny | 2024 | RHP | 85.8 mph |
7 | Caden Stambolis | TX | Katy Taylor | 2026 | RHP | 84.5 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 | Nicholas Bowman | TX | Rains ISD | 2024 | RHP | 2302 rpm |
2 | Caden Stambolis | TX | Katy Taylor | 2026 | RHP | 2206 rpm |
3 | Donnie Edgar | TX | Saginaw | 2024 | RHP | 2193 rpm |
4 | Joseph Perillo | TX | Porter | 2025 | LHP | 2137 rpm |
5 | Wyatt Clewett | TX | Montgomery | 2026 | 3B | 2128 rpm |
6 | Brandon Stewart | TX | Sweeny | 2024 | RHP | 2110 rpm |
7 | Cody Palacios | TX | Magnolia West | 2025 | OF | 2096 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 | Zachary Pearrow | TX | Waxahachie | 2024 | OF | 18.1 in |
2 | Wyatt Clewett | TX | Montgomery | 2026 | 3B | 17.4 in |
3 | Brody Durrett | TX | Ridge Point | 2026 | RHP | 16.8 in |
4 | Joseph Perillo | TX | Porter | 2025 | LHP | 16.5 in |
5 | Harper Heathcott | TX | Lake Creek | 2026 | LHP | 16.3 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 | Austin Glasscock | TX | Bridgeland | 2025 | 1B | -12.5 |
2 | Cody Palacios | TX | Magnolia West | 2025 | OF | 11.2 |
3 | Cole Johnson | TX | Pieper | 2026 | LHP | -11.1 |
4 | Will Coffman | TX | St. John's | 2025 | RHP | 10.3 |
5 | Hagen Tijerina | TX | Mabank | 2024 | LHP | -9.9 |
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.”
