Top Prospect Games South Texas Data Dive: Pitchers


PBR Texas Staff

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 TAYLOR H S 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 TAYLOR H S 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 H S 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.”
