Texas State Games Underclass: Pitcher Data Dive

November 14, 2025
Prep Baseball Texas Staff

On Saturday, November 8th, the PB Texas staff traveled to Sam Houston State University in Huntsville, TX, to host the Texas State Games: Underclass, an invite-only event for the class of 2028 and 2029.

More than 80 players made their way to Sam Houston this past weekend and participated in a pro-style workout as well as gameplay, gathering unrivaled access to data through our state-of-the-art tech partners, while receiving in-depth scouting analysis from our Prep Baseball Texas staff.

We've already posted a Statistical Analysis from the event, highlighting more of the traditional statistical categories, as well as a Takeaways, highlighting some of the events top performers. We also highlighted some of the top positional players within this Data Dive story.

Today, we will be looking at the top measurable data performers from the event, found below.

4	Caleb Kahoalii	TX	Cypress Woods	2029	RHP	87.9 mph
5	Logan Starnes	TX	Dripping Springs	2028	RHP	87.5 mph

SPIN RATE (AVG.)

Rank	Name	State	School	Class	Pos	Spin Rate (avg)
1	Caleb Kahoalii	TX	Cypress Woods	2029	RHP	2323 rpm
2	William Broussard	TX	McKinney North	2028	RHP	2317 rpm
3	Trey Brooks	TX	Goose Creek	2028	SS	2306 rpm
4	Cooper Albart	TX	Martin	2028	C	2259 rpm
5	Brennan Ball	TX	Brewer H S	2029	OF	2222 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	Court Stephens	TX	Episcopal	2028	LHP	19.7 in
2	Reid Overstreet	TX	Rockwall	2028	LHP	19.4 in
3	Tony Ciurca	TX	Clear Falls	2028	SS	18.6 in
4	Caleb Kahoalii	TX	Cypress Woods	2029	RHP	18.5 in
5	Miles Swanson	TX	Allen	2029	C	18.0 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 efficiencies. 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 vertical approach angle.

HORIZONTAL MOVEMENT (AVG.)

Rank	Name	State	School	Class	Pos	HM (avg)
1	Cooper Knight	TX	Buda Johnson	2029	1B	-17.0
2	Court Stephens	TX	Episcopal	2028	LHP	-16.2
3	Heston Horn	TX	Mount Pleasant	2029	OF	-16.1
4	Carter Holder	TX	Concordia Lutheran	2029	OF	14.4
5	Eli Klanika	TX	Axtell El	2029	RHP	14.3

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.”

STRIKE ZONE RATE%

Rank	Name	State	School	Class	Pos	Zone %
1	Ayden Pulfer	TX	Magnolia	2029	3B	78 %

Average MLB pitchers throw 62% strikes, and better pitchers throw strikes 65% of the time, or roughly 2:1 strikes to balls.
