Colorado Preseason All-State: Pitching Data Dive


Caleb Dameron
Prep Baseball Colorado Staff

On Sunday, February 25th, the Prep Baseball Colorado staff hosted the Colorado Preseason All-State at The Farm Sports in Colorado Springs. This event featured ~170 prospects from the 2024 - 2027 classes and allowed our staff an opportunity to get an in-depth look at the players in attendance.

Today we'll continue our deep dive into the data collected at this event within this Pitching Data Dive story. Over the next couple of days we’ll be diving deeper into all of the data we collected rolling out even more coverage from the event.

Max Fastball Velocity: This metric calculates the speed of the pitch as it’s released from the pitcher’s hand.

SPIN RATE (AVG)

1 Ethan Wachsmann CO Grandview 2026 RHP 2555 rpm
2 Tyler Houston CO Legend 2026 RHP 2329 rpm
3 Josiah Hussey CO Erie 2025 OF 2324 rpm
4 Gunnar Garrison CO Eaton 2026 RHP 2287 rpm
5 Luc Gaca Thiele CO Fossil Ridge 2026 3B 2274 rpm
6 Maverick Scarpella CO Broomfield 2025 LHP 2264 rpm
7 Jack Weiss CO Grandview 2025 SS 2261 rpm
8 Nick Martensen CO Grandview 2025 LHP 2259 rpm
9 Anthony Graziano CO Cherry Creek 2025 RHP 2258 rpm
10 Jason Olsen CO Legacy 2025 SS 2242 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.)

9 Nick Martensen CO Grandview 2025 LHP 13.3 in
10 Hudson Griffith CO Legacy 2025 LHP 12.7 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 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.”
