Denver Preseason ID: Pitching Data Dive


Caleb Dameron
Prep Baseball Colorado Staff

On Saturday, February 17th, the Prep Baseball Colorado staff hosted the Denver Preseason ID at the Marucci Clubhouse in Castle Rock, Colorado. This event featured ~60 prospects from the 2024 - 2027 classes and allowed our staff an opportunity to get an in-depth look at the players in attendance.

We 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.

FASTBALL

Rank Name State School Class Pos Velocity (max)
1 Ian Stephenitch CO Lutheran 2025 RHP 86.5 mph
2 Cade Petersen CO Lutheran 2026 RHP 86.4 mph
3 Easton Embrey CO Palisade High School 2025 RHP 86.1 mph
4 Michael Kroll CO Regis Jesuit 2027 RHP 85.7 mph
5 Ryan Prater CO Pine Creek 2026 LHP 85.7 mph
6 Riley Suddath CO Chatfield 2025 RHP 85.5 mph
7 Connor Brennan CO Eaglecrest 2025 LHP 85.3 mph

9 Cosme Jr Vera CO Eaglecrest 2025 OF 84.0 mph
10 Winston Patterson CO Ralston Valley 2027 RHP 83.9 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 Brigham Brown CO Valor Christian 2025 RHP 2265 rpm
2 Leo Zimmerman CO Manual 2025 RHP 2171 rpm

4 Lars Jergensen CO Ralston Valley 2027 RHP 2136 rpm

7 Matthew Marocchi CO Cherry Creek 2026 2B 2112 rpm
8 Easton Embrey CO Palisade High School 2025 RHP 2102 rpm
9 Cade Stephenitch CO Lutheran 2026 LHP 2101 rpm
10 Brayden Reiner CO Arvada West 2026 C 2092 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.)

10 Ian Stephenitch CO Lutheran 2025 RHP 11.9 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.”
