2024 Colorado Summer Kick Off: Pitching Data Dive
June 6, 2024
On Tuesday, June 4th, the Prep Baseball Colorado staff hosted the Colorado Summer Kick Off event at Metro State University in Denver, Colorado. This event featured ~30 prospects from the 2025 - 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.

FASTBALL
MAX VELOCITY (MPH)
Rank | Name | State | School | Class | Pos | Velocity (max) |
1 | Noah Stopnik | CO | Mountain Vista | 2025 | RHP | 87.5 mph |
2 | Cael Knobbe | CO | Cherry Creek | 2025 | RHP | 83.7 mph |
3 | Simon Lunsford | CO | Green Mountain High School | 2025 | RHP | 82.7 mph |
4 | Drake Jenkins | CO | Timnath | 2026 | OF | 80.6 mph |
5 | Sawyer Morgan | CO | Highland High School | 2025 | RHP | 80.5 mph |
6 | CJ Mahoney | CO | Lakewood | 2025 | LHP | 79.6 mph |
7 | Jake Clark | CO | Mullen | 2027 | RHP | 77.8 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 | Simon Lunsford | CO | Green Mountain High School | 2025 | RHP | 2457 rpm |
2 | Cael Knobbe | CO | Cherry Creek | 2025 | RHP | 2304 rpm |
3 | Noah Stopnik | CO | Mountain Vista | 2025 | RHP | 2291 rpm |
4 | Jack Berendes | CO | Evergreen High School | 2027 | RHP | 2198 rpm |
5 | Jake Clark | CO | Mullen | 2027 | RHP | 2054 rpm |
6 | CJ Mahoney | CO | Lakewood | 2025 | LHP | 2000 rpm |
7 | Drake Jenkins | CO | Timnath | 2026 | OF | 1943 rpm |
8 | Ryan Strouse | CO | Cherry Creek High School | 2026 | RHP | 1880 rpm |
9 | Sawyer Morgan | CO | Highland High School | 2025 | RHP | 1661 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 | Jack Berendes | CO | Evergreen High School | 2027 | RHP | 14.8 in |
2 | Drake Jenkins | CO | Timnath | 2026 | OF | 13.9 in |
3 | Sawyer Morgan | CO | Highland High School | 2025 | RHP | 11.1 in |
4 | Simon Lunsford | CO | Green Mountain High School | 2025 | RHP | 10.1 in |
5 | CJ Mahoney | CO | Lakewood | 2025 | LHP | 9.9 in |
6 | Noah Stopnik | CO | Mountain Vista | 2025 | RHP | 8.6 in |
7 | Jake Clark | CO | Mullen | 2027 | RHP | 8.6 in |
8 | Ryan Strouse | CO | Cherry Creek High School | 2026 | RHP | 7.9 in |
9 | Cael Knobbe | CO | Cherry Creek | 2025 | RHP | 5.7 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 MOVEMENT (AVG.)
Rank | Name | State | School | Class | Pos | HM (avg) |

2 | Noah Stopnik | CO | Mountain Vista | 2025 | RHP | 9.9 |
3 | Sawyer Morgan | CO | Highland High School | 2025 | RHP | 9.3 |
4 | Jake Clark | CO | Mullen | 2027 | RHP | 8.7 |
5 | Cael Knobbe | CO | Cherry Creek | 2025 | RHP | 7.8 |

8 | Jack Berendes | CO | Evergreen High School | 2027 | RHP | 3.6 |
9 | Drake Jenkins | CO | Timnath | 2026 | OF | -0.3 |
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.”
