2024 ProCase - West: TrackMan Pitching Leaders
June 4, 2024
Malibu, CA – The Prep Baseball Procase West brought together the most talented underclass MLB Draft prospects to compete at the scenic Eddy D. Field Stadium on the campus of Pepperdine. Although the page has not been turned on the ‘24 MLB Draft, the summer circuit for next year’s has begun, and the large crop of scouts in attendance were set to begin “double duty” (and triple duty with some of the ‘26s). The many talented rising seniors of the 2025 class showcased their skills across a full workout followed by a game. Every player in attendance was a draft prospect.
Below, we take a look at the top pitching metrics, via TrackMan, from the event.
FASTBALL
MAX VELOCITY (MPH)
Rank | Name | State | School | Class | Pos | Velocity (max) |
1 | Zach Strickland | CA | Maranatha | 2025 | RHP | 95.8 mph |
2 | Alexander Mercurius | NV | Durango High School | 2025 | RHP | 94.7 mph |
3 | Ethin Bingaman | CA | Corona High School | 2025 | RHP | 93.8 mph |
4 | Angel Cervantes | CA | Warren High | 2025 | RHP | 93.6 mph |
5 | Grayson Boles | CA | ST AUGUSTINE ACADEMY | 2025 | RHP | 92.3 mph |
6 | Jaxon Baker | CA | Paloma Valley High | 2025 | LHP | 91.4 mph |
7 | Dylan Harrison | CA | Summit High | 2025 | RHP | 91.3 mph |
8 | Dylan Singleton | UT | PDG Academy | 2025 | LHP | 90.6 mph |
9 | Colton Christman | NV | Arbor View | 2026 | LHP | 90.5 mph |
10 | Andrew Jacobs | AZ | Mountain Ridge High School | 2025 | RHP | 90.5 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 | Ethin Bingaman | CA | Corona High School | 2025 | RHP | 2523 rpm |
2 | Chase Johnston | UT | Maple Mountain High | 2025 | LHP | 2434 rpm |
3 | Angel Cervantes | CA | Warren High | 2025 | RHP | 2353 rpm |
4 | Dylan Singleton | UT | PDG Academy | 2025 | LHP | 2347 rpm |
5 | Ethan Iacono | UT | Mountain Ridge High | 2025 | RHP | 2317 rpm |
6 | Andrew Jacobs | AZ | Mountain Ridge High School | 2025 | RHP | 2303 rpm |
7 | Trey Morris | CA | Washington Union | 2025 | LHP | 2267 rpm |
8 | Dylan Harrison | CA | Summit High | 2025 | RHP | 2234 rpm |
9 | Grayson Boles | CA | ST AUGUSTINE ACADEMY | 2025 | RHP | 2231 rpm |
10 | Zach Strickland | CA | Maranatha | 2025 | RHP | 2226 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 | Ethin Bingaman | CA | Corona High School | 2025 | RHP | 20.3 in |
2 | Chase Johnston | UT | Maple Mountain High | 2025 | LHP | 18.6 in |
3 | Zach Strickland | CA | Maranatha | 2025 | RHP | 18.1 in |
4 | Alexander Mercurius | NV | Durango High School | 2025 | RHP | 15.4 in |
5 | Cody Kiemele | CA | Arlington High | 2025 | LHP | 15.3 in |
6 | Dylan Harrison | CA | Summit High | 2025 | RHP | 15.2 in |
7 | Holden Potter | UT | Bear River High | 2025 | RHP | 15.1 in |
8 | Angel Cervantes | CA | Warren High | 2025 | RHP | 14.8 in |
9 | Dylan Singleton | UT | PDG Academy | 2025 | LHP | 14.0 in |
10 | Ethan Iacono | UT | Mountain Ridge High | 2025 | RHP | 13.9 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 MOVEMENT (AVG.)

3 | Colton Christman | NV | Arbor View | 2026 | LHP | -14.9 |
4 | Dylan Singleton | UT | PDG Academy | 2025 | LHP | -14.5 |

6 | Andrew Jacobs | AZ | Mountain Ridge High School | 2025 | RHP | 14.2 |
7 | Caden Sramek | CA | Royal High | 2025 | RHP | 13.7 |
8 | Boston Kellner | AZ | Hamilton | 2025 | SS | 13.3 |
9 | Jaxon Baker | CA | Paloma Valley High | 2025 | LHP | -11.7 |
10 | Angel Cervantes | CA | Warren High | 2025 | RHP | 11.6 |
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.”
