Prep Baseball Report events across the country have been powered by TrackMan’s industry-leading Portable system and Blast Sensor technology to capture pinpoint accurate, actionable data from player performances. Prep Baseball Report, TrackMan, and Blast are dedicated to recognizing talent and unleashing their potential.
Data collected by TrackMan has become significantly important for high school, Juco, and 4-year players. College programs have evolved beyond radar velocity readings, looking deeper into a pitcher's ability to spin and move the ball. In addition to velocity, TrackMan provides pitchers with valuable data points such as spin rate, spin direction, horizontal movement, vertical movement, and more. Ultimately providing feedback to college coaches, MLB scouts, and the players themselves; to enhance training and also to identify prospects of interest above and beyond simple velocity readings.
At PBR California showcases and events, amateur players now have access to the same technology shared by professionals and are able to see how their pitching arsenal compares with those across the state and the country. The TrackMan Arsenal Analysis will highlight those metrics and explain the benefits behind the numbers.

Max Fastball Velocity
The maximum velocity of the pitch measured right at release.
Rank | Name | State | School | Class | Pos | Velocity (max) |
1 | Grant Voss | CA | Liberty High | 2024 | OF | 85.1 mph |
2 | Cristian Ayala | CA | Bonita Vista | 2025 | 2B | 82.1 mph |
3 | Ryan Kehoe | CA | Eleanor Roosevelt | 2026 | RHP | 81.6 mph |
4 | Ian Brown | CA | Redondo Union | 2026 | OF | 80.1 mph |
5 | Jonas Nalu | CA | Cathedral Catholic | 2026 | SS | 78.9 mph |
6 | Riley Nelson | CA | Santa Fe Christian | 2027 | OF | 76.4 mph |
7 | Diego Matsumoto | CA | Clairemont | 2025 | 2B | 76.4 mph |
8 | Mario Vitale III | CA | Saint Augustine | 2027 | SS | 75.9 mph |
Max Fastball Spin Rate
The max amount of revolutions per minute (rpm) of a pitch. For fastballs, a higher rpm causes the ball to drop less due to gravity, this gives the illusion of a rising pitch.
Rank | Name | State | School | Class | Pos | Spin Rate (max) |
1 | Cristian Ayala | CA | Bonita Vista | 2025 | 2B | 2277 rpm |
2 | Mario Vitale III | CA | Saint Augustine | 2027 | SS | 2114 rpm |
3 | Riley Nelson | CA | Santa Fe Christian | 2027 | OF | 2073 rpm |
4 | Grant Voss | CA | Liberty High | 2024 | OF | 2053 rpm |
5 | Diego Matsumoto | CA | Clairemont | 2025 | 2B | 1896 rpm |
6 | Jonas Nalu | CA | Cathedral Catholic | 2026 | SS | 1894 rpm |
7 | Ryan Kehoe | CA | Eleanor Roosevelt | 2026 | RHP | 1890 rpm |
8 | Ian Brown | CA | Redondo Union | 2026 | OF | 1835 rpm |
Max Curveball Velocity
Like many things in baseball, the faster the better. A fast off-speed pitch while maintaining traditional movement patterns makes the pitch harder to hit. The measured velocity for this metric is right as the pitch leaves the hand.
Rank | Name | State | School | Class | Pos | Velocity (max) |
1 | Ryan Kehoe | CA | Eleanor Roosevelt | 2026 | RHP | 80.3 mph |
2 | Grant Voss | CA | Liberty High | 2024 | OF | 74.7 mph |
3 | Ian Brown | CA | Redondo Union | 2026 | OF | 71.6 mph |
4 | Diego Matsumoto | CA | Clairemont | 2025 | 2B | 68.2 mph |
5 | Riley Nelson | CA | Santa Fe Christian | 2027 | OF | 65.4 mph |
Max Curveball Spin Rate
The spin rate for a curveball tends to be the highest among all the pitches in a pitcher's arsenal. A higher spin rate, measured in rpms, on a curveball generally means more downward movement when combined with the top spin of the pitch.
Rank | Name | State | School | Class | Pos | Spin Rate (max) |
1 | Grant Voss | CA | Liberty High | 2024 | OF | 2518 rpm |
2 | Ryan Kehoe | CA | Eleanor Roosevelt | 2026 | RHP | 2186 rpm |
3 | Diego Matsumoto | CA | Clairemont | 2025 | 2B | 2139 rpm |
4 | Ian Brown | CA | Redondo Union | 2026 | OF | 2059 rpm |
5 | Riley Nelson | CA | Santa Fe Christian | 2027 | OF | 1453 rpm |
Max Slider Velocity
Sliders generally are faster than most other off-speed pitches with less overall movement. This metric measures the speed of the slider when it comes out of the hand.
Rank | Name | State | School | Class | Pos | Velocity (max) |
1 | Ian Brown | CA | Redondo Union | 2026 | OF | 77.6 mph |
2 | Grant Voss | CA | Liberty High | 2024 | OF | 75.8 mph |
3 | Cristian Ayala | CA | Bonita Vista | 2025 | 2B | 72.1 mph |
4 | Jonas Nalu | CA | Cathedral Catholic | 2026 | SS | 70.7 mph |
5 | Diego Matsumoto | CA | Clairemont | 2025 | 2B | 67.1 mph |
6 | Mario Vitale III | CA | Saint Augustine | 2027 | SS | 62.8 mph |
Max Slider Spin Rate
The higher the spin rate for a horizontal pitch like the slider means that it will have more movement from right to left for a right handed pitcher. This metric measures the maximum spin rate of a pitcher's slider in rpms.
Rank | Name | State | School | Class | Pos | Spin Rate (max) |
1 | Grant Voss | CA | Liberty High | 2024 | OF | 2654 rpm |
2 | Cristian Ayala | CA | Bonita Vista | 2025 | 2B | 2386 rpm |
3 | Mario Vitale III | CA | Saint Augustine | 2027 | SS | 2160 rpm |
4 | Diego Matsumoto | CA | Clairemont | 2025 | 2B | 2131 rpm |
5 | Ian Brown | CA | Redondo Union | 2026 | OF | 2081 rpm |
6 | Jonas Nalu | CA | Cathedral Catholic | 2026 | SS | 1983 rpm |
Max Changeup Velocity
This metric determines the speed of a changeup as it is released from the pitcher's hand.
Rank | Name | State | School | Class | Pos | Velocity (max) |
1 | Cristian Ayala | CA | Bonita Vista | 2025 | 2B | 76.8 mph |
2 | Riley Nelson | CA | Santa Fe Christian | 2027 | OF | 76.3 mph |
3 | Ryan Kehoe | CA | Eleanor Roosevelt | 2026 | RHP | 75.3 mph |
4 | Ian Brown | CA | Redondo Union | 2026 | OF | 73.8 mph |
5 | Jonas Nalu | CA | Cathedral Catholic | 2026 | SS | 72.2 mph |
6 | Mario Vitale III | CA | Saint Augustine | 2027 | SS | 68.7 mph |
Max Changeup Spin Rate
This metric shows how fast the ball is spinning during the pitch, measured by rpms.
Rank | Name | State | School | Class | Pos | Spin Rate (max) |
1 | Riley Nelson | CA | Santa Fe Christian | 2027 | OF | 2059 rpm |
2 | Ryan Kehoe | CA | Eleanor Roosevelt | 2026 | RHP | 2054 rpm |
3 | Ian Brown | CA | Redondo Union | 2026 | OF | 1965 rpm |
4 | Cristian Ayala | CA | Bonita Vista | 2025 | 2B | 1814 rpm |
5 | Mario Vitale III | CA | Saint Augustine | 2027 | SS | 1743 rpm |
6 | Jonas Nalu | CA | Cathedral Catholic | 2026 | SS | 1181 rpm |
