San Diego Fall ID: TrackMan Pitching Leaderboards


Matt Monk

   

SAN DIEGO, CALIF. - Players gathered at Maranatha Christian School for the San Diego Fall ID. They were run through a traditional workout which evaluated their speed, fielding, catching, and pitching. Keep a lookout in the coming days for leaderboards from this event.

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
