2023 PBR Hawaii State Games: Pitching Data Dive

On August 19th, Prep Baseball Report staff travelled to Hawaii to officially launch PBR Hawaii with a pair of events, highlighted by the Hawaii State Games. The inaugural event took place at the home of the University of Hawaii Rainbow Warriors, Les Murakami Stadium in Honolulu, Hawaii.

The event featured roughly 55 prospects from the 2024 - 2028 classes and allowed our staff an opportunity to get an in-depth first look at the talent in Hawaii, as well gather significant data on each player.

Earlier this week, we broke down the top measurable data performers from the event with our Statistical Analysis. Now, we will take a further in-depth look at the top pitchers with the help of our tech partnerships, broken down by the categories down below:

FASTBALL

MAX VELOCITY (MPH)

Rank Name State School Class Pos Velocity (max)
1 Joshua Surigao SC North Myrtle Beach 2024 LHP 91.6 mph
2 Elias Pereira HI Kauai 2024 3B 86.2 mph
3 Jayden Andrade HI Farrington 2024 RHP 84.7 mph
4 John Ganske HI Moanalua High School 2025 C 84.3 mph
5 Nakoa Moses-Gomera HI Kamehameha Schools Kapalama Campus 2024 RHP 83.8 mph
6 Koki Hayashi HI Kalani 2024 C 80.8 mph
7 Kylan Kono HI Waipahu 2024 SS 80.6 mph
8 Kolaiah Villa HI Lahainaluna 2027 SS 78.2 mph
9 Pi'ikoa Kamoku HI Kamehameha Maui 2026 C 77.9 mph
10 Colten Silva HI Saint Louis School 2026 SS 77.4 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 Kolaiah Villa HI Lahainaluna 2027 SS 2349 rpm
2 Colten Silva HI Saint Louis School 2026 SS 2080 rpm
3 Elias Pereira HI Kauai 2024 3B 2021 rpm
4 Koki Hayashi HI Kalani 2024 C 1992 rpm
5 Jayden Andrade HI Farrington 2024 RHP 1981 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 Ascher Van Zee HI Punahou 2026 RHP 22.6 in
2 Micah Polloi HI Wai?kea 2026 OF 18.2 in
3 Colten Silva HI Saint Louis School 2026 SS 14.7 in
4 Kylan Kono HI Waipahu 2024 SS 14.1 in
5 John Ganske HI Moanalua High School 2025 C 13.8 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)
1 Joshua Surigao SC North Myrtle Beach 2024 LHP -17.4
2 Nakoa Moses-Gomera HI Kamehameha Schools Kapalama Campus 2024 RHP 15.0
3 Kylan Kono HI Waipahu 2024 SS 12.6
4 Jovin Ezekiel Moises HI Waimea 2025 RHP 10.3
5 Jayden Andrade HI Farrington 2024 RHP 8.6

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.”
