Prep Baseball Report

Hawaii PSAS: Underclass Pitching Data


RJ Elmore
Western Operations Director

PEARL CITY, HI - The Hawaii Preseason All-State, one of the premier events on the Prep Baseball calendar, was held on Saturday, January 17 and Sunday, January 18th at Pearl City High School in Oahu, HI. This invite-only showcase featured top prospects from the 2026-2030 classes, each looking to make a statement ahead of the spring season.

Participants took part in an extended, pro-style workout that included batting practice tracked by TrackMan and Blast Motion, 60-yard dash testing powered by VALD Performance, and a full defensive evaluation. Pitchers threw in live games, capturing advanced metrics via our TrackMan unit such as pitch velocity, spin rate, and horizontal and vertical movement. The event featured a strong mix of familiar standouts continuing to build on previous performances, along with several new names who emerged with eye-opening showings.

14 Austin McIntosh HI Punahou 2028 OF 77.6 mph
15 Eli Iopa HI Mid Pacific Institute 2028 SS 77.0 mph

Max Fastball Velocity: This metric calculates the speed of the pitch as it’s released from the pitcher’s hand.

HIGHEST AVG. SPIN RATE

Rank Name State School Class Pos Spin Rate (avg) Velocity (max)
1 Noah Andrew Castillo HI Kamehameha Schools Kapalama Campus 2028 RHP 2400 rpm 87.6 mph
2 Kaiea Keliipuleole HI Kamehameha Schools Kapalama Campus 2028 OF 2375 rpm 80.1 mph

4 Ajay Moss HI Mililani 2029 OF 2116 rpm 81.3 mph
5 Noah Keitzer HI University Lab 2028 SS 2096 rpm 79.5 mph
6 Eli Iopa HI Mid Pacific Institute 2028 SS 2094 rpm 77.0 mph
7 Daly Watson HI Punahou 2028 SS 2031 rpm 84.3 mph
8 Reyn Minami HI Iolani 2028 RHP 2003 rpm 79.9 mph
9 Kaisen Montero HI Kamehameha Schools Kapalama Campus 2028 1B 2002 rpm 81.4 mph
10 Ka’imiIke Kamoku HI Kamehameha Schools Maui Campus 2028 RHP 1963 rpm 82.6 mph

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.

HIGHEST AVG. IVB

Rank Name State School Class Pos IVB (avg) Velocity (max)
1 Kini Lancaster HI Hilo Intermediate School 2030 SS 21.9 in 75.9 mph
2 Ajay Moss HI Mililani 2029 OF 20.1 in 81.3 mph
3 Ka’imiIke Kamoku HI Kamehameha Schools Maui Campus 2028 RHP 19.8 in 82.6 mph
4 Boston Schwager HI Kamehameha Schools Kapalama Campus 2028 LHP 19.1 in 80.9 mph
5 Kade Manarpaac HI Waiakea Intermediate School 2030 OF 19.1 in 75.8 mph
6 Koamalu Halemanu HI Waiakea Intermediate School 2030 C 18.2 in 61.9 mph
7 Patrick Ah Yat HI Kamehameha Schools Kapalama Campus 2029 OF 16.9 in 69.7 mph
8 Noah Keitzer HI University Lab 2028 SS 16.5 in 79.5 mph
9 Jake Nishimoto HI Mililani High School 2028 OF 16.5 in 83.4 mph
10 Eli Iopa HI Mid Pacific Institute 2028 SS 16.3 in 77.0 mph

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, and it’s also important to consider the pitch’s velocity as well as its release height when evaluating IVB measurements against each other.

HIGHEST AVG. HORIZONTAL MOVEMENT

Rank Name State School Class Pos HM (avg) Velocity (max)
1 Patrick Ah Yat HI Kamehameha Schools Kapalama Campus 2029 OF 18.6 69.7 mph
2 Noah Keitzer HI University Lab 2028 SS 17.8 79.5 mph
3 Noah Andrew Castillo HI Kamehameha Schools Kapalama Campus 2028 RHP 17.4 87.6 mph
4 Kanaloa Keli’ikoa Lee HI Kamehameha Schools Hawai'i 2030 RHP 14.9 75.6 mph
5 Mikah Noda HI Waipahu 2028 SS 14.6 82.8 mph
6 Jake Nishimoto HI Mililani High School 2028 OF 13.8 83.4 mph
7 Ajay Moss HI Mililani 2029 OF 12.6 81.3 mph
8 Kade Manarpaac HI Waiakea Intermediate School 2030 OF 12.4 75.8 mph
9 Koamalu Halemanu HI Waiakea Intermediate School 2030 C 12.1 61.9 mph
10 Reyn Minami HI Iolani 2028 RHP 11.3 79.9 mph

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.
