Hawaii PSAS: Upperclass Statistical Analysis


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.

Stay tuned to our social media and website for the next coming weeks to see in-game/BP video, leaderboards, spotlights, and more.

Traditionally, the 60-yard dash has been the in-event standard to help measure a player's speed tool. We implemented three timing gates at the 10- and 30-yard splits, to capture athletes’ quickness, explosiveness and reaction time. From there, we will calculate an athlete’s top-end speed in miles per hour. While the measurement still has its utility, the 10-yard split has started to become more and more applicable in determining the player's burst and reaction time in-game, whether that's in the outfield or on the basepaths.

The Edge Score is a comprehensive score out of 100 that takes the core-six visual skills into account, providing athletes, parents, coaches and scouts with a benchmark number for assessing an athlete’s overall visual ability. In general, the higher the Edge Score, the higher chance of athletic success.

The average Edge Score for the 2020 MLB Draft Class was 79.3 (of hitters who completed a Vizual Edge test). MLB players we've worked with typically show stronger scores, with elite hitters scoring consistently above 87.0 on their Edge Score.
