Portland Summer ID Session II - Pitching Data Dive


Dylan Grenz
Associate Scout

On July 2nd, Prep Baseball staff hosted Session II of our Portland Summer ID offerings. Featuring prospects in the 2025-2028 classes, players from Washington and Oregon participated in this pro-style workout. The event included unrivaled access to data through our state-of-the-art technology partners and in-depth scouting analysis from our Prep Baseball staff.

Summer ID events serve as an important tool for both PBR scouts and college recruiters, who will subsequently create lists of prospects to follow as they plan their remaining summer coverage. We often tend to see prospects' best showings in summer ID events, as players are fresh off playing for their respective high schools and are in the routine that consistently playing in-game offers. Standout performances can lend invites to some of the summer's top events, including the PBR Pacific Northwest State Games.

Earlier, we released our Statistical Analysis, where we showcased leaders in the traditional statistical categories, and our Positional Data Dive, where we unveiled leaders in position player data. Today, we release our Pitching Data Dive, looking specifically at leaders in pitching data metrics.

EFFECTIVE FB VELOCITY AVG

Effective velocity is taking into account the velocity of each pitch, its release distance, the pitches time to the plate / hitting area, and the pitches movement.  With all of this information, Effective Velocity is allowing coaches and scouts to more accurately compare how a pitch is affecting a hitter.
