2026 Seattle Summer Review - Data Dive

August 8, 2026
Dylan Grenz
Assistant Scouting Director

On Tuesday August 4th, Prep Baseball Washington hosted the Seattle Summer Review at Island Crest Park in Mercer Island, WA. Prep Baseball scouts evaluated high school athletes in the 2027-2030 graduating classes, with several strong showings throughout the event.

Summer events serve as an important tool for both Prep Baseball 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 at 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 2026 Pacific Northwest State Games.

Earlier, we released our Quick Hits, detailing scouting notes on standout players from the event, and our Statistical Analysis, looking at leaders in major stat categories. Today, we conclude our post-event content with our Data Dive, focusing on more specific stat leaders on both sides of the baseball. For all other post-event content, click here.

Body Rotation: A swing that has the appropriate relative contributions of body and bat rotations is an efficient and Powerful swing that maintains proper sequencing. An efficient baseball swing is one in which the body creates the initial movements, which is then transferred to the arms and out to the bat, thereby maximizing Bat Speed through this proximal-to-distal kinematic sequencing movement pattern.

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. Think of the Edge Score as the 'Sixth Metric' in the standard Five-Tools that make up a ball player.

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.

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.
