Seattle Summer ID - Positional Data Dive


Dylan Grenz
Associate Scout

Last week, Prep Baseball staff hosted the Seattle Summer ID at Island Crest Park in Mercer Island, WA. Featuring prospects in the 2025-2028 classes, players from across the state participated in this showcase-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 Quick Hits, where we highlighted some standout performers from the ID event, and our Statistical Analysis, where we highlighted top performers in traditional statistical categories. Today, we release our Positional Data Dive, where we showcase leaderboards in more complex position player data categories.

TRACKMAN

EXIT VELOCITY (MAX)

EXIT VELOCITY (AVG.)

Exit Velocity: This metric measures the speed of the ball, measured in miles per hour, as it comes off the bat at the moment of contact.

BATTED BALL DISTANCE (MAX)

SWEET SPOT%

Sweet Spot percentage: This metric is determined by how often the player produces a batted ball during the session with a launch angle between 8 to 32 degrees.


BLAST MOTION

PEAK HAND SPEED (AVG.)

Hand Speed: The observed speed as measured on the handle of the bat (measured six inches from the knob of the bat). Peak Hand Speed will occur prior to the moment of impact, very close to the commit time in the swing when the wrists unhinge.

PEAK BAT SPEED (AVG.)

Bat Speed: The observed speed of the sweet spot of the bat at impact. The sweet spot of the bat is measured six inches from the tip of the bat.

ROTATIONAL ACCELERATION (AVG.)

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.

VIZUAL EDGE

EDGE SCORE

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.
