Seattle Preseason ID, Session II - Positional Data Dive
February 15, 2024
On Saturday, February 10th, Prep Baseball Washington staff hosted the Seattle Preseason ID - Session II at Mariners Training Center in Puyallup, WA. Featuring prospects in the 2024-2028 classes, over 40 players from across the state participated in this pro-style workout. The event included unrivaled access to data through our state-of-the-art technology partners, as well as in-depth scouting analysis from our Prep Baseball Washington staff.
Preseason 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 spring coverage. We also tend to see prospects’ best performances in the preseason, as most athletes are fresh and coming off of strict and targeted off-season training programs that have resulted in big gains, primed for updating their Prep Baseball profile. Exceptional performances lend the opportunity to secure invitations to some of the summer's biggest invite-only events, including Top Prospect Games, Prep Baseball Future Games, and more.
Earlier this week, we published our Quick Hits, where we dove into some of the top players from the event, and our Statistical Analysis, where we broke down the stat leaders from the more traditional categories. Today, we will take a further in-depth look at the positional player data, collected via Swift, Trackman, Blast, and Vizual Edge.

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
Rank | Name | State | School | Class | Pos | Edge Score |
1 | Tate Stearns | WA | North Kitsap | 2025 | OF | 88.59 |

4 | Braden Bartholomae | WA | Skyline | 2025 | OF | 77.88 |
5 | Izmael Hernandez | WA | Juanita | 2027 | OF | 77.26 |
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.
