Preseason ProCase: Positional Data Dive
February 2, 2024
On Jan. 31, the Prep Baseball Illinois staff hosted the Preseason ProCase at Rhino Sports Academy in Shorewood, Ill. This event featured 20 prospects, most of whom are Illinois natives and few from Wisconsin, and allowed our staff as well as the MLB scouts in attendance the opportunity to get an in-depth look at the players in attendance.
Yesterday, we looked at the top measurable data performers from the event, found in 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 top positional prospects with the help from our tech partnerships, broken down by the categories down below:

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 yards, 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.

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.\
