LANCASTER, CALIF. - Last Wednesday, June 17th, the Prep Baseball California team is hosted the High Desert Summer ID at Antelope Valley College in Lancaster, Cal. This was an open event for all high school classes (2027-2030), and gave our staff an ample look at some of that area's and surrounding areas' top players.
Around 35 players made their way to Antelope Valley College and participated in a pro-style workout, gathering unrivaled access to data through our state-of-the-art tech partners, as well as in-depth scouting analysis from our Prep Baseball California staff. For a closer look at the showcase details and the technologies we had on-site to assist our in-person evaluation for all in attendance, click here.
To start the day, all position players in attendance were electronically measured for height, weighed in, and recorded grip strength readings. From there, they ran a 60-yard sprint with all split times being gathered using VALD Technologies' laser timing system. Upon completion of the athletic and body testing portion of the day, the players went into offensive evaluations with multiple rounds of batting practice, where Trackman Technologies and Blast Motion swing trackers were in use to gather batted ball and swing data on players in attendance, in addition under going Vizual Edge testing and VALD Jump testing. Which was then followed by defensive evaluations at their primary and secondary position (OF, C, SS, 1B) with arm strength being measured via a Stalker Radar gun and skill evaluations by our staff on hand. Once the batting practice portion of the event was completed, we shifted into the pitching portion of the day with pitchers throwing bullpens from the main mound with Trackman Technologies running to gather pitch data.
Today, we will be looking at some of the top performers in the advanced metrics collected on position players from the event, found below. For all of the event information, please click here.
VALD ATHLETIC TESTING
60-YARD
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.
10-Yard
30-Yard
MAX RUN SPEED
TRACKMAN
We'll continue to roll out the data we gathered from this event, starting with the analytics we have at our disposal from our TrackMan units. Below we'll look at which players had noteworthy batted ball and pitch data.
EXIT VELOCITY (MAX)
EXIT VELOCITY (AVERAGE)
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 (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.
Hard Hit %
VISUAL EDGE
A look at the top Vizual Edge scores from the event.
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.
