Top Prospect Games San Marcos: Positional Data Dive
June 23, 2025
On Tuesday June 17th, the PB Texas staff traveled to Texas State University in San Marcos, TX, to host the Top Prospect Games: San Marcos, an invite-only event for the class of 2026-2028.
More than 35 players made their way to Texas State University 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 Texas staff.
We've already posted a Statistical Analysis from the event, highlighting more of the traditional statistical categories.
Today, we will be looking at the top measurable data performers from the event, found below.
VALD
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.
MAX VERTICAL JUMP
RSI
The ability to develop force quickly is a requisite ability in most sports. The Reactive Strength Index (RSI) has been developed as a measure of explosive strength and is derived by evaluating jump height divided by ground contact time during the depth jump. Regarding Vertical Jumps and its application to baseball, there have been studies conducted that show a correlation between max jump height for an athlete and their ability to generate power and strength, especially on the mound.
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.
