Prep Baseball Texas Staff

On Tuesday, June 9th, the PB Texas staff traveled to Tomball High School in Tomball, TX, to host the Tomball Summer ID, an open event for all high school classes.

More than 20 players made their way to Tomball HS 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 have already released a Statistical Analysis from the event, highlighting more of the traditional statistical categories, as well as a Quick Hits, highlighting some of the events top performers.

Today, we will be looking at the top measurable data performers from the event, found below.

60-YARD

Rank	Name	State	School	Class	Pos	60-yd
1	Jonell Rodriguez	TX	Oakridge	2027	2B	6.65 s

10-YARD SPLIT

Rank	Name	State	School	Class	Pos	10-yd
1	Yusiel Cordero Peguero	TX	Langham Creek H S	2027	OF	1.66 s
2	Matthew Gray	TX	Cypress Ranch	2027	OF	1.67 s
3	Jonell Rodriguez	TX	Oakridge	2027	2B	1.70 s
^	Calvin Rice	WA	North Mason	2027	C	1.70 s

4	Payton Archibald	TX	Frenship	2028	1B	1.71 s
5	Braison Clevenger	MO	Acellus Academy	2027	OF	1.72 s

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.

MAX VERTICAL JUMP

Rank	Name	State	School	Class	Pos	Jump Height (max)
1	Zachary Rosko	TX	Tomball Memorial	2027	SS	28.0

3	Braison Clevenger	MO	Acellus Academy	2027	OF	25.0

^	Thomas Grubert	TX	Tompkins	2028	C	24.0

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.

VISUAL EDGE

A look at the top Vizual Edge scores from the event.

EDGE SCORE

Rank	Name	State	School	Class	Pos	Edge Score
1	Emmett DeCook	TX	The John Cooper School	2030	C	79.47
2	Zachary Rosko	TX	Tomball Memorial	2027	SS	76.56
3	Colton Davis	TX	Calallen H S	2027	OF	76.33
4	Yusiel Cordero Peguero	TX	Langham Creek H S	2027	OF	72.77
5	Braison Clevenger	MO	Acellus Academy	2027	OF	72.75

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.
