Prep Baseball Texas Staff

On Tuesday, June 2nd, the PB Texas staff traveled to Rice University in Houston, TX, to host the Houston Summer ID, an open event for all high school classes.

More than 40 players made their way to Rice 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.

VISUAL EDGE

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

EDGE SCORE

Rank	Name	State	School	Class	Pos	Edge Score
1	Grant Larson	TX	Seven Lakes	2028	RHP	81.16
2	Emmett DeCook	TX	The John Cooper School	2030	C	80.03

4	Reice Kargel	TX	Cypress Ranch	2027	C	76.66
5	Lance Jeffers	TX	Palestine	2027	OF	76.41

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.
