San Diego Preseason All-State: Positional Data Dive


By: Gavin Smith
Manager, Content & Operations

On Sunday, January 11th, the Prep Baseball California team hosted the San Diego Preseason All-State at Maranatha Christian HS in San Diego, Cal. This was an invite-only event for high school classes (2026-2029), and gave our staff an ample look at the area's top prospects.

Nearly 50 players made their way to Maranatha Christian 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.

Today, we will take a further in-depth look at the top position players with the help of our tech partnerships, broken down by the categories below:


VALD ATHLETIC TESTING

60-YARD

Rank Name State School Class Pos 60-yd
1 Joel Vargas CA Eastlake 2028 OF 6.63 s
2 Jonah Boyd CA Ruben S. Ayala High 2028 SS 6.65 s
3 Griffin Fien CA Chaparral High 2027 OF 6.66 s
4 Dane Disney CA Oaks Christian 2028 OF 6.71 s
5 Evan Skelskey CA Corona High School 2028 C 6.74 s
6 Ryan Sheffer CA Oaks Christian 2028 SS 6.77 s
7 Tyce Johnson CA Linfield Christian School 2028 SS 6.79 s
^ Maximus Villalva CA Christian JR/SR High School 2028 SS 6.79 s
8 Tyler Vladic CA Cypress 2027 OF 6.86 s
9 Maxwell Stewart CA Cathedral Catholic 2027 1B 6.94 s
10 Michael Ruiz CA St. Augustine 2026 SS 6.97 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.

BLAST

With the help of our Blast Motion sensors, we're analyzing the swing metrics measured at this open showcase.

HAND SPEED (AVERAGE)

Rank Name State School Class Pos Hand Speed (avg)
1 Maxwell Stewart CA Cathedral Catholic 2027 1B 23.3 mph
2 Brayden Geruntino CA Patrick Henry High School 2028 SS 23.0 mph
3 Romeo Briones CA Helix 2028 LHP 22.8 mph
4 Tyce Johnson CA Linfield Christian School 2028 SS 22.7 mph
5 Michael Ruiz CA St. Augustine 2026 SS 21.6 mph

Hand Speed: The observed speed as measured on the handle of the bat (measured six inches from the knob of the bat). Peak Hand Speed will occur prior to the moment of impact, very close to the commit time in the swing when the wrists unhinge.

BAT SPEED (AVERAGE)

Rank Name State School Class Pos Bat Speed (avg)
1 Maxwell Stewart CA Cathedral Catholic 2027 1B 79.5 mph
2 Ethan Miller CA Centennial High 2028 SS 76.7 mph
3 Romeo Briones CA Helix 2028 LHP 74.2 mph
4 Jose Ortega CA Calexico High 2026 RHP 73.6 mph
5 Maximus Villalva CA Christian JR/SR High School 2028 SS 73.5 mph
6 Joel Vargas CA Eastlake 2028 OF 73.4 mph
7 Wes Gomes CA Murrieta Valley High 2027 C 72.4 mph
8 Tyce Johnson CA Linfield Christian School 2028 SS 72.3 mph
9 Ryan Sheffer CA Oaks Christian 2028 SS 71.8 mph
10 Nicholas J Sanchez CA St. Augustine High School 2027 C 71.7 mph

Bat Speed: The observed speed of the sweet spot of the bat at impact. The sweet spot of the bat is measured six inches from the tip of the bat.

ROTATIONAL ACCELERATION (AVERAGE)

Rank Name State School Class Pos Rot. Acc (avg)
1 Maxwell Stewart CA Cathedral Catholic 2027 1B 25.9 g
2 Ryan Sheffer CA Oaks Christian 2028 SS 19.2 g
3 Brayden Geruntino CA Patrick Henry High School 2028 SS 19.0 g
4 Griffin Fien CA Chaparral High 2027 OF 18.1 g
5 Rhett Lopez CA Centennial High 2029 SS 17.2 g
6 Maximus Villalva CA Christian JR/SR High School 2028 SS 16.9 g
7 Deegan Holquin CA Buchanan High School 2029 RHP 15.4 g
8 Dane Disney CA Oaks Christian 2028 OF 15.2 g
9 Joel Vargas CA Eastlake 2028 OF 15.1 g
10 Michael Ruiz CA St. Augustine 2026 SS 14.1 g

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.

ON-PLANE EFFICIENCY %

Rank Name State School Class Pos On Plane Eff (avg)
1 Jonah Boyd CA Ruben S. Ayala High 2028 SS 87 %
2 Maximus Villalva CA Christian JR/SR High School 2028 SS 86 %
3 Robert Bering CA Carlsbad 2027 LHP 82 %
4 Griffin Fien CA Chaparral High 2027 OF 78 %
5 Max Adams CA Carlsbad 2027 SS 77 %
6 Joel Vargas CA Eastlake 2028 OF 71 %
7 Logan Miller CA Mater Dei 2027 C 71 %
8 Romeo Briones CA Helix 2028 LHP 69 %
9 Gavin Carcelen CA Los Osos High 2029 SS 69 %
10 Jonathan Sanchez CA Otay Ranch Senior High 2028 OF 69 %

On-Plane Efficiency %: measures the percentage of your swing where the bat is on the swing plane. Your Vertical Bat Angle (VBA) at contact establishes the plane for that specific swing. A high % is a great indicator of making consistent contact and barreling balls. Blast recommends an average of 70% or higher, with a range in the 65% to 85%.


VISUAL EDGE

9 Jose Ortega CA Calexico High 2026 RHP 72.10
10 Maximus Villalva CA Christian JR/SR High School 2028 SS 71.75

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.
