San Diego Preseason All-State: Positional Data Dive
January 16, 2026

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:

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) |

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%.

| 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.
