March 6, 2026
On March 1st, the Prep Baseball Wisconsin staff hosted the Green Bay Preseason ID at Impact Sports Academy in De Pere, WI. Over 125 players 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 Wisconsin staff.
We've already posted a Statistical Analysis from the event, highlighting more of the traditional statistical categories. Also, we released our Quick Hits story, highlighting some of the event's top performers.
Today, we will take a further in-depth look at the top positional players with the help of our tech partnerships, broken down by the categories down below:

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.

BAT SPEED (AVERAGE)
| Rank | Name | State | School | Class | Pos | Bat Speed (avg) |
| 1 | Brayden Grzelak | WI | Oconto Falls | 2028 | 1B | 77.1 mph |

| 8 | Bryce Urban | WI | Kaukauna | 2027 | C | 73.6 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 | Josh Kelley | WI | West De Pere | 2027 | 1B | 23.7 g |
| 2 | Tanner Proulx | WI | De Pere | 2027 | OF | 22.6 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 | Jackson Wisneski | WI | Kimberly | 2027 | 2B | 89 % |

| 7 | Dawson Meyer | WI | West De Pere High | 2029 | C | 85 % |
| 8 | Brody Harrison | WI | Ashwaubenon | 2027 | C | 85 % |
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%.

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.
