DK Leaderboard: Class of 2021 Metrics | Class of 2022 Metrics | Class of 2023 Metrics
Throughout the partnership between Perfect Game and Diamond Kinetics, thousands of players have had their swing metrics recorded as every player is tested during any Perfect Game Showcase. Below is a table, as well as a breakdown of the three key components Diamond Kinetics tracks (Max Barrel Speed, Max Acceleration and Impact Momentum), before we look at the top recordings from this past calendar year.

(The three metrics that most elite hitter have in common are 70-Max Barrel Speed, 45-Max Acceleration, and 27-Impact Momentum)
Speed
Bat speed is a crucial factor in creating a high amount of ball exit velocity, which directly correlates with how far and how fast the ball will travel after impact. There are four parts to the overall Speed metric: Speed Efficiency, Max Hand Speed, Forward Bat Speed and Max Barrel Speed.
*Max Barrel Speed
-The maximum speed of the bat’s barrel during your swing, at a point 20% from the tip of the bat.
Power
Power at its core is a measure of energy and how that energy is transferred to the ball at contact. Power is directly related to speed, but also includes such important factors as the mass and acceleration of the bat. There are three parts to the overall Power score: Applied Power, Max Acceleration, Impact Momentum.
*Max Acceleration
-Maximum Acceleration captures how quickly a batter speeds up their swing from start to impact, and relates directly to the force and torque applied to the bat.
*Impact Momentum
-Impact Momentum is the amount of the momentum in the bat when the bat makes contact with the ball. It is determined by the barrel speed at impact, and the weight of the bat.
