Metrics

Attack Angle – the angle of the bat’s path, at impact, relative to horizontal. A positive value indicates swinging up, and a negative value indicates swinging down, where zero is perfectly level.

Bat Speed – is 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.

Connection at Impact – measures the relationship between your body tilt and vertical bat angle at impact. Maintaining a good connection (90 degrees) for all pitch locations is an indicator of dynamic adjustability.

Connection Score – Scores your Early Connection and Connection (at impact) for each swing on the scouting scale of 20-80. Your score is based on how you compare to others at your level of play. The higher the score the better.

Early Connection – measures the relationship between your body tilt and vertical bat angle at the start of the downswing. Establishing a good connection (90 degrees) early in the swing helps you get on a plane and increases your ability to adjust to all pitch locations.

On Plane Efficiency – Measures the percentage of your swing where the bat is on the swing plane. Your vertical bat angle at contact establishes the plane for that swing. Plane is a great indicator for making more consistent contact on the barrel of the bat.

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

Plane Score – Scores your On Plane Efficiency for each swing on the scouting scale of 20-80. Your score is based on how you compare to others at your level of play. The higher the score the better.

Power – The average Power generated during the swing is found from the effective mass of the bat, the Bat Speed at impact, and the average acceleration during the downswing. Power is measured in Watts. Higher Power is achieved when a hitter can swing a heavier bat and accelerate it to higher speeds.

Rotation Score – Scores your Rotational Acceleration for each swing on the scouting scale of 20-80. Your score is based on how you compare to others at your level of play. The higher the score the better.

Rotation Acceleration – Rotation measures how quickly your bat accelerates into the swing plane. Rotation is a good indicator of how you build bat speed by sequencing properly vs. pulling the bat with your hands. The quicker your rotational acceleration, the more power you will have and the more time you have to decide on the plate.

Swing Quality – Learn how you can improve your swing quality by focusing on the plane, connection, and rotation.

Time to Contact is the elapsed time between the start of the downswing and impact. The start of the downswing uses an advanced algorithm to detect when functional forward Bat Speed is initiated and is not triggered by bat waggle early in the swing.

Vertical Bat Angle – is the angle of the bat with respect to horizontal at the moment of impact. Vertical Bat Angle is measured in degrees and provides the location of the barrel of the bat relative to the knob of the bat at impact. The vertical Bat Angle will be zero when the barrel of the bat and the knob are parallel to the ground. Vertical Bat Angle will be negative when the barrel of the bat is below the knob of the bat at impact.
