Bat Tracking Data

BatSpeed (MPH)

Speed of the sweet spot just before impact.

BatAttackAngle (Degrees)

The angle of the bat's path, at impact, relative to horizontal.

A negative value represents swinging downward, a positive value upward.

BatImpactAngle (Degrees)

Top-down view of the angle of the bat at impact or closest point on missed swings normalized to the batter's hand.

0 represents perpendicular to the pitcher's mound, negative is before the bat reaches perpendicular, and positive is after the bat reaches perpendicular

BatAxialOffset (Inches)

Distance from the sweet spot to the impact point along the bat.

Negative is toward the handle of the bat, positive towards the head

BatRadialOffset (Inches)

Distance from the sweet spot to the impact point perpendicular to the bat.

Negative is below the center of the bat and positive is above.

BatBatterAbsXOffset (Feet)

Absolute value of the distance from the batter's center of mass to the contact point at impact in the horizontal dimension.

BatBatterAbsYOffset (Feet)

Distance from the batter's center of mass to the contact point at impact in the depth dimension.

Negative is toward the backstop, positive is toward the pitcher's mound.

BatVerticalAngle (Degrees)

The angle between the bat and an imaginary vertical line perpendicular to the ground

BatImpactDirection (Degrees)

Top-down view of the angle of the bat at impact or closest point on missed swings. 0 is toward the pitcher's mound, negative is toward third base, and positive is toward first base.
