Metrics

+----------------------------------+----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+ | Name | Definition | +----------------------------------+----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+ | 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. | +----------------------------------+----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+
