# Attack Angle

> Angle relative to forward horizontal that the bat sweet spot moves through in the frames leading up to ball contact. Postive value indicates the bat sweet spot is moving upwards at that angle, vice versa for negative.

## Technical Details

* **Variable Type:** Discrete Metric
* **Data Type:** Float
* **Units:** °
* **Column Name:** `attack_angle`
* **Aggregation:** mean
* **Precision:** 0
* **Optimal Direction:** Middle — moderate values are optimal
* **Measurement:** Bat position relative to the front of home plate
* **Time Period:** 3 frames before ball contact to 1 frame after ball contact
* **Typical Range:** -10° to +30°

## Description

Attack angle measures the vertical angle of the bat's path relative to horizontal, indicating whether the swing is level, uppercut, or chopping.

## Use Cases

* Bat path analysis
* Swing plane assessment
* Contact angle optimization
* Launch angle correlation
