# Swing Path Angle

> Plane angle of the bat swing path relative to horizontal in the 0.04 s leading up to ball contact. This measures the final approach angle of the bat.

## Technical Details

* **Variable Type:** Discrete Metric
* **Data Type:** Float
* **Units:** °
* **Column Name:** `swing_path_angle`
* **Aggregation:** mean
* **Precision:** 0
* **Optimal Direction:** Middle — moderate values are optimal
* **Measurement:** Vertical angle of swing path
* **Timing:** the 0.04 s leading up to ball contact
* **Typical Range:** 5° to 40°

## Description

Swing path angle measures the vertical angle of the bat's path in the final 0.04 seconds before ball contact, indicating the final approach angle and swing plane.

## Use Cases

* Final approach analysis
* Swing path assessment
* Bat position assessment
