# Relative Hand Position - Towards Pitcher

> Distance along the axis towards the pitcher (+) or away (-) between mid-shoulders and the average of the two wrists at the foot contact event.

## Technical Details

* **Variable Type:** Discrete Metric
* **Data Type:** Float
* **Units:** raw: m, display: in
* **Column Name:** `relative_hand_position_towards_pitcher`
* **Aggregation:** mean
* **Precision:** 1
* **Measurement:** Distance from mid-shoulders to average wrist position
* **Direction:** Negative values (-) indicate the wrists are further from the pitcher than the neck (mid shoulders)
* **Timing:** At foot contact event
* **Typical Range:** -8.7 – -4.2 in
* **Optimal Direction:** Middle — moderate values are optimal

## Description

Relative hand position towards pitcher measures the forward-backward position of the hands relative to the shoulders at foot contact, indicating hand placement and swing setup.

## Normative Ranges

Percentile distributions by competition level from the 2026 Q1 dataset; the optimal range spans the 25th–75th percentiles.

| Population         | Optimal Range (25th–75th) |  10th |  25th | 50th | 75th | 90th |
