hEV: Horizontal Exit Velocity

Python script that builds yearly hEV leaderboards for batters.

Requirements

• Python 3.X
• PostgreSQL
• Statcast data (which you can get using this script)

Installation

Download the repo using Code > Download ZIP, or clone the repo using git bash.

git clone https://github.com/jefnic23/hEV.git

Setup

Open a console inside the hEV directory and create a virtual enviroment.

python.exe -m venv venv

Activate the virtual environment.

venv\scripts\activate

Then install dependencies.

pip install -r requirements.txt

Usage

Once everything is setup and dependencies are installed, create a .env file in the root directory.

type NUL > .env

Open the file in a text editor and copy these five variables, then assign them the appropriate value (make sure to enter the values between the quotation marks).

USER=''
PSWD=''
HOST=''
PORT=''
NAME=''

Finally, run the script from the console.

python hev.py

The output is saved to the data directory in .xlsx format.

Since the script relies on Statcast data, only MLB seasons after 2015 are valid. The script will check the database for which seasons are available and generate a spreadsheet with tabs for each season.
