SaberSQL is a tool to scrape baseball data from various sources and import it into a MySQL database.

Project description

SaberSQL

SaberSQL is a software tool to help scrape data on MLB games from Retrosheet (dating back to 1903) and BaseballSavant, as well as information on players, umpires, and managers (via the Chadwick Baseball Bureau Register). This data can then be imported to a MySQL database, allowing you to do customized queries on over a century of data.

Installation

Requirements

For SaberSQL to work, you must have already installed MySQL Community Server and Chadwick. MySQL is straightforward to install, and there is an excellent guide to install Chadwick here.

Install SaberSQL

To install:

pip3 install sabersql

Usage

To download and import all data to your database, simply use the command:

sabersql [path] -u [username] -p [password] -a [address] -s [schema]

where:

  • path is the directory on your computer where downloaded data should be stored (as of May 2019, all of the data is about 18GB total)
  • username is the user of the MySQL database
  • password is the user's password to the MySQL database
  • address is the network address of the MySQL database
  • schema is the name of the schema to be used (the schema should already exist, without any tables in it)
Optional Arguments
  • --download - only download the data from the web without importing it (the MySQL database information can then be omitted)

  • --import - only import the data (assumes data has already been downloaded)

  • -y [year] - only download and/or import a specific year's data

  • --retrosheet - only download and/or import Retrosheet data

  • --statcast - only download and/or import BaseballSavant data

  • --people - only download and/or import player, umpire, and manager data

  • --undo - undoes the command instead

Notes

  • Data will not be re-downloaded or re-imported if a command is run multiple times. Additionally, a process will resume from where it left off if restarted.
  • These processes are not fast. It will take many hours to download and import all data.

Schema

The structure of the database is five tables: person, pitch, event, game, and sub.

person

Each entry in this table represents someone who was a player, umpire, and/or manager.

pitch

Each entry in this table represents a pitch recorded by BaseballSavant. Descriptions of each field can be found here.

event

Each entry in this table represents an event that Chadwick processed from Retrosheet data. Descriptions of each field can be found here.

game

Each entry in this table represents a game that Chadwick processed from Retrosheet data. Descriptions of each field can be found here.

sub

Each entry in this table represents a substitution in a game that Chadwick processed from Retrosheet data. Descriptions of each field can be found here.
