In 2008 my brother asked me to look at this Pitch FX data that mlb was releasing. He showed me some people who had some scripts that downloaded it and put it into a mysql database. I edited the scripts to run throughout the year in under 30 minutes, and export the data for anyone to download. Below is the database updated daily in the season. If you have any issues please comment or email me.
During the season I use a scheduled task that runs 4 commands.
1. Download the Pitch f/x files from MLB.
2. Import the data from the files.
3. Update the database with the pitch count.
4. Extract and zip the files for download.
