Petti: Introducing the interactive spray chart tool

From SABR member Bill Petti at FanGraphs on November 4, 2013:

I’ve been working on an interactive tool that allows you to create spray charts using Game Day data from the past two years for a few weeks now. I’ve always loved the Katron Batted Ball tool, and it’s been a great resource of mine for years. However, I wanted to put something together that was a bit more interactive, allowed for more filtering, and made side-by-side comparisons easier.

Our writers here at FanGraphs have been kind enough to play around with it and offer suggestions. After some tweaks I am ready to officially release the tool into the wild so that anyone can use it.


This is not HITf/x data (boy, I wish), but is taken directly from the Game Day PITCHf/x feed. That means you need to use and interpret this data with a bit of a grain of salt, as the location data is based on where the ball was fielded, not on where it hit the ground.
