Before you get started...
All data displayed on this website comes straight from the Gameday data published by MLB Advanced Media. I have made no modifications or corrections.
Open this tool in as many windows as you like, but you'll want to let each window finish loading before opening a new window. Pitch data is passed to each chart "live," so if you attempt to load two pages at once, the second page's data will populate any charts on the first page that have not yet loaded.
The chart images can not be hot-linked because of how the data is passed. You can, however, right click the charts and save them to your computer. They are generated as GIF images, so I recommend saving them as GIF images.
Parts of this site are still under construction. As I find time, I will be finishing construction piece by piece. If you would like to contact me, you can reach me through the contact form on my blog.
Current dataset includes the entire 2008 and 2009 seasons. 2007 may be added later.
