The Baseball Projection Project

The purpose of the Baseball Projection Project* is to harness the talent and the hard work of the the many amateur and professional baseball forecasters out there. These people, like myself, use a variety of formal and informal methods to do one thing: predict the performance of baseball players. Here at the Baseball Projection Project, I ask that you submit your projections so that history may judge your forecasting ability, and so we as a community can research ways to do it better.

If anyone wishes to use the data on this site to write an article for print or online consumption, please do two things: 1) let me know, and 2) cite appropriately. I'll link back to it on the left rail, below.

To submit a projection, request a link to your blog or article, or for any reason, please email me at:

larsonwd@gmail.com

or tweet at me here:

FAQs

Q: Who are you?
A: I'm Will Larson, and I'm a Ph. D. economist. I'm from Montana, live in DC, love to golf, and have fun with baseball stats in my spare time. My personal/professional website is at www.williamlarson.com.

Q: Why CSV files and not excel?
A: It's way easier to deal with large amounts of .csv data than .xls data.

Q: Why only R, HR, RBI, AVG, SB for hitters and W, SO, WHIP, and ERA for pitchers?
A: Many people are interested in modeling player statistics using structural models (using k/bb%, hr/fb%, babip, for some examples). If you want detailed data like this to do forecasting yourself, go to Fangraphs or Baseball Databank. My site is meant simply to be a place where you can find different forecasts of top-line numbers.
