baseballquery 0.0.2

A library to query MLB stats including on a game level

Baseball Query

It's a stathead replacement, plain and simple.

When you install this package and import it for the first time, it will download many GB of data from retrosheet. Eventually, it will be deleted, but you will get a total of 12 GB of data in the form of an hdf5 file. This is a lot of data, but it's necessary. This whole process (including calculating linear weights) can take upwards of an hour so start running this in the background once you install it before you use it.

Not implemented (as of when I finish this):

• Park factors
• Full game stats (saves, holds, shutouts, etc.) for pitchers. This one is probably important
• GB%, LD%, FB%, and PU% will deviate from fangraphs due to differences in data and it being quite subjective. Also, Fangraphs FB is more similar to FB+PU so that's what I used in HR/FB% calculations.
  • This probably is impossible to fix
