We’ve Added NPB Data to the Site!

by
April 24, 2025

We now have NPB data available on FanGraphs! It can found on the player pages and the leaderboards.

A few notes on NPB data:

  • All NPB data is provided by Sports Info Solutions and is available going back to 2018.
  • We update NPB (and KBO) data around 11:30 ET each night with the previous days games.
  • wRC+, ERA-, and FIP-, are park adjusted using five-year park factors.

Speaking of park adjustments, MiLB and KBO wRC+, ERA-, and FIP- are now also park adjusted using five-year park factors. You can read more about how our park factors are calculated here.

Please be aware that the additional leagues we’ve added to the site this offseason (NPB and Division-I college data) do not come to us without expense. All of our data is licensed from various data providers or sourced in-house. While this increases the site’s cost of doing business, it allows us to provide a consistent data product to our readers without interruptions.

If you enjoy our work and the numerous new features that we’ve added to the site this offseason, please consider becoming a FanGraphs Member. It keeps the lights on, and allows us to continue to add new features and voices to FanGraphs.

You Aren't a FanGraphs Member
It looks like you aren't yet a FanGraphs Member (or aren't logged in). We aren't mad, just disappointed.
We get it. You want to read this article. But before we let you get back to it, we'd like to point out a few of the good reasons why you should become a Member.
1. Ad Free viewing! We won't bug you with this ad, or any other.
2. Unlimited articles! Non-Members only get to read 10 free articles a month. Members never get cut off.
3. Dark mode and Classic mode!
4. Custom player page dashboards! Choose the player cards you want, in the order you want them.
5. One-click data exports! Export our projections and leaderboards for your personal projects.
6. Remove the photos on the home page! (Honestly, this doesn't sound so great to us, but some people wanted it, and we like to give our Members what they want.)
7. Even more Steamer projections! We have handedness, percentile, and context neutral projections available for Members only.
8. Get FanGraphs Walk-Off, a customized year end review! Find out exactly how you used FanGraphs this year, and how that compares to other Members. Don't be a victim of FOMO.
9. A weekly mailbag column, exclusively for Members.
10. Help support FanGraphs and our entire staff! Our Members provide us with critical resources to improve the site and deliver new features!
We hope you'll consider a Membership today, for yourself or as a gift! And we realize this has been an awfully long sales pitch, so we've also removed all the other ads in this article. We didn't want to overdo it.

I’m certain that this would delight me if I knew what NPB means.

I hope someone see this question to a day olds post, but could you clarify if the use of MiLB park factors goes back in time? I know Dan mentioned in his chat that he has minor league park factors going back to 199x or something. It would be great to know if the wRC+ is park adjusted in a given interval of years so that we would know when we are making historical apples to apples comparisons. Thanks.

We are using park adjustments for all years of MiLB data on the site (2006-current).
