Wins Above Replacement (WAR) is one of the the hallmark statistics available at FanGraphs and to match its prominence on the site, we’ve updated and expanded our Library entry on WAR. This week, you’ll notice more information in our basic WAR primer and a detailed page on how to calculate WAR for position players.

We’ll be updating the pitcher specific WAR page in the next couple of weeks and there is a blog post that walks you through a complete example of the position player WAR calculation. Look for it in the FanGraphs Library.

Feel free to ask questions in the comments, come to our weekly FanGraphs Q&A chats (Wednesdays at 3pm), or get in touch with me on Twitter @NeilWeinberg44 if you want to learn more.
