WAR 2.01: Renaming ndWAR to afWAR

Posted by admin on May 4, 2012

The change from oWAR and dWAR to ndWAR and dWAR is confusing folks, so I'm making an additional change.

afWAR => Average-Fielding-WAR. The player's WAR if they were a league average fielder, or what you should use if you trust no fielding metrics.
dWAR => Defensive WAR thanks to fielding and position.

afWAR = batting + baserunning + DP's + replacement + position
dWAR = fielding + position

(NOTE POSITION IS IN BOTH OF THEM!)

afWAR + dWAR does not equal WAR as you'll be double counting the position adjustment. And on a team level you shouldn't be using WAR anyway to determine what your team is good or bad at.

I'll start adding version numbers as I make tweaks to the system. This one changes no numbers, so it really is just a naming convention.

Baseball-Reference.com WAR Explained - Baseball-Reference.com

As many have noticed, we have not been updating the 2012 WAR data in-season. The reason for this is that we have been working on a major upgrade to our WAR framework. The link above gives a very detailed rundown including: how to compute each part of our WAR formula, our reasoning on making the changes, downloads for historical WAR data, charts of the various constants and factors we use, and a chart of differences between the new B-R WAR, the old B-R WAR and FanGraphs WAR.

2012 B-R Daily Updates to Start April 4th

Posted by admin on March 27, 2012

Due to a combination of poor planning on my end and some snafus with data we are provided with, Baseball-Reference will begin updating daily with the Marlins/Cardinals tilt on April 4th.

Updating the site for a new season is always a harrowing experience given the multitude of interconnected moving parts. We are continually simplifying the process, but between the SABR Conference two weeks ago, the NLB launch, a couple of new servers we have coming online and my dawdling we aren't going to be ready to update the Mariners and A's games this week. I apologize to our users who want to see that data ASAP, but we'll make sure we are ready to go next week.

Thank you for your patience.
