Today, we’ve made some changes to Wins Above Replacement that completes the move from UZR to the full suite of Statcast equivalent metrics in FanGraphs WAR. This process began in 2022, when we replaced UZR’s range component with Statcast’s Fielding Runs Prevented, which is Outs Above Average (OAA) converted to runs above average. UZR will continue to be calculated on FanGraphs through the end of the 2025 season. Today’s changes are retroactive to the 2016 season.
Here is the complete list of what is included in this update:

We’ve added XBR (Statcast’s baserunning metric) to the Advanced section of our leaderboards. We have also added a new Statcast fielding section to our leaderboards, which include all of the additional metrics that have been added to WAR.
There are a handful of notable changes in WAR from the update, but almost all players’ WAR totals are within 1 WAR of their previous totals from 2016-2023. We’ve updated Legacy WAR (L-WAR) on the leaderboards if you’d like to see all the changes.
Here are the players whose WAR increased more than 1 WAR:
