Who Invented Wins Above Replacement (WAR)?
Wins Above Replacement (WAR) is a metric used in baseball to estimate how many additional wins a player contributes to his team compared to a replacement-level player. The concept of WAR was first developed by Bill James in the 1980s. James's original WAR formula was based on a player's batting, fielding, and running abilities. Over the years, WAR has been refined and updated by various analysts, but James remains the father of the metric.
WAR is now used by all 30 Major League Baseball teams as well as by many sabermetricians. It is considered one of the most comprehensive and accurate ways to evaluate a player's overall performance.
