Career WAR stands for career wins above replacement, which is a statistic used in baseball to determine a player’s overall value to their team over the course of their career. This metric takes into account not only the player’s offensive and defensive contributions, but also factors in their position and the average performance of replacement-level players, or those who could be easily replaced with a minor league player or bench player. In essence, it is a way to measure a player’s impact on their team beyond just individual statistics.
