WAR (Wins Above Replacement)

Wins Above Replacement (WAR) is a statistical measure used in baseball to estimate a player's overall contribution to their team. It compares a player to a "replacement-level" player—a theoretical baseline representing a readily available, modestly skilled player. WAR calculates how many additional wins a player provides over this baseline, considering offense, defense, and other factors. Essentially, it quantifies a player's value in helping their team win games, with higher WAR indicating greater contribution. It's a useful tool for evaluating player performance in a single, comprehensive number.
