Wins Above Replacement or Wins Above Replacement Player, commonly abbreviated to WAR or WARP, is a non-standardized sabermetric baseball statistic developed to sum up the extent of "a player’s total contributions to their team". The WAR value recorded for a player is claimed to reflect the number of additional wins their team has amassed relative to the number of expected team wins if that player was substituted by a replacement level player: a player that may be brought to the team for minimal cost and effort.
