What does WO mean in tennis?
WO or walkover is a term commonly used in the sport of tennis. It is used when a player wins a match without having to play, usually because their opponent has failed to show up or has withdrawn due to an injury. A WO is also known as a forfeit or a retirement. The term walkover is derived from the phrase "walk over the court," which is what the victorious player must do to win the match. A walkover is not the same as a default, which is when a player is disqualified for not following the rules. A walkover is an uncontested victory for one player.
