In professional tennis tournaments, a wild card refers to a tournament entry awarded to a player at the discretion of the organizers. They are usually awarded to players from the home and/or sponsoring country, promising young players, players that are likely to draw a large crowd, have won the tournament earlier or players who were once ranked higher and are attempting a comeback. Some Grand Slam tournaments swap wild cards, like Australian Open, French Open, and US Open.
