In sports, the terms Cinderella, "Cinderella story", and Cinderella team are used to refer to situations in which competitors achieve far greater success than would reasonably have been expected. Cinderella stories tend to gain much media and fan attention as they move closer to the championship game at the end of the tournament. The term comes from Cinderella, a well-known European folk tale embodying a myth-element of unjust oppression/triumphant reward. The title character is a woman living in unfortunate circumstances that are suddenly changed to remarkable fortune. In a sporting context the term has been used at least since 1939, but came into widespread usage in 1950, when the Disney movie came out that year, and in reference to City College of New York, the unexpected winners of the NCAA Men's Basketball championship also that year. The term was used by Bill Murray in the 1980 hit movie Caddyshack where he pretends as the announcer to his own golf fantasy: "Cinderella story. Outta nowhere. A former greenskeeper, now, about to become the Masters champion."
Referring somewhat inaccurately to the plot details of the classic Cinderella story, the media will debate whether the given "Cinderella" team or player will "turn into a pumpkin", i.e. fail to win the prize and then return to its former obscurity. In the fairy tale, it was the carriage that turned into a pumpkin at midnight, not Cinderella herself. Another popular term is "strike midnight", when a Cinderella team does finally get beaten.
Prior to the widespread use of "Cinderella" in this way, the more common term for unexpected and dramatic success was "Miracle", as in the "Miracle Braves" of 1914, the "Miracle of Coogan's Bluff" in 1951, the "Miracle Mets" of 1969, and the "Miracle on Ice" in 1980.
Cinderella teams are also referred to as a surprise package or surprise packet, and their success would be termed a fairy-tale run. A related concept is the giant-killer, which refers to a lesser competitor who defeats a favorite, reflecting the story of David and Goliath.
