In tennis, a junior is a player 18 and under who is still legally protected by a parent or guardian.
Players on the main adult tour who are under 18 must have documents signed by a parent or guardian.
These players, however, are still eligible to play in junior tournaments.
The International Tennis Federation (ITF) conducts a junior tour that allows juniors to establish a world ranking and an Association of Tennis Professionals (ATP) or Women's Tennis Association (WTA) ranking.
Most juniors who enter the international circuit do so by progressing through ITF, Satellite, Future, and Challenger tournaments before entering the main circuit.
The latter three circuits also have adults competing in them.
Some juniors, however, such as Australian Lleyton Hewitt and Frenchman Gaël Monfils, have catapulted directly from the junior tour to the ATP tour by dominating the junior scene or by taking advantage of opportunities given to them to participate in professional tournaments.
