Junior tennis refers to tennis matches where the participants are aged 18 and under. Eligibility to compete in International Tennis Federation Junior tournaments is not based on age, but year of birth: as a result, some players must move out of juniors soon after their 18th birthday, while others can play juniors until they are nearly 19. Some players who qualify as "junior tennis" players also play in main adult tours, though forms signed by their parent or guardian are required for this. Historically, some junior players will turn professional at the age of 16 like Andre Agassi or Pete Sampras.
