The ASICS/Vaughan Junior and Cadet National Championships are considered the most prestigious youth wrestling events in the nation and have helped develop other numerous athletes who have gone on to win World and Olympic medals for the United States.    Greco-Roman competition will take place July 23-26, men's freestyle will compete July 27-30 and women's action will be held July 29-30. This will be the fourth year that a women's division will be featured at the Junior Nationals.     Up to 4,500 wrestlers from 49 different states will compete at the event. Two styles of wrestling will be competed at both the Cadet and Junior levels: Greco-Roman and freestyle. Women will compete in freestyle only.    The Junior Nationals include the nation's best athletes in grades 9-12 competing in both international styles.    The top 15- and 16-year old wrestlers in the United States will battle in freestyle and Greco-Roman for national titles and All-American honors at the Cadet National Championships.    In 2004, three records were set in Fargo, including the largest Junior National Championships, including all three divisions (2,320 participants), the largest Junior National Greco-Roman Championships (946 participants) and the largest Junior Girls National Championships (144 participants).
