Australian Open junior champion Oliver Anderson has been charged with match-fixing in his native Australia.
The charges relate to a match at the Traralgon Challenger tournament in Victoria last October, according to a statement from Victoria Police.
Anderson, 18, beat Uzbekistan's Jurabek Karimov to claim the Australian Open boys' singles title in January 2016.
"Oliver is cooperating fully with authorities. He now awaits the legal process," said a family spokesman.
He will appear before magistrates on 2 March.
Anderson, who is from Brisbane and ranked 743rd in the world, was first named by the Age newspaper in Melbourne on Thursday.
A Victoria Police statement added: "Sporting Integrity Intelligence Unit detectives and bookmakers assisted with the investigation.
"The Queensland man was charged with engaging in conduct that corrupts a betting outcome."
In the match at the centre of the allegations, Anderson lost the first set against Harrison Lombe after being broken at 4-4 before going on to win the next two sets.
Anderson then lost to John-Patrick Smith in the second round of the second-tier event in Latrobe City.
Last year, a joint BBC/Buzzfeed investigation alleged that the Tennis Integrity Unit, the organisation responsible for policing the sport, failed to act on suspicions that 16 top-50 ranked players have been involved in match-fixing.
