The revelation was made following investigations into multiple incidents of match-fixing that involved Hirs.
Now the International Tennis Integrity Agency (ITIA) has confirmed Hirs will face a life-long ban from tennis; the case was ruled on by Anti-Corruption Hearing Officer, Amani Khalifa.
The ruling means that from July 18, Hirs will be permanently prohibited from playing in or attending any tennis events that are authorised or sanctioned by the governing bodies of tennis.
As well as the ban, Hirs has also been fined $35,000.
The player has been found guilty of three match-fixing charges and has also breached three sections of the Tennis Anti-Corruption program.
The first section involves the outcome of matches, which says "no covered person shall, directly or indirectly, contrive or attempt to contrive the outcome or any other aspect of any event.”
Meanwhile, the second focuses on making an individual participate in a match, without trying their best to win the face-off.
D.1.e of the Anti-Corruption program says that “no covered person shall, directly or indirectly, solicit or facilitate any player to not use his or her best efforts in any event.”
Lastly, D.2.a states that a player should report match-fixing incidents to the ITIA “as soon as possible.”
It says that if a player is approached by someone who offers money to “influence the outcome or any other aspect of any event or provide Inside Information,” the agency should be alerted to the matter.
