An ex-tennis player from South America has told the BBC that match-fixing is commonplace and even some elite players are “a little bit dirty in some way”.
He also claimed fixing is not just limited to lower-ranked professionals and is “a secret that everybody knows”.
The player, who requested anonymity, said tennis authorities “know who is doing it” but are unwilling to stop it.
The Tennis Integrity Unit (TIU) said it rejects “any suggestion that evidence of match-fixing has been suppressed”.
“We invite the player behind the allegations to make contact with the TIU and to share the information he claims to have,” the TIU added in a statement.
The allegations come after a BBC and BuzzFeed News investigation revealed suspected illegal betting in tennis over the past decade.
In an exclusive interview with the BBC’s World Have Your Say team, the player, who featured in several tour matches last year and is now a coach, detailed how the fixers operate and the lengths they go to in order to remain undetected.
“This is like a secret on the tour that everybody knows, but we don’t talk about it,” said the player, whose identity is known by the BBC. “We just see it and keep working.”
