Hewitt, after going down fighting to David Ferrer at his farewell tournament, rounded on an anonymous online blog linking his name to the explosive report which has overshadowed the year's first Grand Slam.
The 34-year-old Australian called it a "joke" and an "absolute farce" that he should be linked with the match- fixing allegations outlined by the original BBC and BuzzFeed report, which did not reveal any names.
"I know my name's now been thrown into it. I don't think anyone here would think that I've done anything (like) corruption or match-fixing. It's just absurd.
"For anyone that tries to go any further with it, then good luck. Take me on with it. Yeah, it's disappointing. I think throwing my name out there with it makes the whole thing an absolute farce."
