Perth Scorchers are set to be dragged into an international match-fixing scandal, but WACA chief executive Christina Matthews is adamant that the attention is inadvertent and nothing to do with any illicit activity.
Perth won only one match during the controversial 2012 Champions League tour of South Africa, but that victory over the Auckland Aces has been identified as a potential target of an International Cricket Council investigation.
New Zealand batsman Lou Vincent, who has provided information to anti-corruption officials on "widespread fixing across cricket" involving matches in at least five countries, is understood to have pointed to that match in Pretoria as potentially fixed.
New Zealand chief executive David White confirmed Auckland matches at the tournament were under scrutiny.
Vincent played against the Scorchers in the game notable for brothers Shaun and Mitch Marsh being axed as the scapegoats for a drunken team dinner.
Perth won comfortably after Auckland's run chase was hindered by the stodgy opening stand involving Vincent, who scored just two in nine deliveries.
The opener defended seven consecutive balls then got out swinging wildly at Ryan Duffield.
Matthews said there had never been any suggestion that the match was linked to match- fixing.
"We don't know anything about it and no one has ever asked us about it," Matthews said. "As far as we are concerned it was a fair and even game."
Former Auckland captain Gareth Hopkins said he had never suspected any match in which his team was involved to be fixed.
Vincent is understood to have provided information about match-fixing as part of a plea bargain to avoid criminal prosecution.
