The words match fixing have always conjured up one image: a cricket pitch.
Ahead of the opening matches at the Australian Open, the first grand slam of the year, Buzzfeed News and the BBC published details from secret files exposing widespread match-fixing by players at the top echelons of tennis.
The sport's governing bodies have, over the years, been warned about a core group of 16 players - all of whom have, at some point, ranked within the top 50 tennis players in the world and including Grand Slam winners - but none of whom have ever faced sanctions.
Eight of those, or 50%, are taking part in the Australian Open that began this Monday, 18 January.
Tennis authorities, comprising the men's ATP Tour, women's WTA tour and the international ITF "absolutely reject any suggestion that evidence of match fixing has been suppressed for any reason," says a statement on the Australian Open website.
Here's a quick primer to bring you up to speed:
Here's how BuzzFeed UK investigations editor Heidi Blake broke it down to ABC News 24:
From the BuzzFeed and BBC report, here's what was revealed in the Fixing Files:
Chris Kermode, chief executive of the Association of Tennis Professionals, strongly rejected these claims that the evidence was suppressed or inadequately investigated. He added that they would investigate any new information. "A year-long investigation into the Solpot match in 2007 found insufficient evidence. As the BuzzFeed report states itself, the investigators hit a brick wall and it just wasn't possible to determine who the guilty party was in relation to this match".
In 2009, tennis introduced a new anti-corruption code. After taking legal advice, authorities were told that they couldn't pursue previous corruption offences.
In 2011, world tennis issued its first ever life ban against a player. The player was Austrian Daniel Kollerer. He was banned for taking money to fix matches. Here's him admitting to the BBC about being offered money in Moscow, Chennai and Paris.
Three of the leading tennis players over the past decade, Serbian and current men's number one, Novak Djokovic, Swiss and multiple Grand Slam winner, Roger Federer and women's world number one Serena Williams spoke to the media about the scandal.
Djokovic said that he did not believe that match-fixing was a widespread problem in the world of tennis. He spoke about an incident in 2007 where it was alleged that he was offered $20,000 to throw away a first round match at the St Petersburg Open. That was a tournament he eventually didn't attend.
"I was not approached directly," he said. "Well . I was approached through people that were working with me at that time, that were with my team. Of course, we threw it away right away. It didn't even get to me, the guy that was trying to talk to me, he didn't even get to me directly. There was nothing out of it.
"When I'm playing, I can only answer for me. I play very hard, and every player I play seems to play hard," Williams told reporters following her opening-round victory against Camila Giorgi. She hadn't played a competitive match since losing at the US Open last year to Roberta Vinci.
"As an athlete, I do everything I can to be not only great, but historic. If that [match-fixing] is going on, I don't know about it. I'm kind of sometimes in a little bit of a bubble."
In his post-match interview after defeating Nikoloz Basilashvili, 6-2 6-1 6-2, Federer was asked about the match-fixing scandal.
"I don't know exactly how much new things came out, to be quite honest. I heard old names being dropped. That story was checked out. Clearly you got to take it super serious, you know, like they did back in the day. Since we have the Integrity Unit, it puts more pressure on them that a story like this broke again."
He went on to talk about betting in the sport. "Betting happens all across the world in all the sports. The players just need to know, we need to make sure the integrity of the game is always maintained because without that, I always would say, why do you come and watch this match tonight or any match, because you just don't know the outcome. As long as we don't know the outcome, the players, fans, it's going to be exciting. The moment that gets taken away, there's no point anymore to be in the stadium."
When asked about whether it was surprising that some of the players involved were Grand Slam singles and doubles players and even a Grand Slam champion, Federer had this to say,
"I would like to hear the name. I would love to hear names. Then at least it's concrete stuff and you can actually debate about it. Was it the player? Was it the support team? Who was it? Was it before? Was it a doubles player, a singles player? Which slam? It's so all over the place. It's nonsense to answer something that is pure speculation."
Over the course of the next few months, more details are bound to be told to the media either directly or leaked. Eventually, when more information comes out, it'll be even harder for the authorities to cover-up any such scandal. The onus is on the tennis authorities to take action and to do it soon.
