“On the morning of his arrest, Grigor Sargsyan was still fixing matches. Four cellphones buzzed on his nightstand with calls and messages from around the world…. The information on his devices would provide a remarkable window into what has become the world’s most manipulated sport, according to betting regulators. Thousands of texts, gambling receipts and bank transfers laid out Sargsyan’s ascent in remarkable detail…”

That’s part one of a two-part story in which more than 181 tennis players are involved, and from more than 30 countries, fixing more than 375 professional tennis matches. The Washington Post reveals the years-long investigation that began when Belgium’s gambling commission tipped off their federal prosecutor’s office to “irregular wagers on obscure tennis matches played around the world.”

The breakthrough came with geolocation data on a cellphone, cross-referenced against the the names of people who’d recently flown to that country…

The bets were made in small towns in the Flemish countryside. The gamblers appeared to be acting on inside information; they consistently won even when they bet against steep odds… [Nicolas Borremans, a 45-year-old police investigator based in the Flanders region of Belgium] knew little about sports. He had never watched an entire tennis match. But even a cursory description of the case was enough for him to see how a gambling operation might be used to launder money…

Within a few months, he had traced the accounts of four men who had placed suspicious bets in Belgium, all Armenian immigrants. Their wagers were mostly small — a few hundred euros each — ostensibly to avoid scrutiny. Almost all of the bets were on low-level professional tennis tournaments, where players earned barely enough to pay for their travel. Borremans secured wiretaps on the gamblers’ phones, and a team of Armenian interpreters listened in. It became clear that the gamblers were working for someone. They received detailed instructions about which matches to bet on. They weren’t gambling just on the outcomes, but on specific scores for sets and games… Borremans added more gamblers to his diagram. “Money mules,” he called them. Eventually, he would uncover 1,671 accounts at gambling establishments across Europe. Many were registered by working-class Armenians: mechanics, a pizza deliveryman, a taxi driver.
While the tennis tour “has in recent months issued a raft of bans and suspensions,” the article points out that the scale of the gambler/tennis player network “has remained a secret until now, in part because the tour is still working on active investigations related to the operation.” (The professional tennis tour has its own investigation unit “formed in part because of pervasive allegations of match-fixing in the sport,” which assisted the Belgian police.)

The operation’s “maestro” had tried to evade investigators. (One French player received his payment in 21 separate transfers from Armenia.) The maestro also gave the tennis players anonymously-registered SIM cards for communication. But unfortunately, the article points out, every professional tennis player “signs a contract agreeing to hand their phones over to tennis investigators at any time if required.” Soon investigators were reading the mastermind’s text messages — and even wiretapping his phone calls to his mother.

His phone’s search history would later offer a glimpse into his life and concerns. Sargsyan scoured the internet for references to himself and his players (“maestro tennis,” “match fixing tennis hossam”); he did some broader research into his world (“tennis corruption,” “armenian mafia”); he searched for ways to spend his new fortune (“escort geneve,” “villa rent close port mallorca”) But, mostly, he searched for new bookmakers (“croatia betting shop,” “usa betting,” “mybet Australia”).
Caught in the investigation were Sebastian Rivera, the Chilean coach based in the United States, and Slovakian tennis player Dagmara Baskova (who says she was paid 10,000 euros for each thrown match). Another French player told investigators “Since 2015, I estimate that I have accepted to deliberately lose or manipulate the outcome of 20 to 30 matches for Maestro, both in singles and doubles.” Some tennis players infuriated the maestro by tipping off other gamblers about their plans to throw matches.

Leaving the courtroom for his own trial, the maestro gave this response to the Post reporter asking how he felt about the courtroom proceedings. “If the prosecutor knew what I know, there would be many more people on trial.” Later the maestro was sentenced to five years in prison for fraud, money laundering, and leading a criminal organization.
