The 28-year-old Russian, as well as his Georgian colleague Nikoloz Basilashvili, came under suspicion because of the Belarusian coach Yegor Yatsyk, who is preparing both players.

According to the German publication ZDF, Yatsyk offered money to the players for them to play the match with the required result..

The source cites the words of an anonymous Eastern European coach. He said that Yatsyk has been involved in match-fixing for many years, working mainly in the Russian and Eastern European markets..

" He always has money with him. When he is on the Tour, he pays attention to young tennis players who have problems, financial, psychological, on which he can easily make money, "

Five matches involving Karatsev could be fixed at once.

Abnormally large bets were placed on each of them, which aroused suspicion.

The International Tennis Federation (ITF) has launched an investigation into the fourth racket of Russia. If found guilty, Karatsev faces a lifetime disqualification, a fine of up to $250,000, and even prison..

In the updated ATP ranking, Karatsev is on the 40th line, Basilashvili is on the 25th. The Russian is the silver medalist of the 2020 Olympics in the mixed doubles.
