MONTREAL -- Ukrainian tennis player Elina Svitolina spoke out about the deluge of hateful abuse she received online from frustrated gamblers after losing a match in Canada, including messages wishing her death and celebrating Russia killing her compatriots. Following her straight-sets loss to Naomi Osaka in the quarterfinals of the National Bank Open on Tuesday night, Svitolina posted screenshots of the messages to Instagram. The abuse was directed at her, while racial slurs also targeted her husband, French tennis player Gael Monfils, who is Black. "To all the bettors: I'm a mum before I'm an athlete," Svitolina wrote in her Instagram story. Boulter told the BBC in an interview that online abuse has become the norm and that she thinks many of the messages are sent by people who are placing bets on tennis matches.
