A fan was removed from the stands after he repeatedly heckled Canada's Bianca Andreescu during a 2-6, 6-3, 7-6 (5) loss to Marta Kostyuk of Ukraine in the first round of the Citi DC Open on Monday.
In the third set, the fan yelled 'out' when Andreescu missed several serves. The Canadian at one point turned toward him with her hands outstretched and yelled "shut up."
The umpire eventually radioed to security to have the fan escorted out.
Hours after the match, Andreescu posted a tweet that appeared to reference the incident.
Andreescu, currently 44th in the WTA rankings, came into the match as the underdog with Kostyuk ranked 34th.
The 23-year-old from Mississauga, Ont., lost despite winning 51.7 per cent of the points, largely thanks to a dominant first set.
It was Andreescu's first match of the hard-court season, having last played in a third-round loss to world No. 5 Ons Jabeur at Wimbledon before taking some time off.
Leylah Fernandez of Laval, Que., plays her first-round match in D.C. on Tuesday against American Bernarda Pera after making it through qualification.
Andreescu's attention now turns to Montreal for the National Bank Open — a tournament she won in 2019 as a precursor to winning the U.S. Open.
Her first-round match in Montreal is set for next Tuesday night.
