He sat down opposite my bench, it scared me a bit," Muchova's testimony about being watched by her ex-boyfriend in the US Open stands
Present in the third round of the US Open after a hard-fought battle won against Sorana Cirstea (7-6, 6-7, 6-4), Karolina Muchova experienced a delicate situation at the start of the match.
The Czech player, a two-time semi-finalist in New York, was seen making gestures toward the stands while she was trailing 4-1.
In remarks reported by the media Express, she explained being disturbed by the presence of her ex-boyfriend:
"This has nothing to do with tennis, so I don’t like to talk about it. But my ex-boyfriend, who sometimes shows up where he shouldn’t be and where I am, sat down opposite my bench. It scared me a bit, and I asked him if he could leave.
He left a little while later. I’m happy with how I handled the situation. I had trouble concentrating, but then I found my rhythm and was able to fight for every ball.
