Garbine Muguruza was not impressed with how her fourth-round match at the US Open against Barbora Krejcikova ended, and spoke of her frustration afterwards.
Krejcikova, the 2021 French Open champion, eventually clinched a dramatic 6-3 7-6(4) victory that finished after 1am in New York, but Muguruza was left far from happy with some of her opponent's behaviour.
The drama began as the eighth seed took a medical timeout when 6-5 down in the second set to receive some treatment from the trainer for a diaphragm issue.

When the match resumed following the break, Krejcikova proceeded to win seven points in a row, leaving her opponent hugely frustrated.
Muguruza, the ninth seed, also appeared to be more and more angered by her opponent taking her time between points at the business end of the match, slowly walking over to her towel and gathering herself before serves.
Finally, at the end of the late-night contest, Krejcikova remained in her chair by the side of the court after her opponent had left the stadium, until she was eventually escorted away from the court with some assistance.
Two-time Grand Slam champion Muguruza told the Czech as they exchanged a lightning quick handshake at the net that her conduct was “so unprofessional” - and she elaborated further post-match with the media.

When questioned by a reporter that she seemed upset, Muguruza replied to leave no doubt that she was not overly happy with the 25 year old.
"Listen, I don't really want to talk about this," she said in her post-match press conference. "It's… I'll let you guys judge what you think about this.
"Well, I think, between players, you know a little bit how to behave in certain moments.
And, yeah, I wasn’t very happy at the end of the match.
Krejcikova responded: "Things started to get complicated. Garbine started to raise her level and I was expecting that.
"At the end I was really struggling and I feel really bad right now. I don't really know what happened but I couldn't breathe. I started to feel dizzy and the whole world was shaking.
"It has never happened to me before. I just gave my all at the end. It's tough because it was my first time on such a big court playing the night session and I was really having fun until then."

Krejcikova, previously a doubles specialist, is making her singles debut at Flushing Meadows and has now reached the quarter-finals, having followed up her triumph at Roland Garros by progressing to the fourth round at Wimbledon.
The Czech will next take on number two seed Aryna Sabalenka on Tuesday with a place in the semi-finals on the line for the duo.
