Australian Open 2021 video - 'Worrying times' - Victoria Azarenka struggles to breathe on court
Former world number one Victoria Azarenka struggled to breathe on court late in the second set and had to have a medical timeout away from the court in what were described as "worrying times" by the Eurosport commentary team. She eventually returned as Jessica Pegula completed a straight-sets victory.

The two-time champion in Melbourne, in 2012 and 2013, eventually returned as Pegula was able to close out a 7-5 6-4 win, but the scenes were troubling nonetheless.
Eurosport expert Annabel Croft, on commentary at the time, reflected on Azarenka's struggles as she was taken away from the court.
"I don't think she's feeling well at all, her walk has got so slow. I don't think she is feeling well," Croft said.
She's breathing very heavily. I think she needs to go and sit down. I think she is feeling very faint, and it's not the first time we've seen this kind of thing in Australia.

"She is walking very slowly to that medical timeout and it would be a miracle if they get her back to full energy levels. She has just blown herself out."
Thankfully, Azarenka was able to return, but Pegula will now progress at the 31-year-old's expense. She spoke about her unhappiness with the situation after the match.
"I truly don't understand that rule of why, when somebody is sick, injured or whatever, they have to give their medical reason out in the world," she said in her post-match press conference.
"I think that should be changed, unless players do want to talk about that, then they can. But it shouldn't be a mandatory requirement for people to talk about their health issues. Even legally, doctors should not release any information.
"In terms of that, I feel like that should be a bit of a light on a new and adjusted rule that should be in place."
