World No. 22 Daria Kasatkina announced she has tested positive for COVID-19. Kasatkina is isolating herself and she won't be able to defend her St. Petersburg title next week. "Hi everyone. I have some bad news. I arrived in St.
Petersburg and tested positive for COVID-19. Right now I'm in complete isolation and following all the protocols," Kasatkina said in a statement posted on her Twitter account. "St. Petersburg Ladies Trophy is one of my favorite tournaments.
It's a pity to miss it. But (the) most important (thing) is to take care of yourself and others."
Kasatkina made a good start to the year
Kasatkina made back-to-back semiifnals at the Melbourne Summer Set 2 and Sydney.
In Sydney, Kasatkina stunned former world No. 1 Garbine Muguruza 6-4 6-4. After the match, Kasatkina said it was her best ever start to the season. "I think this is the best start of my career ever," Kasatkina said after beating Muguruza "I think I never start the season that well.
To win always feels amazing. Doesn't matter if you are winning the matches right before a slam and you maybe feel you're tired - it doesn't matter, because better you win the matches than you lose first round, and then you go and you have one week to practice, but for what? You have been practicing the whole preseason.
"So the most important is the confidence, and you get it by winning matches. This is the most important, because at the end, OK, tiredness can affect of course, but the most important is to feel confidence while you're playing."
After beating Muguruza, Kasatkina lost to Paula Badosa in the Sydney semifinal. Kasatkina then made the third round at the Australian Open, before losing to Iga Swiatek. Hopefully Kasatkina will quickly recovered from COVID-19 and be able to resume her normal activities as soon as possible.
