Iga Swiatek is enjoying a birthday week to remember – or perhaps one to forget.
The world number one turned 21 on Tuesday, between the 32nd and 33rd matches of a remarkable winning streak.
Having won five consecutive tournaments heading into the French Open, there was plenty for Swiatek to celebrate even before her big day.
So perhaps she can be forgiven for losing track of her age in the moments after her latest win against Jessica Pegula on Wednesday.
Having carried out her on-court media duties, Swiatek wrote a message on one of the Roland Garros cameras with the hashtag "#22".
"No, wait," the 21-year-old said just as she prepared to step away, covering her face with embarrassment. "I forgot how old I am!"
A failed attempt to wipe off the incorrect number resulted in Swiatek instead crossing out her message and scribbling "#21" next to it – far more untidy than any display she has turned in at Roland Garros.
