Aryna Sabalenka briefly halted her US Open match against Kamilla Rakhimova because of a strong smell of cannabis before cruising into the fourth round in New York.
Top seed Sabalenka raised the issue after going 3-0 up in the first set against Uzbekistan’s Rakhimova, telling umpire Eva Asderaki-Moore that “someone is smoking weed”.
The Belarusian asked the umpire to intervene “because it’s so strong”.
Asderaki-Moore spoke to an official on her radio and made a smoking gesture to someone behind her, before play continued.
Two-time defending champion Sabalenka went on to secure a confident 6-3 6-4 victory on Louis Armstrong Stadium as she chases a fifth Grand Slam singles title.
Sabalenka said afterwards she was not sure where the smell of cannabis was coming from but asked fans to be more mindful.
Smoking is not permitted on site at Flushing Meadows but the smell of cannabis sometimes wafts on to court from the nearby Corona Park.
It is legal to smoke it in New York for adults aged 21 and over.
“It’s a bit tricky to handle that smell while you’re trying to compete at your best,” Sabalenka said.
“I don’t know if it was coming from the crowd or was from the outside because the wind blows it into the stadium.
“I just hope they’re going to be a bit more aware of that stuff.”
Sabalenka is not the first player at this year’s US Open to complain about the smell of cannabis at Flushing Meadows.
Britain’s Katie Boulter previously said it was distracting, while Harriet Dart and Francesca Jones also noticed the smell.
In past years players including Novak Djokovic and Alexander Zverev have also complained.
