Naomi Osaka called for spectators at the US Open to respect tennis etiquette after social media influencers sparked debate by disrupting her first-round match.

Around 100 influencers and content creators have been accredited for this year’s tournament in New York, twice as many as last year, as organisers seek to reach new audiences.

Some players have questioned whether the push for online engagement has gone too far after crowd members were reprimanded for filming themselves and using a portable ring light while Osaka was serving during her first-round win over Anastasia Zakharova.

Two-time champion Osaka said the chair umpire had repeatedly called for quiet during her second-round victory over Katerina Siniakova on Thursday.

“I think obviously if you come to a sporting event, you have to respect the sport,” she said.

“I feel like it’s common courtesy to read up on the sport, especially the etiquette.”

The US Open introduced a policy of free fan movement in 2024, meaning spectators no longer have to wait to take their seats during changeovers.

Since Osaka’s opening match, there has been increased messaging on screens reminding people to refrain from any activity that could disrupt the game, including noise levels, flash photography and ring lights.

American 11th seed Jessica Pegula said some of the behaviour had been “disrespectful”.

“I can appreciate the influencers coming and showcasing the US Open experience,” she said.

“But I do think that it’s tough when you see videos when they’re taking pictures and using the selfie lights.

“People are down there trying to perform. It’s their career and their job. It seems a bit disrespectful.”

Arthur Ashe Stadium – the US Open’s main venue – is the biggest tennis stadium in the world, and matches are often accompanied by a buzz of noise.

World number four Coco Gauff welcomed the influx of new fans but said they should respect the traditions of tennis.

“I definitely think it’s cool to have a new demographic and I definitely think it helps grow the sport,” she said.

“But if you’re being invited to a red carpet, you wouldn’t show up in jeans.

“I think it’s just follow the etiquette of the sport.”

The United States Tennis Association said it wanted fans to have an “incredible time” while ensuring they did not interfere with the action.

“We are continually looking for ways to ensure fans in the stands know what is permitted and what is prohibited,” read a statement from the governing body.
