Indian Wells

Osaka in tears

After being broken in the first game, a fan shouted "Naomi, you suck" and Osaka could later be seen wiping away tears.

After the match, the event's 2018 champion addressed the crowd on center court, saying the incident reminded her of when Venus and Serena Williams were booed at the tournament in 2001.

"I've been heckled before and it didn't really bother me," Osaka said while holding back tears.

Novak Djokovic pulls out of Indian Wells and Miami Open over US coronavirus rules

Regulations require any non-US citizen to have a Covid vaccination before entering the country.

Serb Djokovic, 34, told the BBC last month that he had not been vaccinated.

The 20-time Grand Slam winner was included in the draw for both events, but has since posted on Twitter that he knew it was "unlikely" he could travel.

He is likely to make his return to the tour at the Monte Carlo Masters in April.

The Indian Wells draw will be less balanced following the late withdrawal of Djokovic, who was seeded second.
