US Open 2024 results: Naomi Osaka feels her ‘heart dies’ every time she loses after Karolina Muchova defeat

Osaka, who also won the Australian Open in 2019 and 2021, spoke before the US Open about not feeling “like I’m in my body” since her return from maternity leave.

She returned to the WTA Tour in January, but has not gone beyond the quarter-finals of any event – losing in the second round of Wimbledon and in the French Open this year, while she fell at the first hurdle at the Australian Open.

Despite the early exits, the four-time major winner said 2024 had been a “learning year”.

“It’s been a little difficult because obviously I can only gauge how I’m doing by results. Like, I feel faster. I feel better, but I lost in the second round. So it’s a little rough,” the former world number one said.

“But, also, it’s been fun playing a lot of tournaments. It’s been a commitment for sure, but I’ve been able to go to different cities that I’ve never been to.”
