NEW YORK -- Everything felt better for Naomi Osaka once she returned to the U.S. Open.
The knee injury that forced her to retire during her last match no longer is so painful.
When she comes back to Flushing Meadows, she's a champion.
And in many ways, she's home.
"Yeah, I mean, I feel like I have a familiarity," Osaka said Friday. "That's not because I won last year. It's because I have been kind of hitting on these courts since I was a kid. I used to train here."
Osaka, the No. 1 seed for the tournament that begins Monday, has put that night behind her. She declined Friday to discuss her relationship with Williams, who subsequently apologized to Osaka.
Before ending that break, Osaka wrote a lengthy social media post in which she said she'd had some of the worst months of her life and probably hadn't had fun playing tennis since Australia. Things have since changed, she said.
"I took, like, a break sort of and kind of relaxed my mind and realized that you have to have fun doing what you love," Osaka said. "For me, I love tennis. Sometimes I feel like I don't, but I wake up every morning and if I don't play, I feel like I kind of have done nothing during the day."
She went on to reach the quarterfinals in both events since, but had to stop playing in the third set of her match against Sofia Kenin in the Western & Southern Open because of discomfort in her left knee. She wouldn't specify the nature of the injury, but said she's able to play more lately and is healing well.
And like the knee pain, the frustrations with tennis will eventually lessen as well.
She can rely on her comfort in New York and her confidence on its courts, unlike some players. Wimbledon champion Simona Halep has been knocked out in the first round the last two years and has acknowledged that the bright lights and the big city aren't exactly her scene.
She's working on it, going out to restaurants in the city and spending time in Central Park, in hopes that the noise in the arena won't be so jarring once she takes the court.
"I try to adjust myself as much as possible to this atmosphere. It's loud and it's different. Many people around," Halep said. "I like it, but being a spectator. Being a player, it's a little bit tougher for me, but year by year I'm getting better. So I have to work to improve more."
Osaka doesn't have to worry about that, having lived in the city for around five years when she was younger. She made it to the third round in 2016 and '17 before her breakthrough last September, and that has her thinking the next few weeks will be better than her previous few months.
"I'm not sure if it's because the last couple of months have been kind of turbulent, but definitely I feel really comfortable and I know that, despite everything, I play well here every year," Osaka said. "So I'm not too worried about that."
