After reaching the peak of the sport in Melbourne, Osaka split with her coach, Sascha Bajin. Around the same time, she and her family were sued by a former childhood coach, who is seeking a percentage of her earnings. Her results have plateaued. She has a middling 13-7 record since becoming No. 1 and dropped to No. 2 in late June.

Though her record on clay and grass has never been as strong as it is on hardcourts, she was still deeply disappointed with a third-round exit at the French Open and the early loss at Wimbledon.

Osaka’s social media post on Wednesday was her first significant public statement since Wimbledon.

“Having this time to reflect and think (from losing in the 1st round lololol), I’ve learned a lot about myself and I feel like I grew so much as a person in this past year(s),” she wrote. “So I’m really excited what the future looks like on and off the court.”

Osaka wrote a similar post last year after a loss in Cincinnati. She said at the time, “I haven’t been feeling the ball right and it’s thrown me off a lot to the point where I started getting really frustrated and depressed during my practices.”

She had won the biggest title of her young career on the hardcourts of Indian Wells, Calif., in March 2018, and said she “had a lot of pressure entering the hardcourt swing because I felt a lot of expectation on me from Indian Wells and I didn’t feel like the underdog anymore, (which is a totally new feeling for me).”

She finished last year’s message on an optimistic note, heralding future successes: “I finally felt that fun feeling playing tennis” and signed off, “Update finished, see you in NY.”

There in New York, she was seen winning the U.S. Open.
