Naomi Osaka gets her 1st top-10 win in more than four years

A year ago, still on maternity leave and still unsure when she would play elite tennis again, Naomi Osaka visited the U.

S. Open to appear with Michael Phelps for a discussion about mental health.

While at the site, she sat in the stands to watch one of Coco Gauff's matches.

Osaka also already was thinking about being back on a court at Flushing Meadows, so much so that she was pondering what she might want to wear to compete. And there she was Tuesday at Louis Armstrong Stadium, overpowering No. 10 seed Jelena Ostapenko 6-3, 6-2 while decked out, from her visor to her dress to the bows on her back and attached to her shoes, in lime green the color of this "Brat summer, as it happens (IYKYK) " and playing very much like a two-time champion at the place and a former No. 1-ranked star.
