“It was kind of instinctive because when I shook her hand, I saw that she was kind of tearing up a little. Then it reminded me how young she was,” Osaka said. “I wanted her to have her head high, not walk off the court sad. I want her to, like, be aware that she’s accomplished so much and she’s still so young.”

The gesture was appreciated by everyone, with tennis fans and players praising the top seed for sporting spirit. Osaka herself tweeted that Gauff was a warrior while several WTA players hailed the Japanese star on social media.
