Coco Gauff had a special guest in attendance as she progressed to the China Open quarter-finals.

Fellow Grand Slam champ Naomi Osaka withdrew from their showdown with a back injury with the scores level at a set apiece.

Gauff is hitting form to close out the season

Gauff earned plaudits after her win for carrying Osaka’s bag off the court in a touching gesture.

She will face Ukrainian qualifier Yuliia Starodubtseva tomorrow for a place in the last four.

Olympic table tennis star Lily Zhang shared a video of Gauff serving against Osaka taken from the stands to her Instagram stories.

“my olympic roomie ,” wrote Gauff as she reposted the clip.

“roomies supporting roomies (but I lost too fast in china smash oops),” replied Zhang, who lost to Nayeong Kim in the China Smash tournament – also being held in Beijing.

Gauff reached the third round of the Olympics in what has been a tough year for the 2023 US Open Champion.

She split with legendary coach Brad Gilbert last month and is starting to hit her stride – moving to world No. 6.

“It was a good match up to this point,” Gauff said after her win.

“I wish Naomi a speedy recovery. Nobody wants to win a match like this, especially at one set all.”

Osaka recently returned to the top 60 after taking a break from tennis to give birth to daughter Shai last year.

“Hi everyone, I just wanted to say I’m extremely thankful and happy to have played in Beijing,” the 26-year-old said after pulling out.

“That being said I feel like I owe little backstory about today.

“So I locked my back up during practice earlier and honestly wasn’t sure if I could even play but I just wanted to try.

“Unfortunately things just got progressively worse during the match.

“Totally worth it though.”
