Four-time major winner Naomi Osaka returned to action for the first time since May with a 6-4 3-6 6-1 win over Zheng Qinwen at

the Silicon Valley Classic on Tuesday, setting up a mouth-watering clash against teenage American Coco Gauff. 

Japan’s Osaka suffered a left Achilles injury in the lead-up to the French Open, where she lost in the opening round before pulling out of Wimbledon.

My best friends are from here. So I’ve been to the campus and been to the class, on the side. I kind of feel like a local, Osaka, who has currently slipped down to 41 in the rankings, said on court.

It’s good to be back playing, I haven’t played since May. I didn’t realize that but somebody told me.

“What’s always impressed me about Coco is her mentality,” Osaka, 24, said. “When I was her age, I would find myself getting frustrated

and I would show it. I just think it’s really cool how she’s able to stay really neutral all the time.
