Sixth-seed Gauff held off four-time Grand Slam champion Osaka. The match lasted two sets with Gauff dominating in both. The No.6 seed held off all of Osaka’s serves in the opening set, ending the session with three aces.
“The most proud was how I responded mentally,” Gauff said.
“I could have easily folded in those couple of double-faults and match points that I lost. But I kept telling myself `Another point, another chance’ and then the music kind of helped on the bench. I was trying to sing along to the song to get me out of the match.”
The match marked Gauff’s 2nd win against Osaka, evening out their record to 2-2.
After the loss, Osaka said, “I lost the match today but I feel really confident in who I am.”
“I feel like the pressure doesn’t beat me. I am the pressure. I’m really happy with that.”
On Friday, Gauff will meet 2nd-seed Paula Badosa.
Sabalenka edged out Caroline Dolehide 5-7, 6-1, 7-5. She is next to meet Daria Kasatkina.
