SAN JOSE ( Associated Press) – Coco Gauff defeated four-time major champion Naomi Osaka 6-4, 6-4 on Thursday night to reach the quarterfinals of the Mubadala Silicon Valley Classic.
6 seed Gauff held all his serve in the opening set and ended the 45-minute session with three aces. Osaka committed the first double fault of the match at the start of the second set and Gauff took the advantage to lead 2–1. Gauff quickly took a 5–1 double-break lead and took a 40–0 lead, before Osaka saved four match points and used her first ace to turn 5–2.
Osaka then broke Gauff for the first time in the match and went 5–4 with five straight points to complete the 40–0 deficit. But Gauff capped it off with an irresponsible serve on his eighth match point.
“The most proud thing was how I mentally reacted,” Gauff said. “I could have easily folded in those two double-faults and the match points that I lost. But I kept telling myself ‘one more point, another chance’ and then the music helped on the bench. I was trying to sing along to the song to take me out of the match.”
Gauff’s win saw Osaka win the series two-two. Gauff will face number two seed Paula Badosa on Friday.
The other winners in San Jose were Shelby Rogers and No. 4 seed Aryna Sabalenka.
Rogers defeated top seed Maria Sakkari 6-1, 6-3 to reach the quarterfinals for the third time this season. She beat 2018 finalist and 2019 semifinalist Sakkari for the third time in San Jose, with an early-round victory against 2019 US Open champion Bianca Andreescu.
Sabalenka went down 5-3 in the third set to beat Caroline Dolehide 5-7, 6-1, 7-5. Sabalenka went on to face Russia’s No. 7 seed Daria Kasatkina, overcoming 20 double faults in the match.
Friday’s event in a hard-court US Open tune-up includes Wimbledon finalist Ons Jabur, who will take on Veronika Kudermatova.
