The American Coco Gauff, number 11 in the world, defeated the Japanese Naomi Osaka, winner of two Grand Slam titles, this Thursday by a double 6-4, and will be the rival of the Spanish Paula Badosa in the quarterfinals of the WTA tournament of San Jose (California, USA).
The 18-year-old Gauff needed an hour and 29 minutes to beat an Osaka who had seven match points canceled and rallied from 5-1 down in the second set to 4-5 before succumbing.
The young American tied the balance at 2-2 in the clashes with Osaka, against whom she had won at the 2020 Australian Open and lost twice, at the 2019 US Open and at Cincinnati 2019.
Gauff will meet Badosa, the second favorite, in the quarterfinals, in what will be the third meeting between the two.
Badosa beat her at the 2021 Indian Wells tournament, when she was champion, while Gauff triumphed this year in Indian Wells.
The Spanish debuted this Wednesday with a hard-fought victory in the third set against the American Elizabeth Mandlik.
The big surprise of the day was given by the American Shelby Rogers, who eliminated the Greek María Sakkari, number 3 in the world and first favorite, by winning 6-1 and 6-3.
Rogers, number 45, had eliminated Canadian Bianca Andreescu in the previous round and will face American Amanda Anisimova in the quarterfinals.
She had to suffer the Belarusian Aryna Sabalenka, number 6 in the world, who needed two hours and 36 minutes to beat the American Caroline Dolehide, number 168, 5-7, 6-1 and 7-5.
Her rival in the quarterfinals will be the Russian Daria Kasatkina, seventh favorite.
In the other match of the day, the Russian Veronika Kudermetova won 6-2 and 7-5 against the American Claire Liu and met the Tunisian Ons Jabeur, third favorite, in the quarterfinals.
