Camila Giorgi dropped just three games to upset third-seeded Sloane Stephens 6-0, 6-3 in the second round of the Toray Pan Pacific Open on Thursday.
The unseeded Italian, who reached the semifinals last year, beat the 2017 U.S. Open champion to set up a quarterfinal match against Belgian Elise Mertens.
“It was a good match for sure and I was able to play my game, show off my attacking style and be consistent,” Giorgi said.
“When I play I always focus on myself. I only made a few mistakes. That’s always been my way, ever since I was little, to attack, to go forward, to put the pressure on. This surface suits my game, too.”
Giorgi dropped her serve at 5-2 in the second set but she sealed the victory in the next game on her fourth match point.
Anastasia Pavlyuchenkova, who beat second-seeded Kiki Bertens 6-1, 7-5 to progress to the last eight, described her win as “super-tough.”
Wild card Misaki Doi will be Pavlyuchenkova’s opponent in the last eight after the Japanese upset seventh-seeded Donna Vekic 7-6 (5), 6-3.
Yulia Putintseva of Kazakhstan faces top-seeded Naomi Osaka of Japan in the quarterfinals after she defeated qualifier Varvara Flink 6-1, 6-1.
At the Korea Open in Seoul, third-seeded Karolina Muchova reached her third quarterfinal in her last four tournaments when she defeated qualifier Timea Babos 6-2, 6-3.
“I was trying to be more focused on myself, to play my game, and it worked out,” the Czech said. “I think I played pretty solid today, and it was enough to win the match.”
Muchova will next take on Australian qualifier Priscilla Hon, who edged fifth-seeded Ajla Tomljanovic in three sets, 6-3, 5-7, 6-1.
