Eight players earned their place in the BNP Paribas Open quarterfinals by winning their fourth-round matches on Tuesday and top two seeds Naomi Osaka and Simona Halep are not among the winners.
The world No.1 Osaka won just four games against seed No.23 Belinda Bencic, while second-ranked Halep was conquered by world No.61 Marketa Vondrousova in three sets. Bencic’s quarterfinal opponent will be fifth seed Karolina Pliskova, who eliminated seed No.21 Anett Kontaveit in the fourth round, while Vondrousova will face sixth seed Elina Svitolina, who survived seed No.
