With both 18-year-old Andreescu and 19-year-old Vondrousova into the quarterfinals, it is the first time since 2009 two or more teenagers are in the final eight in Indian Wells.
In 2009, three teenagers reached the BNP Paribas Open quarterfinals -- that year, Caroline Wozniacki fell in that round while Anastasia Pavlyuchenkova and Victoria Azarenka advanced to the semifinals.
Despite her loss to Belinda Bencic in the fourth round on Tuesday, Naomi Osaka will retain her World No.1 ranking following Indian Wells?as?No.2 Simona Halep lost to Vondrousova at the same stage on the same day.
Svitolina's fourth-round win over Ashleigh Barty?on Tuesday became?the longest match of the 2019 WTA season to date (three hours and 12 minutes).
