Russian Daria Kasatkina, who has beaten all four reigning Grand Slam champions in the past year, upset world No. 2 Caroline Wozniacki 6-4, 7-5 at the WTA Indian Wells event on Tuesday.
Kasatkina recorded her second straight win over Wozniacki, having also beaten the reigning Australian Open champ at the St. Petersburg tournament last month.
The 20-year-old Kasatkina improved to 11-6 on the WTA Tour season as she seeks to better her quarter-final appearance here in 2016.
Kasatkina hit one ace, won 54 percent of her first serves and broke Wozniacki’s serve six times in the one hour, 40 minute match.
