Former world number one, Victoria Azarenka, took advantage of an error-prone display by Serena Williams to win her second BNP Paribas Open title at Indian Wells in California.
The 26-year-old Belarusian beat the American number one seed 6-4 6-4 under 90 minutes in front of a stunned crowd at the sun-baked Indian Wells tennis garden.
Azarenka broke the top-seeded American once in the opening set and twice in the second before wrapping up the victory.
Meanwhile, world number one Novak Djokovic produced a sublime form to clinch an unprecedented fifth men’s title at Indian Wells.
The Serb beat big-serving Canadian Milos Raonic with a 6-2 6-love in the men’s final.
The 28-year-old Serb broke his out-of-sorts opponent twice in the first set and three times in the second to wrap up victory in one hour 17 minutes on a blazing hot afternoon.
