Victoria Azarenka stunned world number one Serena Williams 6-4, 6-4 on Sunday to capture her second Indian Wells crown and the 19th career singles title.
Azarenka blasted five aces while Williams was undone by 33 unforced errors and five double faults in the 88-minute match.
Azarenka has been a thorn in the side of Williams over the years and she became the first player to deny Williams a trophy on four occasions.
Heading into the contest Azarenka and Serena's sister, Venus, were the only players to have beaten Williams three times in finals.
Azarenka thwarted Williams' bid to become the first three-time winner of the Indian Wells women's title.
