Cincinnati: Victoria Azarenka toppled world No. 1 Serena Williams 2-6, 6-2, 7-6 (8/6) to claim the Cincinnati WTA title and establish herself as a contender for the US Open.
The two-and-a-half-hour epic featured multiple momentum shifts after Azarenka, the second seed from Belarus, began the afternoon with two double faults to lose the opening set in under 30 minutes.
She managed to steady herself and held on to beat the top-seeded Williams for only the third time in 15 matches. It was her second victory over the American this year, after a triumph in the final at Doha.
