Victoria Azarenka has won a showdown between the world's two top ranked players beating number one Serena Williams in three sets in the final of the Cincinnati Masters.
For two hours and 30 minutes, Azarenka and Williams engaged in a seesaw centre court battle before the second ranked Belarusian finally clinched the victory, winning a tiebreak 8-6 to stop the American from ticking one 'to do' item off her 'bucket list'.
In a career that has generated 54 singles titles, including 16 grand slams, Williams had won just about everything there is to win in her sport - but not Cincinnati, one of the WTA Tour's most prestigious tournaments.
Cincinnati will remain a hole on her resume for at least another year after Azarenka answered the challenge claiming just her third win in 15 tries against the 31-year-old American.
Both players now head to the US Open.
