Former world number one Caroline Wozniacki defeated top seed Sam Stosur to claim the Kremlin Cup title in a tough three-set match lasting two and a quarter hours in Moscow.
Both women had come through testing three-set battles yesterday and entered today's final with the Australian slightly holding the upper hand in past meetings, having won three of five.
However, it was the Dane who prevailed, winning 6-2 4-6 7-5 to add to the title she won in Seoul last month.
Stosur has not won a title since she was crowned US Open champion more than a year ago and was inconsistent, her four aces accompanied by seven double faults.
Neither did she have any success with her second serve making her reliant on her first and only six of 15 break points were converted.

In contrast Wozniacki was consistent if not spectacular with greater success on her serve as well as taking greater advantage of her break point opportunities.
Wozniacki said on Twitter: "Won in Moscow today! 20th tournament title:) #excited."
