TOKYO: Olympic silver medallist Dinara Safina powered past Svetlana Kuznetsova in an all-Russian final on Sunday to win the Pan Pacific Open, her fourth title of the year.

Safina, the 22-year-old French Open finalist and world No 5, notched an easy 6-1, 6-3 victory over Kuznetsova, the 2004 US Open champion and world No 7, to take the title in her first-ever appearance in Tokyo.

"I'm just feeling great. I've been playing here the whole week my best tennis I've ever played. It's nice, because it's the first time I'm here in Tokyo. I could show my best tennis. I'm really happy this week," said Safina.
