Russia's Dinara Safina hailed her "best ever tennis" as she swept past compatriot Svetlana Kuznetsova to win the Toray Pan Pacific Open final in straight sets on Sunday.

Safina followed up her semifinal demolition of Nadia Petrova with another awesome display to beat Kuznetsova 6-1, 6-3 and move up two places in the world rankings to No. 3.

After a difficult first match against Estonia's Kaia Kanepi this week, Safina hit top gear to win her fourth title of the year, and the 22-year-old believes she showed the form of her life to the crowd at Tokyo's Ariake Colosseum.
