MELBOURNE:World number two Svetlana Kuznetsova was dumped from the Australian Open by Polish teenager Agneiszka Radwanska in the biggest upset yet on the women's side of the draw.
The second seed, who struggled with indifferent form in the early rounds, was unable to match 29th seed Radwanska's aggression and went down in straight sets 6-3, 6-4.
The 18-year-old Pole, ranked 28 in the world, said she was on a mission to avenge three losses to the former US Open champion Kuznetsova last year.
"I played against her a few times, always losing, so I said 'no more'," she said. "It's very exciting, I'm very happy."
Radwanska said she set out to give the powerfully-built Kuznetsova the runaround.
"I tried to make her play left-right, left-right, run her round the court," she said.
Kuznetsova was chasing the game from the outset, falling behind 3-0 as Radwanska shot out of the blocks.
She never recovered her momentum and Radwanska served out the set at 6-3 after 35 minutes.
The shellshocked Russian managed to rally early in the second set and scored her own service break to go up 3-0 but she could not pull together her game with Radwanska contantly snapping at her heels.
The Pole broke back and Kuznetsova faded again, in the end surrendering her Australian Open dream meekly after 77 minutres as Radwanska served out the match.
