After failing to defend her Australian Open title, Sofia Kenin's trip to Melbourne got even worse on Sunday when the American suffered a shock defeat by unranked local teenager Olivia Gadecki in the second round of the Phillip Island Trophy.

Three days earlier, Kenin had admitted to struggling under the pressure of defending her maiden Grand Slam title as she was beaten 6-3 6-2 by Estonian Kaia Kanepi on Margaret Court Arena.

Gadecki saved two break points in the final game before serving out for the biggest win of her fledgling career.
