MELBOURNE: Magdalena Rybarikova, the number 19th seed, fought back after a second-set wobble to reach the last 16 of the Australian Open on Friday.
The Slovakian beat Ukraine's Kateryna Bondarenko 7-5, 3-6, 6-1 in just over two hours on Margaret Court Arena.
She will face second seed Caroline Wozniacki or Dutch 30th seed Kiki Bertens for a place in the quarter-finals.
