Maria Sharapova is out of the Australian Open after a shock defeat to Slovakia's Dominika Cibulkova in round four.
The 2008 Champion lost 3-6 6-4 6-1 to the 24-year-old after leaving the court for a medical time out just before the final set, but the Slovakian closed the match in just two hours 12 minutes to set up her first Australian Open quarter-final tie with Simona Halep, after her 6-4 2-6 6-0 win over Jelena Jankovic.
Third seed Sharapova follows five-time champion Serena Williams out of the competition, after a back injury allowed Serbia's Ana Ivanovic to come back from a set down to qualify for the last eight with a 4-6 6-3 6-3 win.
This leaves second seed Victoria Azarenka as the highest ranked player left in the competition, after her 6-3 6-2 win over Sloane Stephens.
Yesterday's results saw 30th seed Eugenie Bouchard defeat Casey Dellacqua 6-7(5) 6-2 6-0, fourth seed Li Na defeated 22nd seed Ekaterina Makarova in straight sets 6-2 6-0, and 28th seed Flavia Pennetta defeated ninth seed Angelique Kerber 6-1, 4-6, 7-5.
Agnieszka Radwanska takes on Garbine Muguruza in the final women's fourth round match of the Australian Open later today (Monday).
