The upsets continued for the women at the Australian Open as third-seeded Maria Sharapova and eighth-seeded Jelena Jankovic both lost their fourth round matches.
Sharapova was upset by No. 20 Dominika Cibulkova 3-6, 6-4, 6-1 while Jankovic fell to No. 11 Simona Halep of Romania 6-4, 2-6, 6-0. Cibulkova and Halep will face each other in the quarterfinals.
Meanwhile defending champion Victoria Azarenka advanced safely to the quarterfinals – and a showdown with No. 5 Agniezska Radwanska. Azarenka defeated American Sloane Stephens (the last American remaining in the singles draw – both men and women) 6-3, 6-2. Radwanska also won in straight sets over 20-year old Garbine Muguruza of Spain.
Men’s number one Rafael Nadal was made to work over three hours before grinding out a 7-6(3), 7-5, 7-6(3) win over Japanese Kei Nishikori. He next faces No. 22 Grigor Dimitrov. The 22-year old is in his first Grand Slam quarterfinal (also the first Bulgarian to do so) after a four-set win over Roberto Bautista Agut – who defeated fifth-seeded Juan Martin del Potro in the second round.
In what was supposed to be a tight contest, No. 6 Roger Federer gave No. 10 Jo-Wilfried Tsonga a tennis lesson as the Swiss advanced to the quarterfinal with a 6-3, 7-5, 6-4 victory. Federer faces No. 4 Andy Murray in the quarterfinals. Murray defeated unranked Stephane Robert in four sets to reach his fifth straight Australian Open quarterfinal.
