Stanislas Wawrinka remains on course to retain his Australian Open title after the Swiss man marched into the final four after a straight-sets win over Japan’s Kei Nishikori in the quarter-finals.
The world number four has dropped just one set so far in the competition so far and faced no real threat from the Japanese man until the third set as he raced into a two set lead.
Nishikori saved five match points from 6-1 in the third and as he forced a tie-break but the defending champion saw off the challenge and advanced to the semi’s with a 6-3 6-4 7-6 (8/6) win.
There was also a comfortable victory for world number one Novak Djokoivic after he saw off Canada’s Milos Raonic, also in straight sets 7-6 6-4 6-2 to set up a semi with the reigning champions Wawrinka.
On the womens side, top seed Serena Williams powered into the semis after a straight sets win over 2014 runner-up Dominika Cibulkova. The Slovakian caused the 18-time grand slam singles winner no threat as Serena booked her spot in the semi-finals with a 6-2 6-2 victory.
However, there won’t be any Williams sister showdown as Venus lost out to promising young star Madison Keys.
The 19-year-old had taken the opening set in 29 minutes but fell 4-1 behind in the second, before leaving the court to receive treatment for an injury. The young American some how fought back winning the next three games before Williams broke back and kept her serve to take it to a decider.
Williams twice moved a break up in the third but Keys fought back and won the last three games to take the set and the match a 6-2 4-6 6-4 and book a semi-final with Venus’ sister, Serena.
