The world number ones dominated the fifth day of the Australian Open, both through to the next round in straight sets.
Angelique Kerber defeated Czech Republic’s Kristyna Pliskova (6-0 6-4) and will face Coco Vandeweghe in the next round.
The American had earlier defeated Canada’s Eugenie Bouchard in three sets (6-4 3-6 7-5).
Andy Murray also had a straight-sets victory over the USA’s Sam Querry (6-4 6-2 6-4).
The 29-year-old, hoping to win the title after finishing runner-up five times, will now face Germany’s Mischa Zverev.
With the Novak Djokovic’s surprise second-round exit from the tournament, Murray is the clear favourite to win the Australian Open.
But he says he’s trying to focus on his own game rather than the eventual outcome.
Former world number one Roger Federer had another successful night on the court, beating Czech Tomas Berdych in straight sets (6-2 6-4 6-4).
Federer is looking to win a record 18 grand slam titles.
Svetlana Kuznetsova was also a winner on day five in a match that lasted three hours and 36 minutes.
The Russian eighth seed defeated Serbia’s Jelana Jankovic in three sets (6-4 5-7 9-7), saying she faced tough competition.
Stan Wawrinka had a slow start in his contest against Victor Troicki, but overcame the Serbian in four sets (4-6 6-4 7-6 7-6).
Wawrinka says he was glad the match didn’t go to the fifth set.
Number 12 seed Jo-Wilfried Tsonga was tested at times against American Jack Sock, but came out the victor at four sets (7-6 5-7 7-6 6-3).
Tsonga was able to break Sock early in the fourth set and went to a 3-0 lead.
At the end of the three and a half hours, the Frenchman came out the victor.
Tsonga’s opponent will be Great Britain’s Dan Evans, who in a tightly fought contest, defeated Bernard Tomic (7-5 7-6 7-6).
While it was a straight sets victory for the Brit, the match was a very close one; the final two sets lasting more than two hours.
Evans has made global headlines for a reason other than his on-court performances this week: he was dropped by his sponsors Nike and has been turning out in a plain white shirt he bought for 20 dollars.
But Evans, who says his shirts have started to shrink a little, wants to focus on his upcoming match.
It was also bad news for Australian Ashleigh Barty, who was knocked out of the Australian Open by Germany’s Mona Barthel (6-4 3-6 6-3).
Barty had already made her best major run by reaching the third round in a grand slam, and says she wans’t overly disappointed with her loss.
Meanwhile Venus Williams also had little to worry about on day five, easing past China’s Ying-Ying Duan in straight sets (6-1 6-0).
On day six of the Australian Open, Serena Williams will face American Nicole Gibbs, Australia’s Daria Gavrilova will take on Swiss Timea Bacsinszky and Karoline Pliskova will take on Latvia’s Jelena Oslapenko.
In the men’s contests, Alexander Zverev will face Rafael Nadal, Richard Gasquet will take on Grigor Dimitrov, Dominic Thiem will play Benoit Paire and Gael Monfils will face Philipp Kohlschreiber.
