The morning session of the Australian Open would witness the quarter-finals of the women's singles competition where Venus Williams would take on fellow American Madison Keys at the Rod Laver Arena.
The match would be then followed by Serena William's clash with DominikaCibulkova.
The top seed of the competition, Serena Williams has had to face two tough matches in her third and fourth round matches against Elina Svitolina and Garbiñe Muguruza respectively.
In both the matches, the American had to fight it out in three sets, which might prove to be taxing for Serena Williams, who needs to be on top of her game with the competition already having reached the business end.
Talking about her fourth round opponent, she said, ''Well, yeah, she made me play a lot better. I had to play the best match of the tournament or else I was going to be out.''
''I think she was just hitting winners like left and right. Every shot I hit, she basically hit a winner on. So I had to change my approach. I was hitting a little bit too much to her.''
It was her strong character, which helped her win the match eventually.
Serena, who faces Cibulkova knows that the Slovakian is a hard-hitter of a tennis ball and does not want to underestimate her.
"She (Cibulkova) is a really good player. I mean, to be her size, she hits so hard and she plays so well. She's just such a power, compact, great player."
"I just have to stay focused and not underestimate her. She actually almost beat me before. I want to make sure I come ready and prepared."
While her elder sister, Venus Williams will face the unseeded American tennis player, Madison Keys, who has defeated seeded players, prior to setting up a date with Venus Williams.
Keys would be trying to create a major upset by defeating Venus Williams, like the way she thrashed the Czech player, Petra Kvitová, in straight sets during the third round of the competition.
However, Venus Williams would be a confident player as well after defeating Agnieszka Radwańska in her last match in three sets.
''I just felt like in the third set I was trying to get back to the form that I was in the first set. I didn't do a lot wrong in that first game. It was just over hit some, missed an easy one that would have definitely helped my cause,'' said Venus Williams.
''It was frustrating but I stayed focused and I wanted to just continue playing like I did in the first game because it was really the right way to play.''
Venus Williams' quarter final clash against Madison Keys will be shown live on Sony Six and Sony Six HD, which has been scheduled for 11am local time (5:30am IST, 12am GMT, 7pm ET) start, which would be then followed by Serena Williams vs Dominika Cibulkova match.
