The third round continues on day six of the Australian Open, featuring a difficult match between home contender and number one seed Ash Barty and Ekaterina Alexandrova, as well as a Briton in action as Cameron Norrie comes up against Rafael Nadal, who could now be considered favourite ahead of the injured Novak Djokovic.
We take a look at some of the best matches to look out for at Melbourne Park.

Top matches

All eyes will turn to Nadal, with the fourth round one match away for the Spanish second seed. The 34-year-old has not won the Australian Open for over a decade, his only win coming in 2009. This could be one of Nadal's best chances to bring that drought to an end given the injury struggles of Djokovic and the absence of Roger Federer.
Standing in his way is Norrie, with the Briton through after beating British number one Dan Evans in his first-round match, and while he has plenty of experience, one would expect Nadal to qualify for the last 16 with relative ease.
The match-up won't start until 8am UK time so there's a chance for audiences at home to enjoy it on Saturday morning, in the UK and Spain.

Potential upset

Barty remains the favourite for the tournament as the world number one, but she faces more problems than just Alexandrova. The Russian is a dangerous player in her own right, but the Australian has withdrawn from her doubles obligations as a result of a desire to manage a thigh strain.
Given the depth of talent in the women's game and the eerie atmosphere in an empty arena tomorrow, there is plenty of scope for an upset.
