The Australian Open order of play for the middle Sunday is highlighted by the clash between world number one Iga Swiatek and Wimbledon champion Elena Rybakina.
Swiatek is also the reigning winner of the French Open and the US Open – so the winners of the last three grand slams will face each other in the third round.
Elsewhere, Coco Gauff takes on Jelena Ostapenko, while Stefanos Tsitsipas takes on Jannik Sinner in the main match at Rod Laver Arena.
Felix Auger-Aliassime will try to reach the quarterfinals against the talented young Czech Jiri Lehecka, who defeated Cameron Norrie in the previous round.
Here’s everything you need to know.
