Top matches

Look no further than John Cain Arena. Nick Kyrgios returns to his favourite court, in front of his home fans, looking to create more fireworks against third seed Dominic Thiem. They have only met each other once, six years ago, in a match which the Austrian won after a first set retirement from Kyrgios, so it is almost impossible to guess which way this one will go.
Serena Williams looks to continue her impressive start when she takes on Anastasia Potapova, while Novak Djokovic may find things tricky against big-serving American Taylor Fritz, after admitting the courts in Melbourne are playing fast this year.
Keep an eye as well on the all-Canadian clash between up-and-coming stars Denis Shapovalov and Felix Auger-Aliassime.

Potential upset

Second seed Simona Halep needed to come from behind several times to beat Aussie Ajla Tomljanovic in a guelling match on Wednesday and will hope to have recovered in time to face Russian 32nd seed Veronika Kudermetova.
Sixth seed Alexander Zverev is unpredictable at the best of times and faces Frenchman Adrian Mannarino, a player he’s beaten in all five meetings.
