Top 10 duo roll on
Earlier on Monday, Daniil Medvedev and Hubert Hurkacz halted the unexpected runs of world No.69 Nuno Borges and wild card Arthur Cazaux.
2021-22 finalist Medvedev keeps rising through the gears this fortnight, chalking up a 6-3, 7-6(4), 5-7, 6-1 win over Borges.
"I'm ready. Hopefully I can show it on the tennis court. We can talk forever who is ready, who is favourite. You need to win," said a confident Medvedev, who will need to be wary with a 2-3 record over the net from Hurkacz.
"Hubi, tough opponent for me for sure. It's tough to return his serve. By number of aces, he was number one. Maybe actually the best server last year. That's going to be the key - I need to stay strong on my serve. Going to prepare well mentally tomorrow."
Hurkacz became the first Polish man ever to achieve a singles quarter-final berth in Melbourne, ending the inspired run of Cazaux 7-6(6), 7-6(3), 6-4.
"Making it to the quarter-finals, it's nice, but obviously we're hungry for more," maintained the No.9 seed. "Definitely proud of my performance and the team performance.
"Daniil is amazing competitor for so many years. He's been at the top. He was No.1 in the world. He won a Grand Slam. It's going to be a fun match."
