Second set was a great service performance from Halys, who faced just two breakpoints. That were match balls at the same time, but Frenchman managed to delay his elimination till another tiebreak. It was also a tight contest, decided with just one mini-break gained by Djokovic, who needed almost 2 hours to clinch his QF place. He will face Denis Shapovalov there, who defeated Roman Safiullin in straight sets.
The last QF pairing will consist Sebastian Korda and Jannik Sinner, who won their matches without a set loss as well. Korda remainded Roberto Bautista Agut in the defeated field, Sinner deprived Thanasi Kokkinakis of chances of defending his last year's Adelaide title.
Ons Jabeur advanced to the WTA 500 quarterfinal after two sets with Sorana Cirstea. Tunisian seed #1 fought a tight first set against Romanian with 2 breaks on each side and tie-break at the end. World number 2 found her level in second set though and did not face any single breakpoint then. The contest between Jelena Ostapenko and Irina Camelia Begu brought quite a surprise. The Latvian, who played superb match against Karolina Pliskova in R1 was absolutely nowhere near this level today. 42% points won on serve was absolutely a disaster performance from Ostapenko. Match has ended up with score 6-3 6-0 for Begu, who allowed her opponent to score just 6 points in second set.
