MELBOURNE, Australia -- It's time for the eighth installment of the riveting, intergenerational rivalry between Novak Djokovic and Carlos Alcaraz. This one, though, will be the first at the Australian Open — and the first in the quarterfinals of a tournament; each of the others came in either a semifinal or final.

Novak Djokovic and Carlos Alcaraz will square off again in a Grand Slam after both stars won their fourth-round matches Sunday at the Australian Open.

Novak Djokovic will take on Carlos Alcaraz in a blockbuster quarter-final at the Australian Open on Tuesday. Alcaraz benefited from Jack Draper’s retirement after two sets of their clash before Djokovic defeated Czech Jiri Lehecka 6-3 6-4 7-6 (4).

Carlos Alcaraz reached his 10th career Grand Slam quarterfinal, tied for the most by a men's player before his 22nd birthday, by advancing at the Australian Open when 15th-seeded Jack Draper stopped playing because of injury after dropping the first two sets Sunday.

Alexander Zverev has reached the Australian Open quarterfinals for the fourth time and will face Tommy Paul next
