MELBOURNE, Australia — One of them has operated with ruthless efficiency, the other has brought the drama. But Carlos Alcaraz and Novak Djokovic have performed the opposite roles en route to their hotly anticipated Australian Open quarterfinal, which will be played Tuesday January 21 in Melbourne.

Carlos Alcaraz has reached his 10th career Grand Slam quarterfinal, tied for the most by a man 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 of their fourth-round match.
