Novak Djokovic will face American Sebastian Korda on Wednesday for a place in the semi-finals.

Carlos Alcaraz goes on to face either American 27th seed Sebastian Korda or South Korea's Kwon Soon-woo for a place in the last 16.

Karen Khachanov had already won the first two sets 7-6, 6-3 and had a 3-0 lead over USA's Sebastian Korda in the third set.
