Novak Djokovic Opens Semis After Food Poisoning.

Novak Djokovic was handed a walkover to the Madrid Open semi-finals for the second time in three years as quarter-final opponent Marin Cilic pulled out of the tournament due to food poisoning.

Ninth seed Cilic explained on Twitter that he had experienced a terrible night dealing with a case of food poisoning and would therefore be unable to face Djokovic for a 20th time on the ATP Tour.
