LONDON: Japanese fifth seed Kei Nishikori, who had been suffering from a rib injury in recent weeks, pulled out of his Wimbledon last 16 match against Marin Cilic, on Monday. Nishikori looked lost and consulted the trainer and doctor during the fourth round match and finally pulled out at 6-1, 5-1 down on Court Two. Croatian ninth seed Cilic now faces either seven-time champion Roger Federer or Steve Johnson of the United States in Wednesday’s quarter-finals.
