Grigor Dimitrov led by two sets when he retired from his Wimbledon match against Jannik Sinner on Monday, with an injury costing him a potential upset against the world No 1.
Dimitrov held a 6-3 7-5 lead against Sinner in their fourth-round match on Centre Court, but at 2-2 in the third set, the Bulgarian clutched his chest and fell to the grass on his backside – possibly struggling with a pectoral issue.
