Grigor Dimitrov suffered Wimbledon heartbreak when he was on the verge of knocking out world number one Jannik Sinner.
The 34-year-old Bulgarian was two sets up and playing some inspired tennis when, at 2-2 in the third set, he clutched his chest after serving an ace.
Sinner rushed around the net to check on his opponent as he sat, in some distress, on the court.
The 19th seed was helped to his feet by two physios and went off to receive treatment, before returning a few minutes later to shake Sinner’s hand.
It was more dreadful luck for a popular player, who had to retire injured from matches in the last four grand slams, including against Daniil Medvedev here at the same stage last year.
Sinner, who helped Dimitrov pack his rackets away and carried his bag off court, said: “I don’t know what to say. He is an incredible player, I think we all saw this today.
“He’s been so unlucky in the past couple of years. An incredible player, a good friend also. Seeing him in this position, if there would be a chance he could play the next round he would deserve it.
“I hope he has a speedy recovery. I don’t take this as a win at all. This is just a very unfortunate moment to witness for all of us.
“In the last grand slams he struggled a lot. Seeing him again having this kind of injury is very, very tough. It’s very sad. We all wish him only the best, let’s have applause for him.”
