Grigor Dimitrov retires with two-set lead over Jannik Sinner after suffering pectoral injury at Wimbledon

Grigor Dimitrov has endured more than his fair share of injuries.

Coming into Wimbledon, the Bulgarian had been forced to retire in his past four major appearances. On Monday, it increased to five in his most cruel ending yet.

Up two sets on world No. 1 Jannik Sinner inside Centre Court, Dimitrov pulled up clutching his right pectoral area after knifing a backhand volley to hold for 2-2 in the third set.

Sinner came over immediately to check on his opponent, who tried to laugh off the matter. But after being evaluated by medical staff in his chair, he decided he could not continue on. The official win for Sinner: 3-6, 5-7, 2-2 ret.

Dimitrov was given a standing ovation as tears emerged. Sinner advances to face Ben Shelton in the quarterfinals.

"I don't know what to say. He is an incredible player. We all saw this today," said Sinner. "He's been so unlucky in the past couple of years."

"I don't take this as a win at all. This is just a very unfortunate moment to witness for all of us."

The three-time major winner experienced his own injury scare early in the contest when he took a hard fall impacting his elbow right elbow that required a medical timeout. Speaking with press afterwards, Sinner shared, “I could feel it. So let's see. Tomorrow we are going to check to see how it is, and then we see.”

Last year, Sinner defeated Shelton in the round of 16 before falling to Daniil Medvedev over five sets.
