After winning the first two sets and having Sinner in serious upset danger, Grigor Dimitrov had to retire due to injury in the third set. The 34-year-old from Bulgaria had battled injuries for much of his career, and he knew something was wrong with his pectoral muscle after a serve.

Jannik Sinner is through to the Wimbledon quarterfinals, though not in the way he wanted. Sinner lost the first two sets of his fourth-round match with Grigor Dimitrov on Monday before Dimitrov was forced to retire from the match after suffering an apparent pectoral injury.

It was a major reprieve for Sinner, the three-time grand slam winner who looked set to be on the end of a seismic shock in front of a stunned Centre Court. The Italian had slipped on the baseline in the opening game and took a medical timeout midway through the second set for treatment on his right wrist and elbow.
