The muscle tear in his left leg forced Djokovic to retire after one set against Alexander Zverev, who will face top-seeded Jannik Sinner in the men’s final on Sunday. Djokovic was booed off the court, drawing admonishment from Zverev who called for fans to show some respect.

“I did everything I possibly can to manage the muscle tear that I had,” Djokovic said after the match. “Medications and the strap and the physio work helped to some extent today, [but] towards the end of that first set I just started feeling more and more pain. It was getting worse and worse. It was just too much to handle for me at the moment.

“I knew even if I won the first set it was going to be a huge uphill battle for me to stay physically fit enough to stay with him in the rallies for another, god knows, two, three, four hours. I don’t think I had that, unfortunately, today in the tank. Unfortunate ending, but I tried.”
