Novak Djokovic has made it clear that he is not saying goodbye to Wimbledon with a loss to Jannik Sinner in the semifinals.

Fast forward to his semifinal against Jannik Sinner, and something pretty unexpected happened on court: Sinner actually apologized to Novak about that fall when the two met at the net following match point. And of course, in true Djokovic fashion, he had the classiest response that’s got everyone talking about his sportsmanship.

Djokovic looked a step slow in Friday’s 6-3, 6-3, 6-4 defeat to Sinner after a painful fall in his quarterfinal win over Flavio Cobolli.
