THE ALL ENGLAND CLUB, LONDON — Novak Djokovic will get another crack at Jannik Sinner at a Grand Slam, after defeating Flavio Cobolli in four sets to reach a 14th Wimbledon semifinal.

It was the obvious question to ask Novak Djokovic after his Wimbledon semifinal loss to Jannik Sinner on Friday. "Novak, would you be sad if that was your last match on Centre Court?"

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.
