THE ALL ENGLAND CLUB, LONDON — There are only two players who have been able to knock Ben Shelton out of Grand Slams this year: Carlos Alcaraz and Jannik Sinner. That’s good news and bad for Shelton, who exited Wimbledon in the quarterfinals Wednesday afternoon as Sinner sent him home, 7-6 (2), 6-4, 6-4.

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.
