Wimbledon champion Jannik Sinner, 24-time Grand Slam title winner Novak Djokovic and No. 5-ranked Jack Draper all have withdrawn from the Masters 1000 tournament in Toronto that starts in a week.

Goran Ivanisevic suggests beating Jannik Sinner has become a daunting task and Novak Djokovic dealing with an injury going into their Wimbledon semifinal made it basically impossible for the Serb to beat the world No. 1.

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.
