First Sinner, Djokovic and Draper. Now Carlos Alcaraz has also withdrawn from Toronto's ATP tournament.
The competition, which starts next week, comes too close to Wimbledon according to Alcaraz who says he needs to rest.
World number one Jannik Sinner, who defeated Alcaraz in the Wimbledon final, withdrew a few days ago with reference to an elbow injury. Fifth-ranked Jack Draper and sixth-ranked Novak Djokovic have also withdrawn from the competition with injury concerns.
