While defending champion Carlos Alcaraz is yet to consistently find his top form at the tournament, Djokovic and Sinner have been dominant on the grass.
Fresh from his 100th win at Wimbledon on Saturday making him the third player to reach that landmark after Martina Navratilova and Roger Federer Djokovic faces Australian 11th seed Alex de Minaur.
