Novak Djokovic has warned world number one Jannik Sinner that he is ready to go the distance in their blockbuster Wimbledon semi-final on Friday.

Jannik Sinner sure didn’t play like someone dealing with an injured right elbow Wednesday, using terrific serving and his usual booming forehand to dismiss 10th-seeded Ben Shelton 7-6 (2),

Novak Djokovic clinched a spot in Wimbledon's semifinals following Wednesday's win over Flavio Cobolli (6-7, 6-2, 7-5, 6-4) despite a scary fall in the final game of the match. Djokovic slipped on the grass after a forehand attempt led to a return from Cobolli that hit the net cord and made Djokovic lean to his left.

Sinner stayed by the side of Dimitrov who shed tears while he received treatment and the Bulgarian eventually threw in the towel and walked off to a standing ovation from the Centre Court crowd.
