(VIDEO) Djokovic given controversial penalty for hindrance in Sinner Wimbledon semi-final clash

Novak Djokovic's semi-final clash at Wimbledon against Jannik Sinner nearly descended into chaos early on after the former was given a controversial penalty for hindrance.

The World No.2 saved multiple break points in his opening service game and then immediately broke the Italian to impose his dominance early on.

He eventually wrapped up the set but to begin the second, he was called for hindrance after he lets out a long grunt following a backhand down the line.

He dropped to his knees before protesting his innocence but it wasn't over turned. At the time he was 2-1 up in the second set.
