Kyrgios was angry with crowd in semi final Miami Open 2017

In a match between the most popular man in tennis and the most misunderstood, the fans played a significant role in pushing Federer over the line. And not just by lifting his spirits.

The first set was forced into a tie-breaker with Kyrgios appearing to go into his shell a little as the crowd cheered and urged the Fed-Express on.

Early in the tie-break, Kyrgios started to lose his cool as the crowd became restless causing the young volatile star to take a bite out of ticket buyers.

As he was lining up his serve, the 12th seed paused and looked to the side of the court.

The umpire could sense the 21-year-old was starting to let his frustrations cloud his judgement and asked the crowd to settle down.

Kyrgios begins to bounce the ball again before he serves, yet stops again taking a look at the edge of the court in disgust as a crowd member screams ‘come on!’.

The umpire interjects again asking a fan to turn off their radio resulting in the Australian asking the crowd to ‘shut up!’, with the umpire again pleading with Kyrgios to let him take care of the situation.

The crowd starts playing up, laughing at the exchange before giving Kyrgios a collective boo over the incident.

Kyrgios promptly shanked the shot well wide and then started remonstrating with the fan in furious fashion. “Oh my god, shut up!” he shouted. “Shut the f--- up! What the f--- are you doing?”
