Furious Nick Kyrgios shouts, hits board, destroys racquet in rage during Australian Open doubles semi-final

It may come as no surprise, but Nick Kyrgios was not entirely calm and measured during his Australian Open doubles semi-final alongside Thanasi Kokkinakis. The Australian duo, who have been taking Melbourne Park by storm as wild cards in the doubles, clinched an emotional and memorable victory over Marcel Granollers and Horacio Zeballos in straight sets to reach the showpiece on Saturday night.

Ad/> 'Special K', as they are now known, had to battle ferociously at times to get past the doughty Granollers and Zeballos and eventually sealed a 7-6(4) 6-4 win in front of a raucous crowd inside Rod Laver Arena.

The 26-year-old also had moments where he lost his composure in a big way, even with his good friend and compatriot alongside him to calm things down at times. At 4-3 up in the second set, having won the first, Kyrgios got hugely frustrated with the umpire over the net cord sensor with Granollers and Zeballos having forced break points on his serve.

The Canberra star then proceeded to hit the backboard with his hand very hard in frustration to release some of the anger and tension that he was clearly feeling in the moment. Later in the same game, after his opponents had clinched what could have been a crucial break of serve, Kyrgios violently smashed his racquet on the ground and bent the frame quite considerably as Kokkinakis watched on.
