Nick Kyrgios And Childhood Friend Thanasi Kokkinakis Win Australian Open Men's Doubles

Nick Kyrgios and Thanasi Kokkinakis won the Australian Open men's doubles final, to wrap up an incredible day for Australian tennis at Melbourne Park.

Kyrgios is one of the most controversial athletes in the world, with the tennis star splitting opinion on his on and off court actions and antics.

Despite all the questions about him, on Saturday he finally shut some of his critics up when, against all the odds at the beginning of the tournament, he and fellow Australian Kokkinakis, who is a childhood friend, won the men's doubles at the year's first slam.

On Rod Laver Arena, in front of a raucus crowd, they defeated fellow Australian pair Matthew Ebden and Max Purcell 7-5, 6-4.

The victorious duo, who have become known as Special K, have been friends for a number of years, since playing on the junior tours together.

The pair received a wild card entry into the doubles tournament at this year's open and have really lit up the competition in a way most wouldn't have expected.

In the second round they defeated Mate Pavic and Nikola Mektic and then beat third seeds Marcel Granollers and Horacio Zeballos in the semi final, the fourth pair of seeds they beat on the way to the final.

Their win over their fellow unseeded Aussies means it's the second doubles even they've won in a slam as a twosome, having won the Boy's doubles at Wimbledon in 2013.
