No longer in singles competition, Nick Kyrgios and Thanasi Kokkinakis have taken doubles seriously at the Australian Open, and they're making a serious run.
The two Australians are through to the quarterfinals, having knocked off top seeds Mate Pavic and Nikola Mektic—not to mention Pavic's angry trainer in the locker room—along the way.
It's even got the famously casual Kyrgios concentrating more on his preparation and training.
"This is actually our best run in a Grand Slam ever. So I think we've come with age and matured a little bit, I know I have definitely. I'm going to do everything I can tonight, get a good rest, recover, train. Listen to me," he said, jokingly.
"I like it," said Kokkinakis.
"I definitely think we've got a good shot at winning this," added Kyrgios.
