Tennis’ bad boy Nick Kyrgios was at it again on Thursday, smashing a racquet and flipping a finger at the crowd as he and partner Thanasi Kokkinakis ensured an all-Australian Melbourne Park men’s doubles final for the first time in 42 years. 

Kyrgios and Kokkinakis defeated third seeds Horacio Zeballos and Marcel Granollers 7-6, 6-4 to set up a final on Saturday against fellow Australians Matt Ebden and 
Max Purcell.
