Nick Kyrgios’ return to the Australian Open is over after he and Thanasi Kokkinakis stopped playing while trailing in the second set of their first-round doubles.

Nick Kyrgios dropped a bomb at the Australian Open this week, revealing he can’t see himself playing men’s singles at Melbourne Park again.

Alex de Minaur, the world No. 8, and Nick Kyrgios, who is back after a two-year battle with knee and wrist injuries, are the headliners for their country at Melbourne Park. Kyrgios emceed the night session on John Cain Arena Monday, before De Minaur headlines Rod Laver Arena, the pantheon of Australian tennis Tuesday night.
