He won all three tiebreakers in a charged night match atmosphere on Rod Laver Arena before a capacity home crowd willing their player on. "Playing against Nick is always tricky, two weeks I lost against him," Dimitrov said. "He was serving and playing unbelievable and he fought really hard. It's one of those matches that you have to be locked in and try to get any opportunity you have. "Even when I was serving for the match I felt that I was not finding my spots very well and I'm just glad I got through that match." Kyrgios double-faulted to lose the opening set tiebreaker and was broken in the seventh game of the second set leaving the moody Australian to shake his head cussing at the changeover and uttering "embarrassing."

But Dimitrov got a crucial service break in the eighth game of the fourth set when Kyrgios put a smash into the net to allow the Bulgarian to serve out for the match. The unpredictable Australian managed to break back to force a third tiebreaker. Again Dimitrov was too steady for Kyrgios, getting to three match points and winning it with a forehand pass.
