Nick Kyrgios lost the first nine points of his Wimbledon quarter-final, spent the entire match in a sometimes demonstrative dialogue with himself and his team but ultimately delivered an assured winning display as he made his first ever grand slam semi-final.

With the spectre of an August court appearance hanging over him, the Australian advanced as he dismantled world number 43 Cristian Garin in straight sets, 6-4, 6-3, 7-6 (7/5).

The win makes him the first Australian male to make the semi-finals at The All England Club since Lleyton Hewitt in 2004.

Broken in the opening game of the match by his Chilean opponent, who had in the round before defeated Australian number one Alex De Minaur in five sets, Kyrgios only came to life on the 10th point of the match, when he broke Garin's early streak with a thunderous pair of aces.

From there, despite banter with his box, the Australian appeared locked in and ready for the challenges Garin was throwing at him.

In the sixth game of the match Kyrgios struck back.

A late flick of the wrist saw Kyrgios pass Garin crosscourt at full stretch and in ridiculous fashion to set up two break back points but the Chilean saved them, before Kyrgios broke on the third attempt as Garin dumped a regulation backhand into the net.

Still things were tense, and when Garin got a favourable net cord to set up two break points at 4-all, Kyrgios sarcastically applauded.

The Australian managed to save those and hold serve before he broke Garin to take the opening set as he let rip with a "let's go".

Kyrgios would continue the dialogue with himself throughout the second set but his focus remained as he reeled off eight straight points to hold serve and then break Garin for a 3-1 lead.

Garin pushed hard in the next game but again Kyrgios saved break points and the pair traded holds before the Australian broke again for a 5-2 lead and served out the second set two games later.

The third set saw Kyrgios battle his own demons as he screamed out "his level has gone up, and yours has gone down".

It was the case as the unforced errors for Kyrgios began to mount and the crowd began to get behind Garin, but serving at 2-3 Kyrgios staved off several break points and held for 3-all, as he reminded himself and his box to lift because Garin had just last round came back from two sets down to win.

The Australian, despite his level dropping off throughout the set and Garin looking increasingly dangerous, sent the third set to a tiebreak with a brilliant backhand half-volley.

He followed it up with a drop shot on the opening point as the pair traded mini-breaks throughout a tense tiebreak that was punctuated by forehand errors from both players.

Two mis-hit forehands from Kyrgios even gave Garin a 5-3 lead before the net cord sent a Garin pass attempt wide to see the breaker level at 5-5.

Kyrgios then stuck a pair of volleys to bring up match point as Garin netted a forehand.

The drama threatened on match point as a linesperson called a Kyrgios return out, before umpire James Keothavong overruled it but when Garin sent a backhand wide the Australian moved into the final four.
