Nick Kyrgios reached his first Grand Slam singles semi-final with a straight-set success over Chile's Cristian Garin at Wimbledon.

Kyrgios won 6-4 6-3 7-6 (7-5) to become the first Australian man since 2005 to reach the last four at Wimbledon.

Having reached a second Wimbledon quarter-final eight years after his first, the 27-year-old put in a strong serving performance to advance.

He will face either Spanish second seed Rafael Nadal or American Taylor Fritz.

Kyrgios fell to his back, arms spread out, as a missed shot from Garin confirmed his place in the last four.

"I never thought I'd be in the semi-final of a Grand Slam," Kyrgios said.

"I thought that ship had sailed - that I may have wasted that window in my career."

The world number 40 is the lowest-ranked men's semi-finalist at SW19 since 2008, when 75th-ranked Marat Safin and 94th-ranked Rainer Schuettler advanced.

Garin, 26, had produced a superb comeback performance in the previous round to beat another Australian, Alex de Minaur, but could not keep out Kyrgios in the key moments.

The result came a day after it was confirmed Kyrgios will appear in court in Australia next month in relation to an allegation of common assault.
