It was the first time the pair had met with Kyrgios running out with a 7-6 (11-9) 7-5 win.

The 21-year-old managed 25 aces and saved two set points in the first set tie-breaker.  

He has now beaten all of tennis’ ‘big four’.

Kyrgios will face Sam Querrey with Rafael Nadal taking on Marin Cilic in the other semi.
