Kyrgios also reached the quarter-final of his home tournament, the Australian Open, in 2015 but has only ever made it as far as the third round in the French Open and US Open, until this year.

He has also had success in men’s doubles, winning at the Australian Open earlier this year alongside countryman Thanasi Kokkinakis.
