Incoming world number one, Rafael Nadal has been knocked out of the Cincinnati Masters by Australian, Nick Kyrgios.

22-year-old Kyrgios, who is currently world number 23, defeated Nadal in straight sets, 6-2 7-5 in the quarter finals on Friday to perfectly position himself for a US Open place.

Speaking shortly after the game, Kyrgios explained: “In the last couple of months I had a rollercoaster of scenes,”

Ever since Davis Cup, had such a big high. Obviously my grandpa passed away. Had some off-court issues. My head’s been all over the place.”

“I have just been going through a load of shit, sorry for cussing, but a load of stuff that’s distracted me from just trying to play some tennis, and hopefully I’m just trying to get on the right track again.”

The pair then paid tribute to the victims of Thursday’s attack in Barcelona, an incident Rafael Nadal described as “a tragedy”.

“[It’s] a tragedy, the feeling that you are not safe, so that’s terrible. So just very sad. I’m very, very sorry about what happened to all the victims, all the families, friends.”

“[This] is the moment to be together like a country and all being together, we go through these kind of things.” the Spaniard added.

Kyrgios will now square up against David Ferrer in the semi-finals on Sunday.
