Rafael Nadal Stunned by Australia's Nick Kyrgios at Cincinnati Open

Nick Kyrgios of Australia in action against David Ferrer of Spain during their semifinal match in the Western & Southern Open at the Linder Family Tennis Center in Mason, Ohio, USA, 19 August 2017.

Austrian third seed Thiem crashed out of the ATP 1000 tournament following his upset defeat against veteran Ferrer in Cincinnati.

She was set to face United States wildcard Sloane Stephens in the semi-finals early this morning (Singapore time), while Pliskova took on Spain's Garbine Muguruza.

Hsieh and partner Monica Niculescu of Romania defeated the Ukraine duo of Lyudmyla Kichenok and Lesia Tsurenko 6-2, 7-5 in the quarter-finals and then moved into the final with a 6-4, 7-6 (8/6) win over India's Sania Mirza and Peng Shuai of China.

Kyrgios capitulated with three double faults in the second set at 5-5 to hand Bulgarian Dimitrov a decisive break.

Ferrer and his former coach Javier Piles went out of their way in NY in 2013 to provide Kyrgios and his then coach Simon Rea with a pathway to becoming a better player.

"I know I won, but I'm sure she feels like it was a great match as well, because it was a tough battle and very hot out there". I certainly didn't serve great during the set. "I think we both played very well, especially in the third set".

"I played some pretty good points. I just haven't had that confidence in closing out big matches". And then I played a bad game. "Congrats to him. That's it".

Kyrgios admitted he found facing Ferrer tricky in his semi-final and hopes he can replicate the character he showed in edging past the Spaniard. "He serve, you know, (more) than 130 miles", said Ferrer, a 2014 W&S finalist.

Dimitrov has a 1-0 edge over Kyrgios, who will rise four places to No.17 in the rankings. Dimitrov needed only 52 minutes to beat Yuichi Sugita 6-2, 6-1.

Dimitrov who reached his first Masters 1000 final said after the game; "It's a good step".

"To be No. 1 after all the things I've been going through the last couple years is something unbelievable", Nadal said. "It's a good feeling". "Even if I would be second coming to the US Open, it's still better than I was past year".

Kyrgios had Nadal running to all corners of the court as he overpowered the Spaniard in the baseline rallies, before Nadal managed to hold serve to reduce arrears to 4-3. "I think all that brings me good memories and just a positive way of thinking when I come out there on the court".
