US Open: Federer, Djokovic both lose in semifinals

Kei Nishikori stunned world number one Novak Djokovic at the US Open to set the final against Marin Cilic who knocked out five-time champion Roger Federer.

Nishikori, seeded 10th, won 6-4 1-6 7-6 (7-4) 6-3 to become Japan's first Grand Slam singles finalist.

Cilic, seeded 14th, powered through 6-3 6-4 6-4 to move into his first Grand Slam final.

"This was an extraordinary double for the underdog. If Cilic's victory over Federer - who had shown signs of frailty in his narrow quarter-final win - did not come as a complete surprise, Nishikori's triumph defied logic.
"At the start of the third set, the Japanese wore the look of a man who wanted to go for a quiet lie down. Instead, with fuel levels running low after two consecutive five set matches, he went on the attack - thrillingly and brilliantly - and Djokovic couldn't respond in the way we are used to.
"Cilic, full of the belief instilled in him by coach Goran Ivanisevic, hit the ball cleanly and powerfully and - unlike Monfils - gave Federer no chance to launch a comeback at the end of an unforgettable day."
