Kyrgios crashes out of US Open after right shoulder injury

New York: Australia's Nick Kyrgios, coming off his biggest career final, crashed out of the US Open on Wednesday after hurting his right shoulder in the third set of his opening match.

Kyrgios, the 14th seed who was the highest-ranked obstacle in Roger Federer's path to the quarterfinals, lost to 235th-ranked compatriot John Millman 6-3, 1-6, 6-4, 6-1.

"I know in the back of my mind Nick's shoulder deteriorated as the match went on," Millman said after his first US Open triumph. "It's a victory but slightly hollow.

"He's a team-mate. He's a great guy on and off the court. I feel for him. I really do."

Kyrgios endured an injury-nagged run-up to the US Open, hip pain knocking him out of Wimbledon and Queen's and a sore right shoulder forcing him out.
