Nick Kyrgios retired after playing three sets of his third-round US Open encounter against. Ilya Marchenko.
The Australian star, who is ranked No. 16 in the world retired due to a hip injury he had been nursing since the US Open began.
Kyrgios was behind by two sets to one, 4-6, 6-4, 6-1 before ending the match against his Ukrainian opponent.
”My hip was bothering me my first two matches and I got through,” Kyrgios said. ”I guess it was just a matter of time.”
He dealt with a hip problem earlier this season.
”I’ve got to take more time and be more diligent with (the) gym and everything, so this doesn’t happen to me,” said the 21-year-old Australian.
Marchenko did not hide his excitement about what he’s now achieved, exclaiming to the crowd during an on-court interview: ”It’s round of 16! Oh, my God!”
He will face two-time major champion and No. 3 seed Stan Wawrinka next.
”I played him this year already. He killed me completely, outplayed me in everything,” said Marchenko, who lost 6-3, 6-2 to Wawrinka on a hard court at Indian Wells, California, in March.
