US Open: Karen Khachanov Downs Nick Kyrgios To Set Up Casper Ruud Duel In Semi-Finals

Karen Khachanov set-up a US Open semi-final duel with Casper Ruud on Tuesday when he battled past "devastated" Nick Kyrgios in a big-hitting five-setter, shattering the Australian crowd-pleaser's dreams of a maiden Grand Slam title. Russian 27th seed Khachanov triumphed 7-5, 4-6, 7-5, 6-7 (3/7), 6-4 over the Wimbledon runner-up to make the last-four at a major for the first time. Earlier Tuesday, Norwegian fifth seed Ruud defeated Italy's Matteo Berrettini 6-1, 6-4, 7-6 (7/4) to make his second Slam semi-final of 2022 having finished runner-up to Rafael Nadal at the French Open.

Khachanov fired 30 aces and a total of 63 winners past Kyrgios.

The Russian said he had "nothing to lose" when he faces Ruud on Friday.

"I would like to win it," said Khachanov who lost to the Norwegian on clay in Rome in 2020 in their only previous meeting.

"But as deep as you go the expectations rise up. I did the step forward, I made my first semi-final and I think I have nothing to lose.

"I just want to go for it and be ready for the next match and hopefully it will be a good one."

Kyrgios, who had knocked out defending champion Daniil Medvedev in the last-16, hit 31 aces in his 75 winners.

"I'm devastated. It's heart-breaking for me and everyone," said Kyrgios.

"I feel like I have let so many people down."
