Nick Kyrgios in 'the most uncomfortable' situation after 'nightmare' US Open win

Nick Kyrgios called his US Open first-round victory over Thanasi Kokkinakis

'the most uncomfortable match in his career' as he came through in straight sets to progress at Flushing Meadows.

The doubles partners and great friends were forced to face off for the first time late on Monday evening.

Kyrgios and Kokkinakis shot to doubles stardom at the Australian Open earlier this year by winning the tournament.

Meeting for the first time as individual competitors

the former was considered a heavy favourite against the world no 70.

Despite powering all the way to the Wimbledon final last month, Kyrgios went into the US Open as the 23rd seed but many expect him to go on another barnstorming run.
