Andy Murray successfully tamed his dangerous first-round opponent Nick Kyrgios as the British number one sealed a controlled four-set victory at the US Open.
Kyrgios produced a typically explosive display under the lights of Arthur Ashe Stadium but Murray's touch and precision were a class above as the Briton won 7-5 6-3 4-6 6-1.
Murray has now won all four of his meetings against Kyrgios, including three at grand slams this year, and the Scot will now face France's Adrian Mannarino in round two.

The Australian bad-boy has been in the spotlight recently for comments made to Stanislas Wawrinka, yet was trailing from the start as his opponent battled on.
Murray meanwhile will continue his quest for a first Grand Slam since Wimbledon over two years ago.
So far this year he has made at least the last four in two of the three majors - though lost the Australian Open to world number one Novak Djokovic.
