Third-seeded Briton Andy Murray put on a composed display to overcome the mercurial Nick Kyrgios 7-5 6-3 4-6 6-1 under the Arthur Ashe Stadium lights to reach the second round of the US Open on Tuesday.
The 20-year-old Kyrgios showed off his powerful serve and groundstrokes but the 37th-ranked Australian frequently sacrificed efficiency for showmanship and failed to take advantage of his numerous opportunities.
Murray, the 2012 US Open champion and 2013 Wimbledon winner, played straight man to the flippant Australian, who unnecessarily tried "tweener" shots through his legs and jumped extravagantly on routine forehands that he buried into the net.
Murray had beaten Kyrgios in straight sets in their three previous meetings, eliminating him this year from two other grand slams, in the Australian quarter-finals and third round of the French Open.
But the Scotsman still holds the Australian's game in high regard.
"He's played well pretty much in every grand slam tournament that he's been part of," Murray said about Kyrgios, who has twice reached grand slam quarter-finals.
"I expected a very tough match, and that's what I got."
The Australian, playing under an ATP Tour probation for crude personal comments made to Stan Wawrinka during a match in Montreal last month, should have made the contest much closer but could only convert three of 14 break point opportunities.
