Kyrgios criticised during US Open first-round loss to Andy Murray 'He thinks he's a vaudeville entertainer,' says original tennis brat John McEnroe lashed Nick Kyrgios's "bonehead" behaviour as the most polarising personality in tennis made a first-round exit from the US Open in New York. McEnroe was left flabbergasted by Kyrgios's audacious shot selection during his 7-5, 6-3, 4-6, 6-1 loss to Scottish third seed Andy Murray at Flushing Meadows.
