NEW YORK - Andy Murray yelled at himself on the court, screamed in his chair and smashed a racquet and when the nightmare loss finally ended, he raced off the court as if he could not escape from it fast enough.
Such was the meltdown for the defending US Open champion as he crashed out of the US Open on Thursday, with Swiss ninth seed Stanislas Wawrinka dumping the British third seed 6-4, 6-3, 6-2 without even facing a break point.
The 26-year-old Scotsman had been enjoying a dream run with 2012 London Olympic gold, his first Grand Slam victory at last year's US Open and a long-sought Wimbledon triumph two months ago.
Beyond the mental burden and physical toll of his greatest Grand Slam success, Murray raised expectations after becoming the first British man since Fred Perry in 1936 to win the Wimbledon singles crown.
"I don't know if I'm meant to win every Grand Slam I play or be in the final," Murray said. "It's just very, very difficult just now. With the guys around us, it's very challenging."
Wawrinka sent Murray crashing out to reach his first Gramd Slam semi-final without facing a break chance, only the second time in 146 Slam matches that Murray could not manage a break-point against a rival.
"I didn't get into enough return games, which is disappointing," Murray said. "That's normally something I do pretty well. I always give myself opportunities to break serve, and I didn't today."
The emotional finish of closing out Wimbledon, Murray feeling the hopes of his homeland and the weight of history as he tried to finish off world number one Novak Djokovic, has made it tougher in the weeks since.
