NEW YORK - Defending champion Andy Murray was ousted from the US Open on Thursday, falling to Swiss ninth seed Stanislas Wawrinka 6-4 6-3 6-2 in a quarter-final shocker at Arthur Ashe Stadium.
Wawrinka reached his first Grand Slam semi-final by stunning the reigning Olympic and Wimbledon champion, booking a Saturday last-four date against either world number one Novak Djokovic or Russian 21st seed Mikhail Youzhny.
Spanish second seed Rafael Nadal and French eighth seed Richard Gasquet will meet in Saturday's other semi-final.
"It feels amazing for sure, especially after that match against the defending champion," Wawrinka said. "It was a crazy match for me to beat him in three sets."
Relentless pressure from Wawrinka, who is deeper than 17-time Grand Slam champion compatriot Roger Federer in a slam for the first time in his career, led to a Murray meltdown that doomed his repeat dreams.
"He played great. That was the hardest part about the match," Murray said.
"He just hit the ball extremely well. I didn't create a break point chance. He served well. He hit a lot of lines, was going for big shots, and he played too well."
A grim-faced Murray set a record for hustling to the interview room, arriving before Wawrinka could even leave the court after the match, the 26-year-old Scotsman's stoic visage a sign of his unhappiness.
"I would have liked to have played a little bit better," Murray said. "It's a shame I had to play a bad match today."
For only the second time in 146 grand slam matches, Murray failed to manage even a break point against an opponent, and it came on a day when Wawrinka ignored the wind to fire 45 winners, three times Murray's total.
"The first set was not really easy. It was very windy. We were trying to find the game," Wawrinka said. "To get that gave me a little bit of confidence for sure.
"I was trying to focus on what I did, playing solid and aggressive, to go for taking the match and not let him come back."
