No. 25 Wawrinka Knocks Out No. 4 Murray

The most shocking result of this weekend in U.S. Open tennis was, without a doubt, the stoic exit of Glasgow, Scotland's golden boy, Andy Murray, the world's No. 4 seed. Swiss player Stanislas Wawrinka, the No. 25 seed in the world, knocked Murray out on Sunday, 6‑7 (3), 7‑6 (4), 6‑3, 6‑3.

After the match, Murray gave a simple explanation for his loss to Wawrinka. “He played better than me," Murray said. “There's not a whole lot more to it. He had a chance to win the first set...didn't take it. I had a chance to win the second set...didn't take it. I just struggled from then on.”

During the third and fourth sets, Murray was visibly struggling. At one point, commentator John McEnroe mentioned that he thought Murray was fighting himself, along with Wawrinka. Murray even punched the strings of his racquet during one point in the match.

Murray said he would have to examine what exactly caused him to lose the match.

"There was a lot...that I was feeling on the court," Murray said. "So, I'm going to have to go look at why that was the case, and try and get better.”

Could it be that the pressure—and the wrath—from the British tabloids is getting to Murray? It's no secret that a British player hasn’t won a major since 1936.

“I don't think that is the reason why I lost the match today,” Murray said emphatically. “It hasn't been the reason I've lost any matches in a very, very long time, you know, since I was 21 years old. I think the last two, three years, it's not the reason why I've been losing matches."

Not surprisingly, Wawrinka said that he thought this was one of his best matches to date.

“I think all my game was pretty good,” Wawrinka said. “I was very aggressive...I'm very happy."
