The British tennis player Andy Murray hobbled out of the U.S. Open, beaten in four sets in the third round by Switzerland's Stanislas Wawrinka after his ailing body let him down.
Struggling to run at full speed after requiring treatment to his legs, elbow and neck, a clearly frustrated Murray appeared powerless to stop Wawrinka, who was battling his own injury problems but still played superbly, from pulling off the biggest upset of the championship.
His temperament has been an issue for him earlier in his career, but the fourthseed says that wasn't the problem today.
Murray says he was struggling physically and got frustrated as he felt his chances of doing well in New York slippign away.
Wawrinka, seeded 25th, advanced to play American Sam Querrey in the fourth round although the big winner could well be Rafa Nadal, who was drawn to face Murray in the semi-finals.
The Spaniard, getting better with each match on the back of a new and improved serve, overpowered France's Gilles Simon 6-4 6-4 6-2 to steam into the fourth round without dropping a single service game in three matches.
